Can you take Duragen with Seroquel?

The QUEtiapine in Seroquel has a major potential interaction with Abnormal Electrocardiogram.

Some atypical antipsychotic agents can prolong the QTc interval of the electrocardiogram in a dose-dependent manner. Electrolyte disturbances such as hypokalemia and hypomagnesemia may augment the prolongation effect of these agents on the QT interval and should be corrected prior to institution of therapy. In addition, patients who experience frequent, severe, or prolonged diarrhea may be subject to electrolyte losses and should be followed closely and managed accordingly during therapy with these agents. Atypical antipsychotic agents should be avoided in patients with a history of cardiac arrhythmias or other conditions that may increase the risk of torsade de pointes and/or sudden death, including bradycardia; hypokalemia or hypomagnesemia; congenital long QT syndrome; recent acute myocardial infarction; and/or uncompensated heart failure.

The estradiol in Duragen has a major potential interaction with Abnormal Uterine Bleeding.

The use of estrogens is contraindicated in patients with undiagnosed, abnormal vaginal bleeding. Prolonged (greater than 1 year), unopposed estrogen use (i.e. estrogen without concomitant progestin therapy) has been associated with a significant, dose-related risk of endometrial carcinoma. The risk may be offset substantially by the addition of a progestin but may not be completely abolished. Prior to initiating estrogen therapy, appropriate diagnostic tests should be performed in patients with abnormal vaginal bleeding to rule out endometrial malignancy. The same applies if recurrent or persistent bleeding develops during estrogen therapy.

The QUEtiapine in Seroquel has a major potential interaction with Alcoholism.

The use of neuroleptic agents is contraindicated in patients with acute alcohol intoxication exhibiting depressed vital signs. The central nervous system depressant effects of neuroleptic agents may be additive with those of alcohol. Severe respiratory depression and respiratory arrest may occur. Therapy with neuroleptic agents should be administered cautiously in patients who might be prone to acute alcohol intake.

The QUEtiapine in Seroquel has a moderate potential interaction with Alcoholism.

Antipsychotic and neuroleptic drugs can lower the seizure threshold and trigger seizures in a dose-dependent manner. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Therapy with these drugs should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism.

The QUEtiapine in Seroquel has a major potential interaction with Altered Consciousness.

The use of neuroleptic agents is contraindicated in comatose patients and patients with severe central nervous system depression. Neuroleptic agents may potentiate the CNS and respiratory depression in these patients.

The estradiol in Duragen has a moderate potential interaction with Angioedema.

The use of exogenous estrogens may induce or exacerbate symptoms of angioedema, particularly in women with hereditary angioedema. Consider the risk versus benefits of estrogen therapy. Close monitoring is recommended when prescribing these agents to patients predisposed to angioedema.

The QUEtiapine in Seroquel has a major potential interaction with Arrhythmia.

Some atypical antipsychotic agents can prolong the QTc interval of the electrocardiogram in a dose-dependent manner. Electrolyte disturbances such as hypokalemia and hypomagnesemia may augment the prolongation effect of these agents on the QT interval and should be corrected prior to institution of therapy. In addition, patients who experience frequent, severe, or prolonged diarrhea may be subject to electrolyte losses and should be followed closely and managed accordingly during therapy with these agents. Atypical antipsychotic agents should be avoided in patients with a history of cardiac arrhythmias or other conditions that may increase the risk of torsade de pointes and/or sudden death, including bradycardia; hypokalemia or hypomagnesemia; congenital long QT syndrome; recent acute myocardial infarction; and/or uncompensated heart failure.

The QUEtiapine in Seroquel has a moderate potential interaction with Arrhythmia.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

The estradiol in Duragen has a moderate potential interaction with Asthma.

Estrogens and progestogens may cause fluid retention, particularly when given in high dosages or for prolonged periods. Therapy with these agents should be administered cautiously in patients who have preexisting problems with excess fluid. In addition, patients with conditions that may be adversely affected by fluid accumulation, such as asthma, epilepsy, migraine, and cardiovascular or renal dysfunction, should be observed for exacerbation of their condition during estrogen and/or progestogen therapy.

The QUEtiapine in Seroquel has a major potential interaction with Bipolar Disorder.

Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term trials; these trials did not show increased risk in patients older than 24 years and risk was reduced in patients 65 years and older. Adult and pediatric patients with major depressive disorder may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressants; this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders; such disorders are the strongest predictors of suicide. Patients of all ages treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the first few months of drug therapy, and at times of dose changes. Family members/caregivers should be advised to monitor for changes in behavior and to notify the health care provider. Changing the therapeutic regimen (including discontinuing the medication) should be considered in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.

The estradiol in Duragen has a major potential interaction with Breast Cancer.

When treated with an estrogen, patients with breast cancer and bone metastases may develop severe hypercalcemia, in which case the drug should be stopped and measures be taken to reduce serum calcium levels.

The QUEtiapine in Seroquel has a moderate potential interaction with Breast Cancer.

The chronic use of neuroleptic agents can cause persistent elevations in prolactin levels due to antagonism of dopamine D2 receptors. Based on in vitro data, approximately one-third of human breast cancers are thought to be prolactin-dependent. The clinical significance of this observation with respect to long-term neuroleptic therapy is unknown. Chronic administration of neuroleptic drugs has been associated with mammary tumorigenesis in rodent studies but not in human clinical or epidemiologic studies. Until further data are available, therapy with neuroleptic agents should be administered cautiously in patients with a previously detected breast cancer. Caution is also advised in patients with preexisting hyperprolactinemia. Hyperprolactinemia may suppress hypothalamic gonadotrophin releasing hormone (GnRH), resulting in reduced pituitary gonadotropin secretion. This, in turn, may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients. Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds; however, the clinical significance of elevated serum prolactin levels is unknown for most patients. Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density in both female and male patients.

The QUEtiapine in Seroquel has a moderate potential interaction with Cataract.

Prolonged use of quetiapine was associated with the development of cataracts in dogs. Lens changes have also been observed in humans during chronic treatment with quetiapine, but a causal relationship has not been established. Long-term therapy with quetiapine should be administered cautiously in patients with a history of cataracts. Examination of the lens by slit lamp exam or other appropriately sensitive methods is recommended at initiation of treatment or shortly thereafter and at 6-month intervals during chronic treatment.

The estradiol in Duragen has a major potential interaction with Cerebral Vascular Disorder.

The use of estrogens is considered by manufacturers and some authorities to be contraindicated in patients with active thrombotic, thromboembolic, or thrombophilic disorders. The use of estrogen-containing oral contraceptives is additionally deemed contraindicated in patients with a history of such disorders and/or current cerebrovascular or coronary artery disease. Females with a history of migraines with aura are at an increased risk for stroke and this stroke risk may be further increased in females who have migraines with aura with use of combination oral contraceptives. Hypercoagulability and changes in various clotting factors and blood components have been observed in women receiving estrogen therapy. Known preexisting risk factors for increased thromboembolic or cardiovascular events include smoking, especially over age of 35; hypertension; hyperlipidemia; obesity; diabetes; age over 40; and lupus. Therapy with estrogens should be administered cautiously in the lowest effective dosage and only after careful consideration of risks and benefits. Estrogens should be avoided in patients with a history of thrombotic and thromboembolic disorders associated with estrogen use, except when used in the treatment of metastatic breast or prostatic malignancy.

The QUEtiapine in Seroquel has a moderate potential interaction with Cerebrovascular Insufficiency.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

The QUEtiapine in Seroquel has a moderate potential interaction with Dehydration.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

The QUEtiapine in Seroquel has a major potential interaction with Dementia.

Antipsychotic drugs are not approved for the treatment of patients with dementia-related psychosis. Older patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death; although the causes were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. A causal relationship with antipsychotic use has not been established. In controlled trials in older patients with dementia-related psychosis, patients randomized to risperidone, aripiprazole, and olanzapine had higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, compared to patients treated with placebo.

The QUEtiapine in Seroquel has a major potential interaction with Depression.

Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term trials; these trials did not show increased risk in patients older than 24 years and risk was reduced in patients 65 years and older. Adult and pediatric patients with major depressive disorder may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressants; this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders; such disorders are the strongest predictors of suicide. Patients of all ages treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the first few months of drug therapy, and at times of dose changes. Family members/caregivers should be advised to monitor for changes in behavior and to notify the health care provider. Changing the therapeutic regimen (including discontinuing the medication) should be considered in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.

The estradiol in Duragen has a moderate potential interaction with Diabetes Mellitus.

Impaired glucose tolerance has been observed in some patients administered oral contraceptives and appears to be related primarily to the estrogen dose. However, progestogens can increase insulin secretion and produce insulin resistance to varying degrees, depending on the agent. Caution and close monitoring are recommended in patients with diabetes mellitus during therapy with estrogens and/or progestogens, and adjustments made accordingly in their antidiabetic regimen.

The QUEtiapine in Seroquel has a moderate potential interaction with Diabetes Mellitus.

Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported with the use of atypical antipsychotic agents. Patients with diabetes should be monitored for worsening control of blood glucose when treated with these agents. It is recommended that patients with risk factors for diabetes mellitus starting treatment with atypical antipsychotics should undergo fasting blood glucose testing at the beginning of treatment, and periodically thereafter. Any patient treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Patients who develop symptoms of hyperglycemia during treatment with atypical antipsychotics should undergo fasting blood glucose testing. In some cases, hyperglycemia has resolved when treatment with these agents was discontinued; however, some patients required continuation of anti-diabetic treatment despite discontinuation of the atypical antipsychotic drug.

The QUEtiapine in Seroquel has a major potential interaction with Diarrhea.

Some atypical antipsychotic agents can prolong the QTc interval of the electrocardiogram in a dose-dependent manner. Electrolyte disturbances such as hypokalemia and hypomagnesemia may augment the prolongation effect of these agents on the QT interval and should be corrected prior to institution of therapy. In addition, patients who experience frequent, severe, or prolonged diarrhea may be subject to electrolyte losses and should be followed closely and managed accordingly during therapy with these agents. Atypical antipsychotic agents should be avoided in patients with a history of cardiac arrhythmias or other conditions that may increase the risk of torsade de pointes and/or sudden death, including bradycardia; hypokalemia or hypomagnesemia; congenital long QT syndrome; recent acute myocardial infarction; and/or uncompensated heart failure.

The QUEtiapine in Seroquel has a moderate potential interaction with Diarrhea.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

The QUEtiapine in Seroquel has a moderate potential interaction with Dysphagia.

Esophageal dysmotility and aspiration have been associated with the use of antipsychotic drugs. These drugs should be administered cautiously in patients at risk for aspiration pneumonia.

The estradiol in Duragen has a moderate potential interaction with Fluid Retention.

Estrogens and progestogens may cause fluid retention, particularly when given in high dosages or for prolonged periods. Therapy with these agents should be administered cautiously in patients who have preexisting problems with excess fluid. In addition, patients with conditions that may be adversely affected by fluid accumulation, such as asthma, epilepsy, migraine, and cardiovascular or renal dysfunction, should be observed for exacerbation of their condition during estrogen and/or progestogen therapy.

The estradiol in Duragen has a moderate potential interaction with Gallbladder Disease.

A two- to four-fold increase in risk of gallbladder disease has been noted in women receiving postmenopausal estrogen therapy. The risk for gallbladder disease may be less for premenopausal women using oral contraceptives containing low-dose estrogens and/or progestins. Therapy with estrogens should be administered cautiously in patients with preexisting gallbladder disease or a history of pregnancy-related cholestasis.

The QUEtiapine in Seroquel has a moderate potential interaction with Head Injury.

Antipsychotic and neuroleptic drugs can lower the seizure threshold and trigger seizures in a dose-dependent manner. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Therapy with these drugs should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism.

The estradiol in Duragen has a moderate potential interaction with Heart Failure.

Estrogens and progestogens may cause fluid retention, particularly when given in high dosages or for prolonged periods. Therapy with these agents should be administered cautiously in patients who have preexisting problems with excess fluid. In addition, patients with conditions that may be adversely affected by fluid accumulation, such as asthma, epilepsy, migraine, and cardiovascular or renal dysfunction, should be observed for exacerbation of their condition during estrogen and/or progestogen therapy.

The QUEtiapine in Seroquel has a moderate potential interaction with Heart Failure.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

The estradiol in Duragen has a major potential interaction with High Blood Pressure.

The risk of myocardial infarction and strokes, including those associated with oral contraceptive use and some estrogen use, is increased in patients with hypertension. Moreover, estrogens (and progestogens) may elevate blood pressure and worsen the hypertension, thus compounding the risk. Clinically significant blood pressure increases have been reported during estrogen therapy, particularly in patients receiving high dosages or treated with oral contraceptive combinations having high progestational activity. These effects also increase with duration of therapy and patient age. Therapy with estrogens should be administered cautiously in patients with preexisting hypertension. Some estrogen-based therapies, such as combined hormonal contraceptives, may be contraindicated in patients with uncontrolled hypertension or hypertension with vascular disease. Patients should be monitored for changes in cardiovascular status, and their antihypertensive regimen adjusted or estrogen therapy withdrawn as necessary. In patients requiring contraception, alternative methods should be considered for those who are hypertensive, over age 35, and smoke.

The QUEtiapine in Seroquel has a moderate potential interaction with High Blood Pressure.

The use of quetiapine may be associated with in increase systolic and diastolic blood pressure in children and adolescents. During the 26 week open-label clinical trial, one child with a reported history of hypertension experienced a hypertensive crisis. Blood pressure in children and adolescents should be measured at the beginning of, and periodically during treatment with quetiapine.

The estradiol in Duragen has a moderate potential interaction with High Cholesterol.

Estrogens may cause adverse lipid changes. Use of estrogens has been associated with elevations in triglyceride levels, particularly in women with pre-existing hypertriglyceridemia. Discontinue therapy if elevated triglycerides lead to pancreatitis. Manage hypercholesterolemia appropriately as indicated.

The QUEtiapine in Seroquel has a moderate potential interaction with High Cholesterol.

According to the manufacturer, patients treated with quetiapine in 3- to 6-week placebo-controlled trials had increases in cholesterol and triglyceride of 11% and 17%, respectively, compared to slight decreases in the placebo group. Patients with preexisting hyperlipidemia may require closer monitoring during quetiapine therapy, and adjustments made accordingly in their lipid-lowering regimen.

The QUEtiapine in Seroquel has a moderate potential interaction with High Cholesterol.

Atypical antipsychotic drugs have been associated with undesirable alterations in lipid levels. While all agents in the class have been shown to produce some changes, each drug has its own specific risk profile. Before or soon after initiation of antipsychotic medications, a fasting lipid profile should be obtained at baseline and monitored periodically during treatment.

The estradiol in Duragen has a major potential interaction with History, Thrombotic/Thromboembolic Disorder.

The use of estrogens is considered by manufacturers and some authorities to be contraindicated in patients with active thrombotic, thromboembolic, or thrombophilic disorders.

The QUEtiapine in Seroquel has a major potential interaction with Hypokalemia.

Some atypical antipsychotic agents can prolong the QTc interval of the electrocardiogram in a dose-dependent manner. Electrolyte disturbances such as hypokalemia and hypomagnesemia may augment the prolongation effect of these agents on the QT interval and should be corrected prior to institution of therapy. In addition, patients who experience frequent, severe, or prolonged diarrhea may be subject to electrolyte losses and should be followed closely and managed accordingly during therapy with these agents. Atypical antipsychotic agents should be avoided in patients with a history of cardiac arrhythmias or other conditions that may increase the risk of torsade de pointes and/or sudden death, including bradycardia; hypokalemia or hypomagnesemia; congenital long QT syndrome; recent acute myocardial infarction; and/or uncompensated heart failure.

The estradiol in Duragen has a moderate potential interaction with Hypoparathyroidism.

Estrogens should be used with caution in individuals with severe hypocalcemia or hypoparathyroidism. Estrogen-induced hypocalcemia may occur in patients with hypoparathyroidism; consider whether the benefits of estrogen therapy outweigh the risks.

The QUEtiapine in Seroquel has a moderate potential interaction with Hypotension.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

The estradiol in Duragen has a major potential interaction with Ischemic Heart Disease.

The use of estrogens is considered by manufacturers and some authorities to be contraindicated in patients with active thrombotic, thromboembolic, or thrombophilic disorders.

Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

The QUEtiapine in Seroquel has a moderate potential interaction with Leukemia.

Atypical antipsychotic agents with alpha-adrenergic blocking effects may cause priapism. The condition is characterized by prolonged, often painful erections lasting longer than 4 hours. If not treated promptly, priapism can cause irreversible damage to the erectile tissue. Therapy with these agents should be administered cautiously in patients with a history of priapism, conditions that may predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, leukemia, thalassemia), or anatomical deformations of the penis (e.g., angulation, cavernosal fibrosis, Peyronie's disease). Patients who experience an erection lasting longer than 4 hours, whether painful or not, should immediately discontinue the drug and seek emergency medical attention.

The estradiol in Duragen has a moderate potential interaction with Liver Disease.

Estrogens are primarily metabolized by the liver. Use of estrogen therapy is contraindicated in patients with liver dysfunction or disease. Patients with impaired hepatic function may be at increased risk for adverse effects associated with estrogen administration due to decreased drug clearance. Patients with hepatic hemangiomas are at increased risk of exacerbation with use of estrogens. Therapy with estrogens should be administered cautiously in patients with cholestatic jaundice associated with past estrogen use or with pregnancy. In addition, clinicians should be aware that estrogen therapy may affect liver function tests.

The QUEtiapine in Seroquel has a moderate potential interaction with Liver Disease.

The use of quetiapine may be associated with transient, asymptomatic elevations in serum transaminase. During a series of 3- to 6-week clinical trials, 6% of patients exposed to quetiapine experienced ALT (SGPT) elevations greater than three times the upper limit of normal, compared to 1% in the placebo group. Liver enzymes tended to increase within the first 3 weeks of therapy and return to baseline with continued treatment. Therapy with quetiapine should be administered cautiously in patients with signs and symptoms of hepatic impairment. Periodic assessment of serum transaminases should be performed in patients with significant hepatic disease.

The QUEtiapine in Seroquel has a moderate potential interaction with Liver Disease.

Most neuroleptic agents are extensively metabolized by the liver. The plasma concentrations of these agents may be increased and the half-lives prolonged in patients with impaired hepatic function. Therapy with neuroleptic agents should be administered cautiously in patients with significant liver disease. Lower initial dosages and slower titration may be appropriate.

The QUEtiapine in Seroquel has a major potential interaction with Magnesium Imbalance.

Some atypical antipsychotic agents can prolong the QTc interval of the electrocardiogram in a dose-dependent manner. Electrolyte disturbances such as hypokalemia and hypomagnesemia may augment the prolongation effect of these agents on the QT interval and should be corrected prior to institution of therapy.

The estradiol in Duragen has a moderate potential interaction with Migraine.

Estrogens and progestogens may cause fluid retention, particularly when given in high dosages or for prolonged periods. Therapy with these agents should be administered cautiously in patients who have preexisting problems with excess fluid. In addition, patients with conditions that may be adversely affected by fluid accumulation, such as asthma, epilepsy, migraine, and cardiovascular or renal dysfunction, should be observed for exacerbation of their condition during estrogen and/or progestogen therapy.

The QUEtiapine in Seroquel has a moderate potential interaction with Multiple Myeloma.

Atypical antipsychotic agents with alpha-adrenergic blocking effects may cause priapism. The condition is characterized by prolonged, often painful erections lasting longer than 4 hours. If not treated promptly, priapism can cause irreversible damage to the erectile tissue. Therapy with these agents should be administered cautiously in patients with a history of priapism, conditions that may predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, leukemia, thalassemia), or anatomical deformations of the penis (e.g., angulation, cavernosal fibrosis, Peyronie's disease). Patients who experience an erection lasting longer than 4 hours, whether painful or not, should immediately discontinue the drug and seek emergency medical attention.

The estradiol in Duragen has a major potential interaction with Neoplasia, Estrogen Dependent.

The use of estrogens is generally contraindicated in patients with known or suspected estrogen-dependent neoplasia such as breast and endometrial cancer, since it may stimulate tumor proliferation. High dosages of estrogens may be used for the palliative treatment of inoperable, metastatic breast cancer, but only in appropriately selected men and postmenopausal women.

The QUEtiapine in Seroquel has a major potential interaction with Neuroleptic Malignant Syndrome.

The central dopaminergic blocking effects of neuroleptic agents may precipitate or aggravate a potentially fatal symptom complex known as neuroleptic malignant syndrome (NMS). NMS is observed most frequently when high-potency agents like haloperidol are administered intramuscularly, but may occur with any neuroleptic agent given for any length of time. Clinical manifestations of NMS include hyperpyrexia, muscle rigidity, altered mental status and autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac arrhythmias). Additional signs may include elevated creatine phosphokinase, myoglobinuria, and acute renal failure. Neuroleptic agents should not be given to patients with active NMS and should be immediately discontinued if currently being administered in such patients. In patients with a history of NMS, introduction or reintroduction of neuroleptic agents should be carefully considered, since NMS may recur.

The QUEtiapine in Seroquel has a moderate potential interaction with Neutropenia.

Cases of leukopenia, neutropenia, and agranulocytosis have been reported with the use of atypical antipsychotic agents. Patients with preexisting low white blood cell count may be at increased risk. Therapy with these agents should be administered cautiously in patients with a history of, or predisposition to, decreased white blood cell or neutrophil counts. Clinical monitoring of hematopoietic function is recommended. At the first sign of a clinically significant decline in white blood cells, discontinuation of atypical antipsychotic therapy should be considered in the absence of other causative factors, and the patient closely monitored for fever or other signs and symptoms of infection.

The estradiol in Duragen has a moderate potential interaction with Pancreatitis.

Estrogens may cause adverse lipid changes. Use of estrogens has been associated with elevations in triglyceride levels, particularly in women with pre-existing hypertriglyceridemia. Discontinue therapy if elevated triglycerides lead to pancreatitis. Manage hypercholesterolemia appropriately as indicated.

The QUEtiapine in Seroquel has a moderate potential interaction with Parkinsonism.

The use of neuroleptic agents is associated with pseudo-parkinsonian symptoms such as akinesia, bradykinesia, tremors, pill-rolling motion, cogwheel rigidity, and postural abnormalities including stooped posture and shuffling gait. The onset is usually 1 to 2 weeks following initiation of therapy or an increase in dosage. Older neuroleptic agents such as haloperidol are more likely to induce these effects, and their use may be contraindicated in patients with Parkinson's disease or parkinsonian symptoms.

The QUEtiapine in Seroquel has a moderate potential interaction with Penis Disorders.

Atypical antipsychotic agents with alpha-adrenergic blocking effects may cause priapism. The condition is characterized by prolonged, often painful erections lasting longer than 4 hours. If not treated promptly, priapism can cause irreversible damage to the erectile tissue. Therapy with these agents should be administered cautiously in patients with a history of priapism, conditions that may predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, leukemia, thalassemia), or anatomical deformations of the penis (e.g., angulation, cavernosal fibrosis, Peyronie's disease). Patients who experience an erection lasting longer than 4 hours, whether painful or not, should immediately discontinue the drug and seek emergency medical attention.

The estradiol in Duragen has a moderate potential interaction with Renal Dysfunction.

Estrogens and progestogens may cause fluid retention, particularly when given in high dosages or for prolonged periods. Therapy with these agents should be administered cautiously in patients who have preexisting problems with excess fluid. In addition, patients with conditions that may be adversely affected by fluid accumulation, such as asthma, epilepsy, migraine, and cardiovascular or renal dysfunction, should be observed for exacerbation of their condition during estrogen and/or progestogen therapy.

The QUEtiapine in Seroquel has a major potential interaction with Respiratory Arrest.

The use of neuroleptic agents is contraindicated in comatose patients and patients with severe central nervous system depression. Neuroleptic agents may potentiate the CNS and respiratory depression in these patients.

The estradiol in Duragen has a moderate potential interaction with Seizures.

Estrogens and progestogens may cause fluid retention, particularly when given in high dosages or for prolonged periods. Therapy with these agents should be administered cautiously in patients who have preexisting problems with excess fluid. In addition, patients with conditions that may be adversely affected by fluid accumulation, such as asthma, epilepsy, migraine, and cardiovascular or renal dysfunction, should be observed for exacerbation of their condition during estrogen and/or progestogen therapy.

The QUEtiapine in Seroquel has a moderate potential interaction with Seizures.

Antipsychotic and neuroleptic drugs can lower the seizure threshold and trigger seizures in a dose-dependent manner. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Therapy with these drugs should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism.

The QUEtiapine in Seroquel has a moderate potential interaction with Sickle Cell Anemia.

Atypical antipsychotic agents with alpha-adrenergic blocking effects may cause priapism. The condition is characterized by prolonged, often painful erections lasting longer than 4 hours. If not treated promptly, priapism can cause irreversible damage to the erectile tissue. Therapy with these agents should be administered cautiously in patients with a history of priapism, conditions that may predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, leukemia, thalassemia), or anatomical deformations of the penis (e.g., angulation, cavernosal fibrosis, Peyronie's disease). Patients who experience an erection lasting longer than 4 hours, whether painful or not, should immediately discontinue the drug and seek emergency medical attention.

The QUEtiapine in Seroquel has a moderate potential interaction with Syncope.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

The QUEtiapine in Seroquel has a moderate potential interaction with Tardive Dyskinesia.

Tardive dyskinesia (TD) has occurred in patients treated with antipsychotic drugs; the syndrome consists of potentially irreversible, involuntary, dyskinetic movements. The risk appears highest in older patients (particularly older women) but it is not possible to predict which patients are likely to develop TD; whether antipsychotic drugs differ in their potential to cause TD is unknown. The risk of TD and the likelihood that it will become irreversible increase with the duration of therapy and the total cumulative dose. The syndrome can develop after relatively brief treatment periods, even at low dosages; it may also occur after discontinuation of therapy. TD may remit (partially or completely) upon discontinuation of antipsychotic therapy, although antipsychotic therapy itself may suppress (or partially suppress) signs/symptoms of TD, possibly masking the underlying process; the effect of symptomatic suppression on the long-term course of TD is unknown. In patients with preexisting drug-induced TD, initiating or increasing the dosage of antipsychotic therapy may temporarily mask the symptoms of TD but could eventually worsen the condition. In patients requiring chronic therapy, the lowest dose and shortest duration of therapy producing a satisfactory clinical response are recommended; the need for continued therapy should be reassessed periodically. If signs/symptoms of TD occur during antipsychotic therapy, discontinuation of the offending agent should be considered; however, some patients may require treatment despite the presence of TD.

The QUEtiapine in Seroquel has a moderate potential interaction with Thalassemia.

Atypical antipsychotic agents with alpha-adrenergic blocking effects may cause priapism. The condition is characterized by prolonged, often painful erections lasting longer than 4 hours. If not treated promptly, priapism can cause irreversible damage to the erectile tissue. Therapy with these agents should be administered cautiously in patients with a history of priapism, conditions that may predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, leukemia, thalassemia), or anatomical deformations of the penis (e.g., angulation, cavernosal fibrosis, Peyronie's disease). Patients who experience an erection lasting longer than 4 hours, whether painful or not, should immediately discontinue the drug and seek emergency medical attention.

The estradiol in Duragen has a major potential interaction with Thrombotic/Thromboembolic Disorder.

The use of estrogens is considered by manufacturers and some authorities to be contraindicated in patients with active thrombotic, thromboembolic, or thrombophilic disorders. The use of estrogen-containing oral contraceptives is additionally deemed contraindicated in patients with a history of such disorders and/or current cerebrovascular or coronary artery disease. Females with a history of migraines with aura are at an increased risk for stroke and this stroke risk may be further increased in females who have migraines with aura with use of combination oral contraceptives. Hypercoagulability and changes in various clotting factors and blood components have been observed in women receiving estrogen therapy. Known preexisting risk factors for increased thromboembolic or cardiovascular events include smoking, especially over age of 35; hypertension; hyperlipidemia; obesity; diabetes; age over 40; and lupus. Therapy with estrogens should be administered cautiously in the lowest effective dosage and only after careful consideration of risks and benefits. Estrogens should be avoided in patients with a history of thrombotic and thromboembolic disorders associated with estrogen use, except when used in the treatment of metastatic breast or prostatic malignancy.

The estradiol in Duragen has a moderate potential interaction with Thyroid Disease.

When administering estrogen and/or progestogen therapy in patients with thyroid disorders, clinicians should be aware that these hormones may affect thyroid function tests. Patients on thyroid replacement therapy may require higher doses of thyroid hormone and appropriate monitoring. Changes have mostly been reported with the use of combination oral contraceptives. Specifically, thyroid-binding globulin (TBG) may be increased, resulting in elevated circulating total thyroid hormone, as measured by PBI (protein-bound iodine), T4 by column or radioimmunoassay, or T3 by radioimmunoassay. Free T3 resin uptake may be decreased. On the contrary, a decrease in TBG and, consequently, thyroxine concentration, has been reported by the manufacturers of the progestin-only (norethindrone) oral contraceptives.

The QUEtiapine in Seroquel has a moderate potential interaction with Thyroid Disease.

During clinical trials, the use of quetiapine was associated with a dose-related decrease in total and free thyroxine (T4) levels that reached approximately 20% at the higher end of the therapeutic dose range and peaked within the first 2 to 4 weeks of treatment. Generally, the changes were of no clinical significance and were reversible following discontinuation of quetiapine regardless of the duration of treatment. TBG levels were not altered in any patient, while TSH increased in 0.4% (10/2386) of patients, some of whom required thyroid replacement therapy. Therapy with quetiapine should be administered cautiously in patients with thyroid disease. Closer monitoring of thyroid function may be appropriate following initiation or cessation of quetiapine.

The QUEtiapine in Seroquel has a moderate potential interaction with Vomiting.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

The QUEtiapine in Seroquel has a moderate potential interaction with Weight Loss.

Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported with the use of atypical antipsychotic agents. Patients with diabetes should be monitored for worsening control of blood glucose when treated with these agents. It is recommended that patients with risk factors for diabetes mellitus starting treatment with atypical antipsychotics should undergo fasting blood glucose testing at the beginning of treatment, and periodically thereafter. Any patient treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Patients who develop symptoms of hyperglycemia during treatment with atypical antipsychotics should undergo fasting blood glucose testing. In some cases, hyperglycemia has resolved when treatment with these agents was discontinued; however, some patients required continuation of anti-diabetic treatment despite discontinuation of the atypical antipsychotic drug.

The QUEtiapine in Seroquel has a moderate potential interaction with Weight Loss.

Weight gain has been observed with atypical antipsychotic use. While all agents in the class have been shown to produce some changes, each drug has its own specific risk profile. When treating pediatric patients with atypical antipsychotic agents, weight gain should be monitored and assessed against that expected for normal growth. Monitor weight at baseline and frequently thereafter.
