Interactions between Pentamidine and Taytulla

Pentamidine has a major potential interaction with Abnormal Glucose Tolerance.

Pentamidine may have direct toxic effects on beta cells of the pancreas. Hypoglycemia, which may be severe and/or prolonged, as well as hyperglycemia and insulin-dependent diabetes mellitus, the latter of which may be irreversible, have been reported. The onset of pentamidine-induced hypoglycemia generally varied from 5 to 7 days after start of therapy to several days after therapy stops. In some cases, hyperglycemia and progression to diabetes followed, although these effects have occurred independently also. Pancreatic toxicity has been reported with both parenteral use and, less frequently, oral inhalation of pentamidine. The risk appears to be related to total cumulative dosage and prior therapy with the drug, particularly within the last 3 months. Therapy with pentamidine, regardless of route of administration, should be administered cautiously in patients with or predisposed to diabetes or spontaneous hypoglycemia. Blood glucose should be monitored more closely during and for some time after pentamidine therapy.

The norethindrone in Taytulla has a major potential interaction with Abnormal Uterine Bleeding.

The use of contraceptives is contraindicated when there is an undiagnosed abnormal genital bleeding. Adequate diagnostic measures should be undertaken to rule out the presence of any malignancy.

The ethinyl estradiol in Taytulla 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.

Pentamidine has a major potential interaction with Alcoholism.

Acute and potentially fatal pancreatitis has been reported with parenteral use and, rarely, oral inhalation of pentamidine. Patients with a history of or known risk factors for pancreatitis, such as alcohol abuse or hypertriglyceridemia, should be monitored closely during therapy with pentamidine. Therapy should be discontinued at the first signs or symptoms suggestive of pancreatitis (e.g., nausea, vomiting, abdominal pain, hyperamylasemia with dysglycemia, rising triglycerides, decreasing serum calcium), and preferably permanently discontinued if clinical pancreatitis develops.

The ethinyl estradiol in Taytulla 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.

Pentamidine has a moderate potential interaction with Asthma.

Orally inhaled pentamidine may induce bronchospasm and cough. Therapy with aerosolized pentamidine should be administered cautiously in patients with severe bronchospastic disease or a history of extensive smoking. Pretreatment with a beta-2 adrenergic bronchodilator prior to each dose of aerosolized pentamidine may be helpful in patients who experience respiratory symptoms from the medication.

The ethinyl estradiol and norethindrone in Taytulla both have 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.

Pentamidine has a major potential interaction with Bone Marrow Depression/Low Blood Counts.

Hematologic toxicities have been associated occasionally with the parenteral use of pentamidine. Leukopenia and, less frequently, thrombocytopenia have been reported and may be severe (e.g., leukocyte count < 1000/mm3, platelet count < 20,000/mm3). Anemia, neutropenia, pancytopenia, and prolonged clotting time have occurred rarely. Therapy with pentamidine should be administered cautiously in patients with preexisting blood dyscrasias and/or bone marrow depression. Complete blood counts, including platelets, should be performed prior to and periodically during and after therapy. Marked depression of blood counts may be indication for withdrawal of pentamidine therapy.

Pentamidine has a major potential interaction with Bone Marrow Depression/Low Blood Counts.

Orally inhaled pentamidine is generally not associated with significant systemic toxicity due to limited absorption from the respiratory tract. However, detectable serum concentrations have been reported in some patients receiving chronic oral inhalation therapy, and systemic adverse effects have occasionally occurred. Therefore, when pentamidine is administered by oral inhalation, clinicians may want to heed the usual warnings and precautions associated with parenteral use of the drug.

The norethindrone in Taytulla has a major potential interaction with Breast Cancer.

The use of progestogens is considered by manufacturers to be contraindicated in patients with existing or suspected malignancy of the breast. Some supportive data are available for medroxyprogesterone. Specifically, medroxyprogesterone treatment may be associated with breast cancer, primarily when the drug is administered intramuscularly. A pooled analysis of two case-control studies, one from the World Health Organization and the other from New Zealand, revealed a small overall relative risk of breast cancer in women who have ever used intramuscular medroxyprogesterone acetate. The relative risk was higher in the subgroup of women who had initiated therapy within the previous 5 years. Thus, an increased risk (approximately 2-fold) is associated with intramuscular medroxyprogesterone use in the first 5 years. A more recent U.S. study also found a statistically significant increase in breast cancer risk among recent users (defined as last use within the past five years) who used depo-medroxyprogesterone acetate for 12 months or longer.

The ethinyl estradiol in Taytulla 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.

Pentamidine has a major potential interaction with Cardiovascular Conditions and Disorders.

Orally inhaled pentamidine is generally not associated with significant systemic toxicity due to limited absorption from the respiratory tract. However, detectable serum concentrations have been reported in some patients receiving chronic oral inhalation therapy, and systemic adverse effects have occasionally occurred. Therefore, when pentamidine is administered by oral inhalation, clinicians may want to heed the usual warnings and precautions associated with parenteral use of the drug.

Pentamidine has a major potential interaction with Cardiovascular Conditions and Disorders.

Parenteral use of pentamidine may be associated with serious and potentially fatal cardiovascular effects. Sudden and severe hypotension, cardiorespiratory arrest, ventricular tachycardia, torsade de pointes, ECG abnormalities, and facial flushing have been reported. Therapy with pentamidine should be administered cautiously in all patients but in particular, those with preexisting hypotension, severe cardiovascular disease, or conditions that could be exacerbated by hypotension such as a history of myocardial infarction, angina, or ischemic stroke. Patients should be in a supine position and blood pressure monitored closely during and after administration of the drug until blood pressure is stable. Equipment for emergency resuscitation should be readily available if the parenteral route is used. ECGs should also be performed before, during, and after parenteral therapy.

The norethindrone in Taytulla has a major potential interaction with Cerebral Vascular Disorder.

The use of progestogens, in general, is considered by manufacturers to be contraindicated in patients with active thrombophlebitis, cerebrovascular disease, or a current or past history of thromboembolic disorders. While the role of progestogens in the development of thromboembolic events associated with hormonal therapy is often unclear and thought to be secondary to that of estrogens, it may not be insignificant. Medroxyprogesterone, a common progestational agent, has been shown to produce a hypercoagulable state in high dosages. Whether or not this effect contributes to the development of thrombotic events is unknown. However, thrombophlebitis and pulmonary embolism have been reported with megestrol, an antineoplastic and progestational agent. In addition, an increased risk of nonfatal venous thrombosis has been associated with oral contraceptive combinations containing desogestrel or gestodene relative to those that contain other progestins (e.g., levonorgestrel, norethindrone), suggesting some degree of hemostatic effect by progestogens.

The ethinyl estradiol in Taytulla 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.

Pentamidine has a major potential interaction with Cerebrovascular Insufficiency.

Orally inhaled pentamidine is generally not associated with significant systemic toxicity due to limited absorption from the respiratory tract. However, detectable serum concentrations have been reported in some patients receiving chronic oral inhalation therapy, and systemic adverse effects have occasionally occurred. Therefore, when pentamidine is administered by oral inhalation, clinicians may want to heed the usual warnings and precautions associated with parenteral use of the drug.

Pentamidine has a moderate potential interaction with COPD.

Orally inhaled pentamidine may induce bronchospasm and cough. Therapy with aerosolized pentamidine should be administered cautiously in patients with severe bronchospastic disease or a history of extensive smoking. Pretreatment with a beta-2 adrenergic bronchodilator prior to each dose of aerosolized pentamidine may be helpful in patients who experience respiratory symptoms from the medication.

Pentamidine has a major potential interaction with Dehydration.

Patients who are dehydrated may be particularly susceptible to the nephrotoxic and hypotensive effects associated with the parenteral use of pentamidine. Dehydration should preferably be corrected prior to initiation of therapy. In patients who may be at risk for dehydration, such as those with severe and/or prolonged diarrhea or vomiting, fluid status and blood pressure should be monitored closely. If signs of renal irritation develop during therapy, hydration should be increased as indicated, accompanied by a reduction in dosage if necessary. Therapy should be withdrawn if urinary output decreases progressively or azotemia increases.

Orally inhaled pentamidine is generally not associated with significant systemic toxicity due to limited absorption from the respiratory tract. However, detectable serum concentrations have been reported in some patients receiving chronic oral inhalation therapy, and systemic adverse effects have occasionally occurred. Therefore, when pentamidine is administered by oral inhalation, clinicians may want to heed the usual warnings and precautions associated with parenteral use of the drug.

The ethinyl estradiol and norethindrone in Taytulla both have a moderate potential interaction with Depression.

The use of oral contraceptives has been associated with an increased incidence of depression. It is uncertain whether this effect is related to the estrogenic or the progestogenic component of the contraceptive, although excess progesterone activity is associated with depression. Patients with a history of depression receiving estrogen and/or progestogen therapy should be followed closely. The manufacturer of medroxyprogesterone recommends monitoring patients who have a history of depression and to not re- administer medroxyprogesterone if depression recurs.

Pentamidine has a major potential interaction with Diabetes Mellitus.

Pentamidine may have direct toxic effects on beta cells of the pancreas. Hypoglycemia, which may be severe and/or prolonged, as well as hyperglycemia and insulin-dependent diabetes mellitus, the latter of which may be irreversible, have been reported. The onset of pentamidine-induced hypoglycemia generally varied from 5 to 7 days after start of therapy to several days after therapy stops. In some cases, hyperglycemia and progression to diabetes followed, although these effects have occurred independently also. Pancreatic toxicity has been reported with both parenteral use and, less frequently, oral inhalation of pentamidine. The risk appears to be related to total cumulative dosage and prior therapy with the drug, particularly within the last 3 months. Therapy with pentamidine, regardless of route of administration, should be administered cautiously in patients with or predisposed to diabetes or spontaneous hypoglycemia. Blood glucose should be monitored more closely during and for some time after pentamidine therapy.

The ethinyl estradiol and norethindrone in Taytulla both have 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.

Pentamidine has a major potential interaction with Diarrhea.

Orally inhaled pentamidine is generally not associated with significant systemic toxicity due to limited absorption from the respiratory tract. However, detectable serum concentrations have been reported in some patients receiving chronic oral inhalation therapy, and systemic adverse effects have occasionally occurred.

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 ethinyl estradiol in Taytulla 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 ethinyl estradiol and norethindrone in Taytulla both have 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 ethinyl estradiol and norethindrone in Taytulla both have a major potential interaction with Hepatic Tumor.

The use of oral contraceptives is contraindicated in patients with liver tumors. An increased risk of benign hepatic adenomas and hepatocellular carcinomas has been associated with long-term, oral estrogen- progestin contraceptive use of at least 4 years and 8 years, respectively. Although these tumors are rare and have not been reported with other types of estrogen or progestogen therapies, any preparation containing estrogens and/or progestogens should probably be avoided in patients with existing tumors of the liver. Hepatic hemangiomas and nodular hyperplasia of the liver have been reported with isolated estrogen therapy.

The ethinyl estradiol in Taytulla 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 norethindrone in Taytulla has a moderate potential interaction with High Blood Pressure.

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.

Pentamidine has a major potential interaction with High Cholesterol.

Acute and potentially fatal pancreatitis has been reported with parenteral use and, rarely, oral inhalation of pentamidine. Patients with a history of or known risk factors for pancreatitis, such as alcohol abuse or hypertriglyceridemia, should be monitored closely during therapy with pentamidine. Therapy should be discontinued at the first signs or symptoms suggestive of pancreatitis (e.g., nausea, vomiting, abdominal pain, hyperamylasemia with dysglycemia, rising triglycerides, decreasing serum calcium), and preferably permanently discontinued if clinical pancreatitis develops.

The norethindrone in Taytulla has a moderate potential interaction with High Cholesterol.

Some progestogenic agents may elevate plasma LDL levels and/or lower HDL levels, although data have been inconsistent. Patients with preexisting hyperlipidemia may require closer monitoring during progestogen therapy, and adjustments made accordingly in their lipid-lowering regimen.

The ethinyl estradiol in Taytulla 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 ethinyl estradiol in Taytulla 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 norethindrone in Taytulla has a major potential interaction with Liver Disease.

The use of progestogens, in general, is contraindicated in patients with impaired hepatic function or liver disease. There are little or no data concerning the pharmacokinetic disposition of the different progestogens in patients with hepatic disease. However, most hormones, including progestational hormones, are known to be extensively metabolized by the liver. Medroxyprogesterone should not be used by women with significant liver disease and should be discontinued if jaundice or disturbances of liver function occur.

Pentamidine has a moderate potential interaction with Liver Disease.

Parenteral use of pentamidine may cause elevated liver function tests. Therapy with pentamidine should be administered cautiously in patients with hepatic impairment. Serum transaminase, alkaline phosphatase, and bilirubin levels should be measured periodically, and the dosing frequency reduced or therapy withdrawn if significant elevations develop.

The ethinyl estradiol in Taytulla 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 ethinyl estradiol in Taytulla has a moderate potential interaction with Melasma.

The use of exogenous estrogens may occasionally cause chloasma, especially in women with a history of chloasma gravidarum. Women with a tendency to chloasma should avoid exposure to the sun or ultraviolet radiation while taking combination oral contraceptives.

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 ethinyl estradiol in Taytulla 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.

Pentamidine has a major potential interaction with Pancreatitis.

Acute and potentially fatal pancreatitis has been reported with parenteral use and, rarely, oral inhalation of pentamidine. Patients with a history of or known risk factors for pancreatitis, such as alcohol abuse or hypertriglyceridemia, should be monitored closely during therapy with pentamidine. Therapy should be discontinued at the first signs or symptoms suggestive of pancreatitis (e.g., nausea, vomiting, abdominal pain, hyperamylasemia with dysglycemia, rising triglycerides, decreasing serum calcium), and preferably permanently discontinued if clinical pancreatitis develops.

The ethinyl estradiol in Taytulla 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.

Pentamidine has a major potential interaction with Renal Dysfunction.

Parenteral use of pentamidine may be associated with nephrotoxicity, usually evidenced by elevations in BUN or serum creatinine concentrations. Azotemia has also been reported. Although pentamidine-induced nephrotoxicity is generally mild to moderate in severity and reversible following discontinuation of the drug, acute renal failure has occurred occasionally. Limited evidence suggests that nephrotoxicity may occur more frequently in patients with AIDS and may be accompanied by severe, sometimes life-threatening hyperkalemia. Therapy with pentamidine should be administered cautiously in patients with renal impairment. The need for dosage adjustments is uncertain. To minimize the risk of toxicity, patients should be adequately hydrated and use with other nephrotoxic agents should be avoided. Renal function and serum potassium levels should be closely monitored, and the dosing frequency reduced or therapy withdrawn if toxicity develops.

The ethinyl estradiol in Taytulla has a major potential interaction with Smoking.

Cigarette smoking increases the risk of serious cardiovascular events from estrogen-containing combination oral contraceptives (COC). This risk increases with age, particularly in females over 35 years of age, and with the number of cigarettes smoked. For this reason, COCs are contraindicated in females who are over 35 years of age and smoke.

The norethindrone in Taytulla has a major potential interaction with Thrombotic/Thromboembolic Disorder.

The use of progestogens, in general, is considered by manufacturers to be contraindicated in patients with active thrombophlebitis, cerebrovascular disease, or a current or past history of thromboembolic disorders. While the role of progestogens in the development of thromboembolic events associated with hormonal therapy is often unclear and thought to be secondary to that of estrogens, it may not be insignificant. Medroxyprogesterone, a common progestational agent, has been shown to produce a hypercoagulable state in high dosages. Whether or not this effect contributes to the development of thrombotic events is unknown. However, thrombophlebitis and pulmonary embolism have been reported with megestrol, an antineoplastic and progestational agent. In addition, an increased risk of nonfatal venous thrombosis has been associated with oral contraceptive combinations containing desogestrel or gestodene relative to those that contain other progestins (e.g., levonorgestrel, norethindrone), suggesting some degree of hemostatic effect by progestogens.

The ethinyl estradiol in Taytulla 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 ethinyl estradiol and norethindrone in Taytulla both have 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.

Pentamidine has a major potential interaction with Vomiting.

Patients who are dehydrated may be particularly susceptible to the nephrotoxic and hypotensive effects associated with the parenteral use of pentamidine. Dehydration should preferably be corrected prior to initiation of therapy. In patients who may be at risk for dehydration, such as those with severe and/or prolonged diarrhea or vomiting, fluid status and blood pressure should be monitored closely. If signs of renal irritation develop during therapy, hydration should be increased as indicated, accompanied by a reduction in dosage if necessary. Therapy should be withdrawn if urinary output decreases progressively or azotemia increases.

Pentamidine has a major potential interaction with Vomiting.

Orally inhaled pentamidine is generally not associated with significant systemic toxicity due to limited absorption from the respiratory tract. However, detectable serum concentrations have been reported in some patients receiving chronic oral inhalation therapy, and systemic adverse effects have occasionally occurred. Therefore, when pentamidine is administered by oral inhalation, clinicians may want to heed the usual warnings and precautions associated with parenteral use of the drug.

The norethindrone in Taytulla has a minor potential interaction with Weight Loss.

Progestogens can cause weight gain, which may be significant (as is the case with parenteral medroxyprogesterone) and undesirable in obese patients attempting to lose weight.
