Abnormal Uterine Bleeding
Major:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
Acute Alcohol Intoxication
Major:
estazolam
Estazolam has a major potential interaction with Acute Alcohol Intoxication.
The use of benzodiazepines with alcohol is not recommended. Patients with acute alcohol intoxication exhibit depressed vital signs. The central nervous system depressant effects of benzodiazepines may be additive with those of alcohol, and severe respiratory depression and death may occur. Therapy with benzodiazepines should be administered cautiously in patients who might be prone to acute alcohol intake.
Angioedema
Moderate:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
Asphyxia
Major:
estazolam
Estazolam has a major potential interaction with Asphyxia.
Benzodiazepines may cause respiratory depression and apnea, usually when given in high dosages and/or by intravenous administration. However, some patients may be susceptible at commonly used dosages, including the elderly, debilitated or severely ill patients, those receiving other CNS depressants, and those with limited ventilatory reserve, chronic pulmonary insufficiency or other respiratory disorders. Therapy with benzodiazepines should be administered cautiously in these patients. Appropriate monitoring and individualization of dosage are particularly important, and equipment for resuscitation should be immediately available if the parenteral route is used. Benzodiazepines, especially injectable formulations, should generally be avoided in patients with sleep apnea, severe respiratory insufficiency, or hypoxia.
Asthma
Moderate:
Kelnor 1/35
The ethinyl estradiol and ethynodiol in Kelnor 1/35 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.
Breast Cancer
Major:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
Cerebral Vascular Disorder
Major:
Kelnor 1/35
The ethynodiol in Kelnor 1/35 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.
Major:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
Depression
Moderate:
estazolam
Estazolam has a moderate potential interaction with Depression.
Benzodiazepines depress the central nervous system and may cause or exacerbate mental depression and cause suicidal behavior and ideation. Episodes of mania and hypomania have also been reported in depressed patients treated with some of these agents. Therapy with benzodiazepines should be administered cautiously in patients with a history of depression or other psychiatric disorders. Patients should be monitored for any changes in mood or behavior. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Moderate:
Kelnor 1/35
The ethinyl estradiol and ethynodiol in Kelnor 1/35 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.
Diabetes Mellitus
Moderate:
Kelnor 1/35
The ethinyl estradiol and ethynodiol in Kelnor 1/35 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.
Drug Dependence
Major:
estazolam
Estazolam has a major potential interaction with Drug Dependence.
Benzodiazepines have the potential to cause dependence and abuse. Tolerance as well as physical and psychological dependence can develop, particularly after prolonged use and/or excessive dosages. However, abrupt cessation following continual use of as few as 6 weeks at therapeutic levels has occasionally precipitated withdrawal symptoms. Addiction- prone individuals, such as those with a history of alcohol or substance abuse, should be under careful surveillance when treated with benzodiazepines. It may be prudent to refrain from dispensing large quantities of medication to these patients. After prolonged use or if dependency is suspected, withdrawal of benzodiazepine therapy should be undertaken gradually using a dosage- tapering schedule. If withdrawal symptoms occur, temporary reinstitution of benzodiazepines may be necessary.
Fluid Retention
Moderate:
Kelnor 1/35
The ethinyl estradiol and ethynodiol in Kelnor 1/35 both have 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.
Gallbladder Disease
Moderate:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
Glaucoma/Intraocular Hypertension
Major:
estazolam
Estazolam has a major potential interaction with Glaucoma/Intraocular Hypertension.
The manufacturers consider the use of benzodiazepines to be contraindicated in patients with acute angle-closure glaucoma or untreated open-angle glaucoma. These agents do not possess anticholinergic activity but have very rarely been associated with increased intraocular pressure.
Heart Failure
Moderate:
Kelnor 1/35
The ethinyl estradiol and ethynodiol in Kelnor 1/35 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.
Hepatic Tumor
Major:
Kelnor 1/35
The ethinyl estradiol and ethynodiol in Kelnor 1/35 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.
High Blood Pressure
Major:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
High Cholesterol
Moderate:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
Moderate:
Kelnor 1/35
The ethynodiol in Kelnor 1/35 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.
History, Thrombotic/Thromboembolic Disorder
Major:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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 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.

Major:
Kelnor 1/35
The ethynodiol in Kelnor 1/35 has a major potential interaction with History, 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.

Hyperkinetic Syndrome of Childhood
Moderate:
estazolam
Estazolam has a moderate potential interaction with Hyperkinetic Syndrome of Childhood.
Paradoxical reactions, including excitability, irritability, aggressive behavior, agitation, nervousness, hostility, anxiety, sleep disturbances, nightmares and vivid dreams, have been reported with the use of benzodiazepines in psychiatric patients and pediatric patients with hyperactive aggressive disorders. Such patients should be monitored for signs of paradoxical stimulation during therapy with benzodiazepines. The manufacturers do not recommend the use of benzodiazepines for the treatment of psychosis.
Ischemic Heart Disease
Major:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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. 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.

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.
Liver Disease
Major:
Kelnor 1/35
The ethynodiol in Kelnor 1/35 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.
Moderate:
estazolam
Estazolam has a moderate potential interaction with Liver Disease.
Benzodiazepines are metabolized by the liver and undergo oxidative N-dealkylation to active metabolites that are substantially longer-acting than the parent compound. These metabolites then undergo further biotransformation before excretion by the kidney. Therapy with benzodiazepines should be administered cautiously at lower initial dosages in patients with impaired hepatic function. Agents that are converted to weakly active, short-acting, or inactive metabolites (such as oxazepam and temazepam) may be preferable in patients with hepatic impairment.
Moderate:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
Melasma
Moderate:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
Migraine
Major:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 has a major potential interaction with Migraine.
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.

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.
Moderate:
Kelnor 1/35
The ethinyl estradiol and ethynodiol in Kelnor 1/35 both have 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.
Neoplasia, Estrogen Dependent
Major:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
Pancreatitis
Moderate:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
Psychosis
Moderate:
estazolam
Estazolam has a moderate potential interaction with Psychosis.
Benzodiazepines depress the central nervous system and may cause or exacerbate mental depression and cause suicidal behavior and ideation. Episodes of mania and hypomania have also been reported in depressed patients treated with some of these agents. Therapy with benzodiazepines should be administered cautiously in patients with a history of depression or other psychiatric disorders. Patients should be monitored for any changes in mood or behavior. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Moderate:
estazolam
Estazolam has a moderate potential interaction with Psychosis.
Paradoxical reactions, including excitability, irritability, aggressive behavior, agitation, nervousness, hostility, anxiety, sleep disturbances, nightmares and vivid dreams, have been reported with the use of benzodiazepines in psychiatric patients and pediatric patients with hyperactive aggressive disorders. Such patients should be monitored for signs of paradoxical stimulation during therapy with benzodiazepines. The manufacturers do not recommend the use of benzodiazepines for the treatment of psychosis.
Pulmonary Impairment
Major:
estazolam
Estazolam has a major potential interaction with Pulmonary Impairment.
Benzodiazepines may cause respiratory depression and apnea, usually when given in high dosages and/or by intravenous administration. However, some patients may be susceptible at commonly used dosages, including the elderly, debilitated or severely ill patients, those receiving other CNS depressants, and those with limited ventilatory reserve, chronic pulmonary insufficiency or other respiratory disorders. Therapy with benzodiazepines should be administered cautiously in these patients. Appropriate monitoring and individualization of dosage are particularly important, and equipment for resuscitation should be immediately available if the parenteral route is used. Benzodiazepines, especially injectable formulations, should generally be avoided in patients with sleep apnea, severe respiratory insufficiency, or hypoxia.
Renal Dysfunction
Moderate:
estazolam
Estazolam has a moderate potential interaction with Renal Dysfunction.
Benzodiazepines are excreted by the kidneys and should be used with caution in patients with impaired renal function and end-stage kidney disease.
Moderate:
Kelnor 1/35
The ethinyl estradiol and ethynodiol in Kelnor 1/35 both have 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.
Respiratory Arrest
Major:
estazolam
Estazolam has a major potential interaction with Respiratory Arrest.
Benzodiazepines may cause respiratory depression and apnea, usually when given in high dosages and/or by intravenous administration. However, some patients may be susceptible at commonly used dosages, including the elderly, debilitated or severely ill patients, those receiving other CNS depressants, and those with limited ventilatory reserve, chronic pulmonary insufficiency or other respiratory disorders. Therapy with benzodiazepines should be administered cautiously in these patients. Appropriate monitoring and individualization of dosage are particularly important, and equipment for resuscitation should be immediately available if the parenteral route is used. Benzodiazepines, especially injectable formulations, should generally be avoided in patients with sleep apnea, severe respiratory insufficiency, or hypoxia.
Seizures
Major:
estazolam
Estazolam has a major potential interaction with Seizures.
The use of benzodiazepines in patients with seizure disorders may increase the incidence or precipitate the onset of generalized tonic-clonic seizures (grand mal). Appropriate anticonvulsant medication might need to be initiated or the dosage increased. Abrupt cessation of benzodiazepine therapy may precipitate seizures and other withdrawal symptoms, particularly after prolonged use and/or excessive dosages. Status epilepticus may occur in patients with a history of seizures withdrawn rapidly from benzodiazepine therapy. Following chronic administration, cessation of benzodiazepine therapy should occur gradually with incrementally reduced dosages. Patients should be advised not to discontinue medication without first consulting with the physician.
Moderate:
Kelnor 1/35
The ethinyl estradiol and ethynodiol in Kelnor 1/35 both have 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.
Smoking
Major:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
Thrombotic/Thromboembolic Disorder
Major:
Kelnor 1/35
The ethinyl estradiol in Kelnor 1/35 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.
Major:
Kelnor 1/35
The ethynodiol in Kelnor 1/35 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.
Thyroid Disease
Moderate:
Kelnor 1/35
The ethinyl estradiol and ethynodiol in Kelnor 1/35 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.
Weight Loss
Moderate:
estazolam
Estazolam has a moderate potential interaction with Weight Loss.
The plasma half-lives of benzodiazepines may be prolonged in obese patients, presumably due to increased distribution into fat. Marked increases in distribution (> 100%) have been reported for diazepam and midazolam, and moderate increases (25% to 100%) for alprazolam, lorazepam, and oxazepam. Therapy with benzodiazepines should be administered cautiously in obese patients, with careful monitoring of CNS status. Longer dosing intervals may be appropriate. When dosing by weight, loading doses should be based on actual body weight, while maintenance dose should be based on ideal body weight to avoid toxicity.
Minor:
Kelnor 1/35
The ethynodiol in Kelnor 1/35 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.
