Drug interactions

Moderate drug interactions

Moderate:

estradiol bosentan

Applies to: Femsept (estradiol) and bosentan

Bosentan may reduce the blood levels and effects of estradiol. If you are using low-dose oral contraceptives, you may have an increased risk of breakthrough bleeding and unintended pregnancy. You should discuss the use of alternative or additional methods of birth control with your healthcare provider. If you take hormone replacement for menopause, notify your doctor if your medication is no longer controlling your symptoms or you experience abnormal bleeding. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Disease interactions

26 potential interactions Applies to: 23 conditions, including High Blood Pressure, High Cholesterol, Migraine, Heart Failure, and Asthma.

Abnormal Uterine Bleeding

Major:

Femsept

The estradiol in Femsept 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.

Anemia

Moderate:

bosentan

Bosentan has a moderate potential interaction with Anemia.

Clinical studies have shown that most endothelin receptor antagonists decrease hemoglobin concentration and hematocrit levels. There are some postmarketing reports of anemia cases which needed blood transfusion. Hemoglobin and hematocrit levels should be measured prior to treatment initiation and should be monitored periodically thereafter. Initiation of therapy is not recommended in patients with clinically significant anemia.

Angioedema

Moderate:

Femsept

The estradiol in Femsept 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.

Asthma

Moderate:

Femsept

The estradiol in Femsept 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.

Breast Cancer

Major:

Femsept

The estradiol in Femsept 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:

Femsept

The estradiol in Femsept 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.

Diabetes Mellitus

Moderate:

Femsept

The estradiol in Femsept 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.

Fluid Retention

Moderate:

Femsept

The estradiol in Femsept 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.

Gallbladder Disease

Moderate:

Femsept

The estradiol in Femsept 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.

Heart Failure

Moderate:

bosentan

Bosentan has a moderate potential interaction with Heart Failure.

Peripheral edema and fluid retention are known clinical consequences of pulmonary hypertension and also known effects of endothelin receptor antagonists. Caution and monitoring is recommended if these agents are used in patients with underlying left ventricular dysfunction or underlying heart failure, as they have an increased risk for developing significant fluid retention that may need treatment or require discontinuation.

Moderate:

Femsept

The estradiol in Femsept 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.

High Blood Pressure

Major:

Femsept

The estradiol in Femsept 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:

Femsept

The estradiol in Femsept 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.

History, Thrombotic/Thromboembolic Disorder

Major:

Femsept

The estradiol in Femsept 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. 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.

Hypoparathyroidism

Moderate:

Femsept

The estradiol in Femsept 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.

Ischemic Heart Disease

Major:

Femsept

The estradiol in Femsept 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. 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.

Liver Disease

Major:

bosentan

Bosentan has a major potential interaction with Liver Disease.

Endothelin receptor antagonists (ERAs) have been associated with aminotransferase elevations, hepatotoxicity, and cases of liver failure. Hepatic function should be assessed before treatment initiation and closely monitored during treatment. Therapy should be discontinued if aminotransferase elevations are accompanied by increases in bilirubin, or clinical symptoms of hepatotoxicity such as nausea, vomiting, fever, abdominal pain or jaundice. Treatment should be avoided in patients with elevated aminotransferases at baseline as monitoring for hepatotoxicity may be more difficult. In general, the use of ERAs is not recommended for patients with moderate to severe hepatic impairment.

Moderate:

Femsept

The estradiol in Femsept 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.

Migraine

Major:

Femsept

The estradiol in Femsept 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.

Thyroid Disease

Moderate:

Femsept

The estradiol in Femsept 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.
