Interactions between Estratest H.S. and Interferon beta-1a

The esterified estrogens in Estratest H.S. 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 esterified estrogens in Estratest H.S. 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.

Interferon beta-1a has a major potential interaction with Arrhythmia.

Hypertension, arrhythmias, angina, myocardial infarction, cardiomyopathy, and congestive heart failure have been reported during interferon therapy. Therapy with interferons should be administered with caution in patients with compromised cardiac function.

The esterified estrogens in Estratest H.S. 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 methylTESTOSTERone in Estratest H.S. has a major potential interaction with Benign Prostatic Hyperplasia.

The use of androgenic anabolic steroids is contraindicated for male patients with carcinoma of the breast or prostate. Circulating androgens can be converted in peripheral tissues to estrogens and dihydrotestosterone, which may act as promoters of tumor growth in the breast and prostate, respectively. Likewise, androgenic agents may cause enlargement of the prostate and should be used cautiously in patients with or predisposed to prostatic hypertrophy.

The methylTESTOSTERone in Estratest H.S. has a major potential interaction with Bleeding Disorder.

Androgenic anabolic steroids may cause suppression of clotting factors II, V, VII, and X, and an increase in prothrombin time. Androgen therapy should be administered cautiously in patients with bleeding disorders.

The esterified estrogens in Estratest H.S. 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 methylTESTOSTERone in Estratest H.S. has a major potential interaction with Breast Cancer.

When treated with androgenic anabolic steroids, patients with metastatic breast cancer may develop hypercalcemia due to osteolysis. Frequent determination of urine and serum calcium levels is recommended during therapy with androgenic agents. If hypercalcemia occurs, therapy should be stopped. The development of hypercalcemia may indicate progression of metastases to the bone.

The methylTESTOSTERone in Estratest H.S. has a major potential interaction with Breast Cancer, Male.

The use of androgenic anabolic steroids is contraindicated for male patients with carcinoma of the breast or prostate. Circulating androgens can be converted in peripheral tissues to estrogens and dihydrotestosterone, which may act as promoters of tumor growth in the breast and prostate, respectively. Likewise, androgenic agents may cause enlargement of the prostate and should be used cautiously in patients with or predisposed to prostatic hypertrophy.

Interferon beta-1a has a major potential interaction with Cardiovascular Conditions and Disorders.

The esterified estrogens in Estratest H.S. 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.

Interferon beta-1a has a major potential interaction with Depression.

Interferons (alfa or beta) can induce depression and suicidal behavior. Suicidal attempts and suicides have been reported. Therapy with interferons (alfa or beta) should be administered cautiously to patients with or predisposed to mental depression. Clinical monitoring of psychological status is recommended.

The methylTESTOSTERone in Estratest H.S. has a moderate potential interaction with Diabetes Mellitus.

The metabolic effects of androgenic anabolic steroids may lower blood glucose. Decreased glucose tolerance and increased insulin resistance have also been reported. Patients with diabetes mellitus should be monitored more closely during therapy with androgenic agents, and their antidiabetic regimen adjusted accordingly.

The esterified estrogens in Estratest H.S. 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 methylTESTOSTERone in Estratest H.S. has a major potential interaction with Fluid Retention.

Androgenic anabolic steroids may cause sodium and water 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 fluid overload or are at risk for developing edema. The manufacturers consider the use of androgenic agents to be contraindicated in patients with severe cardiac, renal and/or hepatic dysfunction.

The esterified estrogens in Estratest H.S. has 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 esterified estrogens in Estratest H.S. 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 methylTESTOSTERone in Estratest H.S. has a major potential interaction with High Cholesterol.

Androgenic anabolic steroids may adversely affect serum lipids, including lowering HDL and elevating LDL levels. These changes can be marked, particularly with the 17-alpha-alkyl derivatives (i.e., fluoxymesterone, methyltestosterone, oxandrolone, oxymetholone, and stanozolol), and may significantly impact the risk of atherosclerosis and coronary artery disease. Patients with preexisting hyperlipoproteinemia may require closer monitoring during therapy with androgenic agents, and adjustments made accordingly in their lipid-lowering regimen. Androgen therapy should be administered cautiously in patients with coronary artery disease or a history of ischemic heart disease.

The esterified estrogens in Estratest H.S. 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.

Interferon beta-1a has a major potential interaction with Liver Disease.

Severe hepatic injury, including hepatitis, autoimmune hepatitis, cases of hepatic failure and asymptomatic transient increases in the concentrations of serum transaminases, have been reported in patients treated with beta interferons. In some cases, these events have occurred in the presence of other drugs that have been associated with hepatic injury. The potential risk of these agents used in combination with known hepatotoxic drugs or other products (e.g., alcohol) should be considered before starting therapy, or before starting hepatotoxic drugs. Patients should be monitored for signs of hepatic injury, including the regular monitoring of liver function tests, and discontinuation of therapy should be considered if serum transaminase levels significantly increase or if hepatic injury occurs.

The esterified estrogens in Estratest H.S. 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 esterified estrogens in Estratest H.S. 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 methylTESTOSTERone in Estratest H.S. has a minor potential interaction with Underactive Thyroid.

When androgenic anabolic steroids are used in patients with thyroid disorders, clinicians should be aware that these agents may affect thyroid function tests.
