Disease interactions

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

Abnormal Uterine Bleeding

Major:

Progynova TS

The estradiol in Progynova TS 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.

Adrenal Insufficiency

Major:

Armour Thyroid

The thyroid desiccated in Armour Thyroid has a major potential interaction with Adrenal Insufficiency.

The use of thyroid hormones is contraindicated in patients with uncorrected adrenal insufficiency. Thyroid hormones increase tissue demand for adrenocortical hormones and may precipitate acute adrenal crisis. In patients with controlled adrenal insufficiency or other endocrine disorders, therapy for these concomitant disorders may need to be adjusted following thyroid replacement, since hypothyroidism often obscure or diminish the signs and symptoms of these conditions. Clinical monitoring of thyroid and adrenal function as well as any other appropriate endocrine function is recommended during thyroid hormone therapy.

Angioedema

Moderate:

Progynova TS

The estradiol in Progynova TS 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:

Progynova TS

The estradiol in Progynova TS 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:

Progynova TS

The estradiol in Progynova TS 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:

Progynova TS

The estradiol in Progynova TS 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 Insipidus

Moderate:

Armour Thyroid

The thyroid desiccated in Armour Thyroid has a moderate potential interaction with Diabetes Insipidus.

Since hypothyroidism often obscure or diminish the signs and symptoms of endocrine disorders such as diabetes mellitus or diabetes insipidus, thyroid replacement therapy may aggravate the intensity of symptoms associated with these conditions. Patients with endocrine disorders should be monitored more closely during thyroid hormone therapy, and their medication regimen adjusted accordingly. If thyroid medication is later discontinued, a downward readjustment of insulin or oral hypoglycemic agent may be necessary in patients with diabetes mellitus to avoid hypoglycemia.

Diabetes Mellitus

Moderate:

Armour Thyroid

The thyroid desiccated in Armour Thyroid has a moderate potential interaction with Diabetes Mellitus.

Since hypothyroidism often obscure or diminish the signs and symptoms of endocrine disorders such as diabetes mellitus or diabetes insipidus, thyroid replacement therapy may aggravate the intensity of symptoms associated with these conditions. Patients with endocrine disorders should be monitored more closely during thyroid hormone therapy, and their medication regimen adjusted accordingly. If thyroid medication is later discontinued, a downward readjustment of insulin or oral hypoglycemic agent may be necessary in patients with diabetes mellitus to avoid hypoglycemia.

Moderate:

Progynova TS

The estradiol in Progynova TS 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:

Progynova TS

The estradiol in Progynova TS 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:

Progynova TS

The estradiol in Progynova TS 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 Disease

Major:

Armour Thyroid

The thyroid desiccated in Armour Thyroid has a major potential interaction with Heart Disease.

Thyroid hormones cause increases in myocardial contractility and heart rate as a result of increased metabolic demands and oxygen consumption. Therapy with thyroid hormones should be administered cautiously and initiated at reduced dosages in patients with cardiovascular disorders such as angina, coronary artery disease, and hypertension. Clinical monitoring of cardiovascular function is recommended. If chest pain or exacerbation of cardiovascular disease occurs, the dosage of thyroid hormone should be reduced, even at the expense of achieving euthyroid state. Thyroid hormones should not be administered to patients with an acute myocardial infarction that is not complicated by hypothyroidism.

Heart Failure

Moderate:

Progynova TS

The estradiol in Progynova TS 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:

Armour Thyroid

The thyroid desiccated in Armour Thyroid has a major potential interaction with High Blood Pressure.

Thyroid hormones cause increases in myocardial contractility and heart rate as a result of increased metabolic demands and oxygen consumption. Therapy with thyroid hormones should be administered cautiously and initiated at reduced dosages in patients with cardiovascular disorders such as angina, coronary artery disease, and hypertension. Clinical monitoring of cardiovascular function is recommended. If chest pain or exacerbation of cardiovascular disease occurs, the dosage of thyroid hormone should be reduced, even at the expense of achieving euthyroid state. Thyroid hormones should not be administered to patients with an acute myocardial infarction that is not complicated by hypothyroidism.

Major:

Progynova TS

The estradiol in Progynova TS 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:

Progynova TS

The estradiol in Progynova TS 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.

Thyroid Disease

Moderate:

Progynova TS

The estradiol in Progynova TS 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.
