Edit list (add/remove drugs)

Interactions between your drugs

Moderate

estradiol tirzepatide

Applies to: Progynova (estradiol) and tirzepatide

Tirzepatide may affect the blood levels and effects of oral contraceptives, which contain hormones such as estradiol. This may increase the risk of breakthrough bleeding and unintended pregnancy. Alternative, non-oral methods of birth control should be used, or add another method of birth control (such as condoms) to the oral contraceptive for 4 weeks after starting tirzepatide and for 4 weeks each time after the dose of tirzepatide is increased to avoid unintended pregnancy. Talk to your gynecologist or other healthcare professional if you have any questions or concerns, and for help in selecting an effective method of birth control that is best for you. 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.

Drug and food/lifestyle interactions

Moderate

tirzepatide food/lifestyle

Applies to: tirzepatide

Tirzepatide may affect the absorption of other medications that you take by mouth. In some cases, this may affect how well and/or how fast those medications work, or it may make no difference. Talk to a healthcare provider if you have any questions or concerns, and contact your doctor if your symptoms worsen or your condition changes. 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.

Minor

estradiol food/lifestyle

Applies to: Progynova (estradiol)

Information for this minor interaction is available on the professional version.

Disease interactions

Major

estradiol Abnormal Uterine Bleeding

Applies to: Abnormal Uterine Bleeding

The use of estrogens is contraindicated in patients with undiagnosed, abnormal vaginal bleeding. Prolonged (> 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.

Major

estradiol Breast Cancer

Applies to: 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.

Major

estradiol Cerebral Vascular Disorder

Applies to: 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.

Major

estradiol Hepatic Tumor

Applies to: 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.

Major

estradiol History - Thrombotic/Thromboembolic Disorder

Applies to: 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.

Major

estradiol Hypertension

Applies to: Hypertension

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.

Major

estradiol Ischemic Heart Disease

Applies to: 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.

Major

estradiol Migraine

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

tirzepatide Multiple Endocrine Neoplasia Type II

Applies to: Multiple Endocrine Neoplasia Type II

Tirzepatide is contraindicated in patients with a personal or family history of medullary thyroid carcinoma (MTC) and in patients with multiple endocrine neoplasia syndrome type 2. Patients with elevated serum calcitonin or thyroid nodules noted on physical examination or neck imaging should be further evaluated. Patients should be counseled regarding the potential risk for MTC with the use of tirzepatide and should be informed of symptoms of thyroid tumors.

Major

estradiol Neoplasia -- Estrogen Dependent

Applies to: 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.

Major

estradiol Thrombotic/Thromboembolic Disorder

Applies to: 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.

Major

tirzepatide Thyroid Tumor

Applies to: Thyroid Tumor

Tirzepatide is contraindicated in patients with a personal or family history of medullary thyroid carcinoma (MTC) and in patients with multiple endocrine neoplasia syndrome type 2. Patients with elevated serum calcitonin or thyroid nodules noted on physical examination or neck imaging should be further evaluated. Patients should be counseled regarding the potential risk for MTC with the use of tirzepatide and should be informed of symptoms of thyroid tumors.

Moderate

estradiol Angioedema

Applies to: Angioedema

The use of exogenous estrogens may induce or exacerbate symptoms of angioedema, particularly in women with hereditary angioedema. Close monitoring is recommended when prescribing these agents to patients predisposed to angioedema.

Moderate

estradiol Asthma

Applies to: 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.

Moderate

estradiol Congestive Heart Failure

Applies to: Congestive 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.

Moderate

tirzepatide Dehydration

Applies to: Dehydration

Tirzepatide has been associated with gastrointestinal adverse reactions (including nausea, vomiting, diarrhea); such events may lead to dehydration, which could cause acute kidney injury if severe. There have been postmarketing reports of acute kidney injury and worsening of chronic renal failure (which may sometimes require hemodialysis) in patients treated with glucagon-like peptide-1 (GLP-1) receptor agonists; some of these events were reported in patients without known underlying renal disease, and most of the reported cases occurred in patients who experienced nausea, vomiting, diarrhea, or dehydration. Renal function should be monitored when starting or escalating doses of tirzepatide in patients with renal dysfunction reporting severe gastrointestinal adverse reactions. No dose adjustment is recommended for patients with renal dysfunction.

Moderate

estradiol Diabetes Mellitus

Applies to: 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.

Moderate

tirzepatide Diabetic Retinopathy

Applies to: Diabetic Retinopathy

Tirzepatide has not been studied in patients with nonproliferative diabetic retinopathy requiring acute therapy, proliferative diabetic retinopathy, or diabetic macular edema; caution is recommended in these patients. Rapid improvement in glucose control has been associated with a temporary worsening of diabetic retinopathy. Patients with history of diabetic retinopathy should be monitored for progression of diabetic retinopathy.

Moderate

tirzepatide Diarrhea

Applies to: Diarrhea

Tirzepatide has been associated with gastrointestinal adverse reactions (including nausea, vomiting, diarrhea); such events may lead to dehydration, which could cause acute kidney injury if severe. There have been postmarketing reports of acute kidney injury and worsening of chronic renal failure (which may sometimes require hemodialysis) in patients treated with glucagon-like peptide-1 (GLP-1) receptor agonists; some of these events were reported in patients without known underlying renal disease, and most of the reported cases occurred in patients who experienced nausea, vomiting, diarrhea, or dehydration. Renal function should be monitored when starting or escalating doses of tirzepatide in patients with renal dysfunction reporting severe gastrointestinal adverse reactions. No dose adjustment is recommended for patients with renal dysfunction.

Moderate

estradiol Fluid Retention

Applies to: 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.

Moderate

estradiol Gallbladder Disease

Applies to: 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.

Moderate

tirzepatide Gastroparesis

Applies to: Gastroparesis

Use of tirzepatide has been associated with gastrointestinal adverse reactions (sometimes severe). Because tirzepatide has not been studied in patients with severe gastrointestinal disease (including severe gastroparesis), it is not recommended in these patients.

Moderate

estradiol Hyperlipidemia

Applies to: Hyperlipidemia

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

estradiol Hypoparathyroidism

Applies to: 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.

Moderate

estradiol Liver Disease

Applies to: 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.

Moderate

estradiol Migraine

Applies to: 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.

Moderate

tirzepatide Pancreatitis

Applies to: Pancreatitis

Acute pancreatitis (including fatal and nonfatal hemorrhagic or necrotizing pancreatitis) has been observed in patients treated with glucagon-like peptide-1 (GLP-1) receptor agonists; acute pancreatitis has been reported in patients treated with tirzepatide in clinical trials. Tirzepatide has not been studied in patients with history of pancreatitis; it is unknown if such patients are at higher risk of developing pancreatitis on tirzepatide. After initiation of tirzepatide, patients should be observed carefully for signs/symptoms of pancreatitis (including persistent severe abdominal pain [sometimes radiating to the back], with or without vomiting); if pancreatitis is suspected, tirzepatide should be discontinued and appropriate management should be started.

Moderate

tirzepatide Renal Dysfunction

Applies to: Renal Dysfunction

Tirzepatide has been associated with gastrointestinal adverse reactions (including nausea, vomiting, diarrhea); such events may lead to dehydration, which could cause acute kidney injury if severe. There have been postmarketing reports of acute kidney injury and worsening of chronic renal failure (which may sometimes require hemodialysis) in patients treated with glucagon-like peptide-1 (GLP-1) receptor agonists; some of these events were reported in patients without known underlying renal disease, and most of the reported cases occurred in patients who experienced nausea, vomiting, diarrhea, or dehydration. Renal function should be monitored when starting or escalating doses of tirzepatide in patients with renal dysfunction reporting severe gastrointestinal adverse reactions. No dose adjustment is recommended for patients with renal dysfunction.

Moderate

estradiol Renal Dysfunction

Applies to: 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.

Moderate

estradiol Seizures

Applies to: 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.

Moderate

estradiol Thyroid Disease

Applies to: 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. 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. Patients on thyroid replacement therapy may require higher doses of thyroid hormone and appropriate monitoring.

Moderate

tirzepatide Vomiting

Applies to: Vomiting

Tirzepatide has been associated with gastrointestinal adverse reactions (including nausea, vomiting, diarrhea); such events may lead to dehydration, which could cause acute kidney injury if severe. There have been postmarketing reports of acute kidney injury and worsening of chronic renal failure (which may sometimes require hemodialysis) in patients treated with glucagon-like peptide-1 (GLP-1) receptor agonists; some of these events were reported in patients without known underlying renal disease, and most of the reported cases occurred in patients who experienced nausea, vomiting, diarrhea, or dehydration. Renal function should be monitored when starting or escalating doses of tirzepatide in patients with renal dysfunction reporting severe gastrointestinal adverse reactions. No dose adjustment is recommended for patients with renal dysfunction.
