Drug interactions
Major drug interactions
Major:
estradiol zanubrutinib
Applies to: Femsept (estradiol) and zanubrutinib
Zanubrutinib may reduce the blood levels of estradiol, which may make it less reliable as a form of birth control. Alternative and/or additional methods of birth control should be used during treatment with zanubrutinib and for at least one week after zanubrutinib therapy to avoid unintended pregnancy. This is particularly important because zanubrutinib may cause harm in the unborn child. Talk to your gynecologist or other healthcare professional 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.

Major food/lifestyle interactions
Major:
zanubrutinib Food/Lifestyle
Applies to: zanubrutinib
Grapefruit juice and Seville orange juice can increase the blood levels of zanubrutinib. This may increase the risk of serious side effects such as hemorrhage, development of other cancers, abnormal heart rhythm, liver injury, and impaired bone marrow function resulting in low numbers of different types of blood cells. You may also be more likely to develop anemia, bleeding problems, or infections due to low blood cell counts, as well as rash, diarrhea, constipation, or cough. You should avoid the consumption of grapefruit, grapefruit juice, Seville oranges (a citrus relative of the grapefruit), and Seville orange juice during treatment with zanubrutinib. Otherwise, you may need a dose adjustment, interruption, or more frequent monitoring by your doctor to safely use this medication. You should take the medication at approximately the same time(s) every day to maintain consistent blood levels and effects. Contact your doctor if you experience side effects or if your condition changes during treatment with zanubrutinib. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. 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
31 potential interactions Applies to: 27 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.
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.
Bleeding Associated with Coagulation Defect
Moderate:
zanubrutinib
Zanubrutinib has a moderate potential interaction with Bleeding Associated with Coagulation Defect.
Fatal and serious hemorrhage have occurred in patients with hematological malignancies treated with zanubrutinib. Bleeding has occurred in patients with and without concomitant antiplatelet or anticoagulation therapy; this may be considered for patients with bleeding problems, patients who have had recent surgery, or patients who plan to have surgery. Coadministration of zanubrutinib with antiplatelet or anticoagulant medications may further increase the risk of hemorrhage. It is recommended to monitor for signs/symptoms of bleeding and to discontinue zanubrutinib if intracranial hemorrhage of any grade occurs. The benefit-risk of withholding zanubrutinib for 3 to 7 days before and after surgery (depending on the type of surgery and the risk of bleeding) should be considered.
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 Disease
Moderate:
zanubrutinib
Zanubrutinib has a moderate potential interaction with Heart Disease.
Serious cardiac arrhythmias (including atrial fibrillation and atrial flutter) have been reported with zanubrutinib. Patients with cardiac risk factors, hypertension, and acute infections may be at increased risk of cardiac arrhythmias. It is recommended to monitor for signs/symptoms of cardiac arrhythmias, manage appropriately, and consider the risks and benefits of continued treatment with zanubrutinib.
Heart Failure
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.
Hemodialysis
Moderate:
zanubrutinib
Zanubrutinib has a moderate potential interaction with Hemodialysis.
The effect of dialysis on zanubrutinib pharmacokinetics is unknown. Patients on dialysis should be monitored for zanubrutinib adverse reactions. No dosage modification is recommended in patients with mild, moderate, or severe renal dysfunction (CrCl at least 15 mL/min, estimated by Cockroft-Gault).
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.
Moderate:
zanubrutinib
Zanubrutinib has a moderate potential interaction with High Blood Pressure.
Serious cardiac arrhythmias (including atrial fibrillation and atrial flutter) have been reported with zanubrutinib.
