Common use

Premarin is commonly prescribed for the management of moderate to severe vasomotor symptoms (hot flashes, night sweats) in menopausal and postmenopausal women. It is also used to treat symptoms of vulvar and vaginal atrophy, such as dryness, irritation, and painful intercourse. Additionally, it is indicated for the prevention of osteoporosis in postmenopausal women at high risk of fracture, particularly those who cannot tolerate or are not candidates for non-estrogen therapies. Treatment is typically initiated at the lowest effective dose for the shortest duration consistent with treatment goals and risks.

Dosage and direction

For moderate to severe vasomotor symptoms: The usual initial dose is 0.3 mg to 0.625 mg orally once daily. Dosage may be adjusted based on patient response.
For vulvar and vaginal atrophy: The usual dose is 0.3 mg to 0.625 mg orally daily, or 0.5 g of vaginal cream intravaginally once daily, cyclically (e.g., 3 weeks on, 1 week off).
For osteoporosis prevention: The usual dose is 0.3 mg to 0.625 mg orally once daily.
Take orally with or without food, at approximately the same time each day. For vaginal cream, use the applicator provided and follow instructions for proper administration. Do not exceed prescribed dosage. Regular reevaluation of therapy is recommended.

Precautions

Use the lowest effective dose for the shortest duration consistent with treatment goals. Regularly monitor blood pressure. Conduct baseline and periodic breast exams and mammograms. Perform regular gynecological examinations. Monitor for visual abnormalities, severe headaches, or signs of thromboembolic disorders. Use with caution in patients with asthma, epilepsy, migraine, diabetes, or cardiac or renal dysfunction. May cause fluid retention; use cautiously in patients with conditions that might be influenced by this factor. Discontinue use if jaundice occurs.

Contraindications

Known or suspected pregnancy. Undiagnosed abnormal genital bleeding. Known or suspected estrogen-dependent neoplasia. Active or history of deep vein thrombosis or pulmonary embolism. Active or recent arterial thromboembolic disease. Known liver dysfunction or disease. Known protein C, protein S, or antithrombin deficiency, or other known thrombophilic disorders. Hypersensitivity to any component of Premarin.

Possible side effects

Common side effects may include headache, breast tenderness or pain, nausea, abdominal cramps, bloating, vaginal bleeding or spotting, hair loss, and fluid retention. Less common but serious side effects can include deep vein thrombosis, pulmonary embolism, myocardial infarction, stroke, breast cancer, endometrial cancer, gallbladder disease, ovarian cancer, severe allergic reactions, visual abnormalities, and elevated blood pressure. Report any unusual symptoms to a healthcare provider promptly.

Drug interaction

May interact with CYP450 inducers (e.g., carbamazepine, phenytoin, rifampin) which can reduce estrogen levels. May decrease effectiveness of tamoxifen. Can alter thyroid hormone replacement requirements. May increase corticosteroid levels. Anticoagulants (e.g., warfarin) effect may be altered. May interact with other hormone therapies. Inform your healthcare provider of all medications, including over-the-counter drugs and supplements.

Missed dose

If a dose is missed, take it as soon as remembered. If it is near the time for the next dose, skip the missed dose and resume the regular schedule. Do not double the dose to catch up. For vaginal cream, follow the same guidelines based on the prescribed dosing schedule.

Overdose

Nausea and vomiting may occur. Vaginal bleeding has been reported. There is no specific antidote. Treatment should be symptomatic and supportive. In case of suspected overdose, seek immediate medical attention or contact a poison control center.
