Premarin 0.625 Mg Tablet (28 Tab)

PREMARIN 0.625 MG TABLET

PREMARIN 0.625 mg Tablet, manufactured by Pfizer Limited, is a widely recognized form of hormone replacement therapy (HRT) containing conjugated estrogens.

Composition The active ingredient in PREMARIN 0.625 mg Tablet is 0.625 mg of conjugated estrogens. This is a mixture of estrogens primarily obtained from natural sources, occurring as sodium salts of water-soluble estrogen sulfates, including sodium estrone sulfate and sodium equilin sulfate. Inactive ingredients include calcium phosphate tribasic, lactose monohydrate, sucrose, microcrystalline cellulose, hypromellose, magnesium stearate, and polyethylene glycol. The 0.625 mg tablet is maroon in color.

Uses PREMARIN 0.625 mg Tablet is prescribed for various medical conditions, predominantly:

• Alleviating moderate to severe vasomotor symptoms (such as hot flashes and sweating) and vulvar and vaginal atrophy associated with menopause.
• Prevention and management of postmenopausal osteoporosis in women at high risk of fractures.
• Treatment of hypoestrogenism resulting from conditions like hypogonadism, castration, or primary ovarian failure.
• Palliative treatment for certain advanced stages of breast cancer in appropriately selected women and men, and advanced androgen-dependent carcinoma of the prostate.

Dosage and Administration PREMARIN 0.625 mg tablets should be taken orally, exactly as directed by a healthcare professional. Tablets should be swallowed whole and not be broken, crushed, chewed, or dissolved. For menopausal symptoms and osteoporosis prevention, a common starting dose is 0.3 mg or 0.625 mg daily. The medication may be administered continuously or in cyclic regimens, such as 3 weeks on and 1 week off. The lowest effective dose for the shortest duration consistent with treatment goals should always be used. For women with an intact uterus, a progestogen is generally co-administered to reduce the risk of endometrial cancer.

Side Effects Common side effects include headache, breast pain or tenderness, irregular vaginal bleeding or spotting, abdominal cramps or bloating, nausea, vomiting, and hair loss.

Serious side effects that require immediate medical attention include symptoms of blood clots (e.g., chest pain, shortness of breath, leg pain or swelling), stroke (e.g., sudden severe headache, numbness/weakness on one side of the body, vision changes), heart attack, yellowing of the skin or eyes (jaundice), and breast lumps. Estrogen-only therapy can increase the risk of uterine cancer if the uterus is intact, and there are increased risks of breast cancer, ovarian cancer, heart disease, stroke, blood clots, gallbladder disease, and dementia (in women 65 years or older) with estrogen therapy.

Precautions PREMARIN should not be used for the prevention of heart disease, heart attacks, strokes, or dementia. Patients should inform their doctor of any personal or family history of breast cancer and regularly perform breast self-examinations. Any unusual vaginal bleeding should be reported promptly. It is important to disclose all medicines and supplements, as some can interact with conjugated estrogens. Caution is advised for individuals with existing conditions such as heart or kidney problems, epilepsy, asthma, fibroids, or a history of blood clots. PREMARIN is contraindicated during pregnancy and breastfeeding. Diabetic patients and those with hypertriglyceridemia should be closely monitored.

Storage PREMARIN tablets should be stored in their blister pack at a controlled room temperature, typically between 20° to 25°C (68° to 77°F), with permitted excursions to 15° to 30°C (59° to 86°F). Keep the medicine in a cool, dry place, below 25°C, away from excessive heat, moisture, and direct sunlight. It should be kept out of the reach of children and pets.

Here are some frequently asked questions about PREMARIN 0.625 MG TABLET:

What is PREMARIN 0.625 MG TABLET used for?

PREMARIN 0.625 MG TABLET is primarily used to treat moderate to severe hot flashes and other symptoms of menopause, such as vulvar and vaginal atrophy. It is also used to prevent postmenopausal osteoporosis and to treat low estrogen levels due to conditions like hypogonadism, castration, or primary ovarian failure. Additionally, it may be used for the palliation of certain advanced stages of breast cancer in women and men, and advanced androgen-dependent carcinoma of the prostate.

How does PREMARIN 0.625 MG TABLET work?

PREMARIN contains conjugated estrogens, which are a mixture of female hormones. It works by replacing the estrogen that your body naturally produces, which decreases during menopause. Estrogens play a vital role in the development and maintenance of the female reproductive system and secondary sexual characteristics. By supplementing estrogen, PREMARIN helps alleviate symptoms caused by its deficiency.

What is the usual dosage for PREMARIN 0.625 MG TABLET?

For menopause symptoms and osteoporosis prevention, a typical starting dosage is 0.3 mg once daily, but 0.625 mg once daily is also common and often the minimum effective dose for preventing osteoporosis. The tablets can be taken continuously (every day) or in cycles (e.g., 25 days on, followed by 5 days off, or 3 weeks on and 1 week off). Your doctor will determine the lowest effective dose for the shortest duration consistent with your treatment goals, and the dosage may be adjusted based on your individual response. If you have a uterus, your doctor will likely prescribe a progestin along with PREMARIN to help reduce the risk of endometrial cancer.

What are the possible side effects of PREMARIN 0.625 MG TABLET?

Common side effects may include headache, breast pain or tenderness, nausea, vomiting, abdominal pain or cramps, bloating, changes in weight or appetite, vaginal discharge, irritation or itching, changes in menstrual periods, decreased sex drive, dizziness, feeling tired, nervousness, increased hair growth, or problems with contact lenses.

Serious side effects can occur, including an increased risk of uterine cancer (if estrogen is taken alone without a progestin), stroke, blood clots (deep vein thrombosis, pulmonary embolism), heart attack, breast cancer, and probable dementia (especially in women aged 65 or older). Report any unusual vaginal bleeding, severe headache, sudden vision loss, slurred speech, chest pain, shortness of breath, pain or warmth in one or both legs, yellowing of the skin or eyes (jaundice), breast lumps, severe abdominal pain, persistent nausea or vomiting, memory problems, confusion, or unusual behavior to your doctor immediately.

Is PREMARIN 0.625 MG TABLET safe during pregnancy or breastfeeding?

No, PREMARIN is not indicated for use during pregnancy and should not be used if you are pregnant or think you may be pregnant. If you become pregnant while taking this medication, stop treatment immediately and contact your doctor.

For breastfeeding mothers, estrogens can pass into breast milk and may reduce the quantity and quality of milk produced. Therefore, PREMARIN is generally not recommended during breastfeeding.

Can PREMARIN 0.625 MG TABLET be taken with other medications?

PREMARIN can interact with several other medications and substances.

• Reduced effectiveness of Premarin: Medications and herbal supplements that are CYP3A4 inducers, such as St. John's Wort, phenobarbital, carbamazepine, and rifampin, can lower estrogen levels, potentially making PREMARIN less effective.
• Increased side effects of Premarin: CYP3A4 inhibitors, including certain antibiotics (e.g., erythromycin, clarithromycin), antifungals (e.g., ketoconazole, itraconazole), ritonavir, and grapefruit juice, can increase estrogen levels and may lead to more side effects.
• Other interactions: Be sure to inform your doctor if you are taking blood thinners (like warfarin), thyroid medications, or insulin/oral diabetes medicines, as adjustments may be necessary. Always tell your doctor about all prescription and over-the-counter medications, vitamins, and herbal products you are using.

What precautions should be taken while using PREMARIN 0.625 MG TABLET?

It is crucial to report any unusual vaginal bleeding to your doctor right away. PREMARIN is not for preventing heart disease, heart attacks, strokes, or dementia. Use the lowest effective dose for the shortest possible duration. Regular medical check-ups, including pelvic exams, breast exams, and mammograms, are important while on this medication.

Do not take PREMARIN if you have unusual vaginal bleeding, certain cancers (like breast or estrogen-dependent cancer), a history of stroke, heart attack, blood clots, or liver problems. Also, avoid smoking while on estrogen therapy, as it significantly increases the risk of serious cardiovascular events.

What happens if a dose of PREMARIN 0.625 MG TABLET is missed?

If you miss a dose of PREMARIN, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.

How should PREMARIN 0.625 MG TABLET be stored?

PREMARIN 0.625 MG TABLET should be stored at room temperature, typically between 20° to 25°C (68° to 77°F), and can tolerate brief excursions between 15° to 30°C (59° to 86°F). Keep the medicine in its closed container, away from heat, moisture, and direct light. It is important to keep all medications out of the reach of children.
