Conjugated estrogens (Premarin): uses in menopause, price in the Philippines

Prices checked October 2026. For example monthly totals, use the cost calculator.

Conjugated estrogens replace the estrogen your ovaries stop making. They ease hot flashes, night sweats and vaginal dryness, and help prevent bone loss.

From the US label (the Philippine leaflet may differ):

• It is taken by mouth once a day.
• For hot flashes, the label lists a starting dose of 0.3 mg daily, adjusted by the doctor according to response. Strengths of 0.3 mg, 0.45 mg, 0.625 mg and higher exist abroad. Only 0.625 mg was found in PH retail.
• Your doctor reviews the dose and the need to continue at follow-up.

With a uterus, a progestogen is added: micronized progesterone, dydrogesterone or medroxyprogesterone acetate. In the WHI trial, conjugated estrogens 0.625 mg were combined with medroxyprogesterone acetate 2.5 mg daily (US label).

Without a uterus, estrogen alone is usually enough. In the WHI estrogen-alone arm, conjugated estrogens 0.625 mg were not linked to a higher risk of invasive breast cancer (relative risk 0.80), though stroke and blood clot risks were higher (US label). See Nakaka-cancer ba ang HRT?

These are label facts, not your dose. Your doctor decides.

Estrogen tablets pass through the liver first, which affects clotting factors. The Menopause Society 2022 says transdermal routes (gel or patch) and lower doses may reduce the risk of blood clots and stroke. So many doctors now prefer estradiol gel, especially for women with a higher risk of blood clots.

Tablets still have a place. Some women prefer a pill to a daily gel, and conjugated estrogens are one of the lower-cost estrogens on the shelf. This is a choice to make with your doctor, with your own risks in mind.

The US label says conjugated estrogens should not be used if you have or had (the Philippine leaflet may differ):

• Breast cancer, or it is suspected
• Another estrogen-dependent cancer
• Genital or vaginal bleeding that has not been checked
• A blood clot in a leg or lung, or a known clotting disorder (such as protein C, protein S or antithrombin deficiency)
• A stroke or heart attack
• Liver disease
• A serious allergic reaction to Premarin

Tell your doctor about high blood pressure, migraines, diabetes, gallbladder disease, high triglycerides or thyroid medicine. The label warns that estrogen can raise triglycerides, makes gallbladder disease more likely, can worsen diabetes and migraine, and may change the thyroid dose you need.

The most common ones in the US label include:

• Breast pain
• Nausea, stomach pain or wind
• Headache and back pain
• Vaginal bleeding or spotting
• Vaginal discharge
• Trouble sleeping or low mood

These often settle in the first months.

In November 2025, the US FDA moved to remove the boxed warnings for heart disease, breast cancer and probable dementia from menopause hormone labels, including conjugated estrogens. The endometrial cancer boxed warning stays for systemic estrogen-alone products, which is why a progestogen is still needed with a uterus. A generic version of Premarin was approved in the US the same day (RAPS).

Philippine product leaflets may not reflect this yet.

Bring these to your consult. A short list helps when appointments are rushed:

• "Is a tablet right for me, or would estradiol gel be a better fit given my blood pressure, weight or migraines?"
• "Which progestogen will I take with it, and for how many days a month?"
• "Is the 0.625 mg strength the dose you want, or should I start lower if a lower strength can be found?"
• "What bleeding pattern should I expect, and when should I call you?"
• "When is my first follow-up, and which tests do I need before then?"

A symptom diary kept for two to four weeks before the visit makes the answers more useful. Our talk to your doctor page has a Taglish script.

• Estradiol gel (Oestrogel): skin route, ₱1,185.50 per 80 g pump pack (Watsons).
• Tibolone: one tablet, no separate progestogen, after periods have stopped for a year.
• Estradiol options: what is and is not sold in the PH.
• Non-hormonal treatments: if estrogen is not suitable.
