What Is Menest? Uses, Dosage, and What You Need to Know in 2026

Menest is a brand-name oral estrogen medication manufactured by Pfizer. Its generic name is esterified estrogens — a mixture of estrogen compounds derived from both equine (horse) and plant sources. Menest has been used for decades to help women manage the hormonal changes of menopause and related conditions.

What Is Menest Used For?

Menest is FDA-approved for the following indications:

Moderate to severe menopausal vasomotor symptoms — hot flashes, night sweats, and flushing caused by declining estrogen levels during menopause

Moderate to severe vulvar and vaginal atrophy — vaginal dryness, burning, irritation, and painful intercourse associated with menopause

Female hypogonadism — conditions where the ovaries produce insufficient estrogen, often in younger women

Female castration and primary ovarian failure — estrogen replacement after surgical removal of the ovaries or premature ovarian insufficiency

Advanced breast cancer (palliative, in men and women) — to help relieve symptoms; does not treat the underlying cancer

Advanced prostate cancer (palliative) — to help manage symptoms in men with advanced disease; does not cure the cancer

Note: Menest is not FDA-approved for osteoporosis prevention. If osteoporosis prevention is a goal, discuss alternatives like estradiol with your doctor.

What Are the Available Doses?

Menest comes as film-coated oral tablets in three strengths:

0.3 mg — the lowest available strength; used to find the minimal effective dose

0.625 mg — the most commonly prescribed strength for menopausal symptoms

1.25 mg — used for more severe symptoms or specific indications like ovarian failure

The 2.5 mg strength was permanently discontinued by Pfizer. Always start at the lowest dose that controls your symptoms, as recommended by the FDA and your prescriber.

How Do You Take Menest?

Menest is taken by mouth, with or without food. Taking it with food or immediately after eating can help reduce nausea. For menopause symptoms, it is typically taken cyclically: 3 weeks on, then 1 week off. Some patients are maintained on a continuous daily schedule — follow your prescriber's specific instructions.

Typical dosing by indication:

Menopause symptoms: 0.3–1.25 mg daily, cyclically; start at lowest effective dose

Female hypogonadism: 2.5–7.5 mg daily in divided doses for 20 days, followed by 10 days rest

Ovarian failure/female castration: 1.25 mg daily, cyclically; adjust based on response

Who Should Not Take Menest?

Menest is contraindicated (not safe to use) in people who:

Are pregnant or may be pregnant

Have undiagnosed abnormal vaginal bleeding

Have a known or suspected history of breast or uterine cancer (unless being treated for it)

Have a history of blood clots (DVT, pulmonary embolism, stroke) caused by estrogen or hormones

Have active liver disease

Is There a Generic Version?

Yes. Generic esterified estrogen tablets are the same medication as Menest and are available in the same strengths (0.3 mg, 0.625 mg, 1.25 mg). The generic is often less expensive and may be easier to find at pharmacies. Ask your doctor or pharmacist about substituting the generic if Menest is hard to find or too costly.

How Long Is Menest Taken?

The FDA recommends using Menest at the lowest effective dose for the shortest duration that meets your treatment needs. You and your prescriber should reassess the need for therapy every 3–6 months. Many patients take Menest for 2–5 years for menopause symptom control; some may take it longer based on their individual circumstances and risk profile.
