Femring Is a Prescription Estrogen Vaginal Ring for Menopause

Femring is a flexible vaginal ring that delivers Estradiol Acetate, a form of estrogen, directly into your body over 3 months. It's FDA-approved to treat moderate-to-severe hot flashes and vaginal atrophy caused by menopause.

What sets Femring apart from other vaginal estrogen products is that it delivers systemic levels of estrogen — meaning it doesn't just work locally in the vagina. It raises estrogen levels throughout your body, treating both vaginal symptoms and vasomotor symptoms (hot flashes and night sweats).

This guide covers everything you need to know about Femring in 2026: what it's used for, how to take it, who should avoid it, and what it costs.

What Is Femring?

Femring is a brand-name prescription medication made by Millicent Pharma. It belongs to a class of drugs called estrogens and is used as hormone replacement therapy (HRT) for postmenopausal women.

The active ingredient is Estradiol Acetate, which your body converts into estradiol — the primary form of estrogen your ovaries produced before menopause. By restoring estrogen levels, Femring relieves the symptoms that come with declining hormones.

Unlike Estring (a different vaginal ring that provides only low-dose local estrogen), Femring delivers enough estrogen to reach the bloodstream and treat whole-body symptoms. For a detailed comparison, see our article on alternatives to Femring.

What Is Femring Used For?

Femring is FDA-approved for two conditions:

1. Moderate-to-severe vasomotor symptoms (hot flashes): These include hot flashes, night sweats, flushing, and related sleep disruption caused by menopause.
2. Moderate-to-severe vulvar and vaginal atrophy: This includes vaginal dryness, itching, burning, and painful intercourse associated with menopause.

Because Femring provides systemic estrogen, it's particularly useful for women who need relief from both vaginal and whole-body menopausal symptoms — all from a single product that you replace every 3 months.

Some providers may also consider it for genitourinary syndrome of menopause (GSM), a broader term that covers vaginal, urinary, and sexual symptoms related to estrogen decline.

How Is Femring Taken?

Femring is designed to be simple and low-maintenance:

1. Insert the ring: You insert Femring into your vagina yourself, pushing it in as far as it comfortably goes. The exact position doesn't matter — if you can't feel it, it's in the right place.
2. Leave it in for 3 months: The ring stays in place continuously, delivering a steady dose of Estradiol Acetate every day.
3. Replace it: After 3 months, remove the old ring by hooking your finger through it and pulling gently. Then insert a new one.

Important notes:

• If the ring slips out, rinse it in lukewarm water (not hot) and reinsert it.
• You don't need to remove it during intercourse, bathing, or exercise — but you can if you prefer.
• If you remove it for any reason, rinse and reinsert it as soon as possible.

Dosage Options

Femring comes in two strengths:

• 0.05 mg/day (the ring contains 12.4 mg of Estradiol Acetate total)
• 0.10 mg/day (the ring contains 24.8 mg of Estradiol Acetate total)

Your doctor will typically start with the 0.05 mg/day ring and increase only if needed. The goal is always to use the lowest effective dose for the shortest time necessary.

Who Should Not Take Femring?

Femring is not right for everyone. It carries a boxed warning (the FDA's most serious safety alert) and is contraindicated in the following situations:

• Undiagnosed abnormal vaginal bleeding
• Known or suspected breast cancer, or a history of breast cancer
• Known or suspected estrogen-dependent tumors
• Active blood clots (DVT or pulmonary embolism), or a history of blood clots
• Active or recent stroke or heart attack
• Known liver disease or impairment
• Known blood clotting disorders (protein C, protein S, or antithrombin deficiency)
• Known allergy to Femring or its components
• Pregnancy

The boxed warning specifically highlights increased risks of:

• Endometrial cancer (when estrogen is used without a progestin in women with a uterus)
• Stroke and blood clots
• Breast cancer (with long-term estrogen plus progestin use)
• Probable dementia in women 65 and older

If you still have your uterus, your doctor will prescribe a progestin alongside Femring to reduce endometrial cancer risk.

How Much Does Femring Cost?

Femring is a brand-name medication with no generic available as of 2026. That makes it expensive:

• Without insurance: $895 to $1,100 per ring (a 3-month supply)
• With insurance: Coverage varies widely. Many plans cover Femring but may require prior authorization or step therapy (trying a cheaper option first). Medicare Part D may cover it with varying copays.

There are ways to reduce the cost:

• Prescription discount cards: GoodRx, SingleCare, and others may offer savings.
• Manufacturer savings: Millicent Pharma has previously offered a Femring savings program. Check femring.com for current availability.
• Patient assistance programs: Resources like RxAssist and NeedyMeds can help connect you with financial help.

Final Thoughts

Femring is a unique option in the menopause treatment landscape. It combines the convenience of a 3-month vaginal ring with systemic estrogen delivery, making it a good fit for women who need relief from both hot flashes and vaginal symptoms.

Like all hormone therapy, it comes with real risks and isn't right for everyone. The best approach is an honest conversation with your doctor about your symptoms, medical history, and goals.
