Vaginal estrogen inserts and rings
Estradiol vaginal inserts and rings deliver a low dose of estrogen directly to the vagina to treat dryness, painful sex and urinary symptoms after menopause. Inserts such as Vagifem, Yuvafem (10 mcg) and Imvexxy (4 or 10 mcg) are used daily for 2 weeks, then twice a week. The Estring ring releases 7.5 mcg a day and is replaced every 90 days. Blood estrogen levels stay low.
Vaginal tablets (10 mcg), softgels and 3-month rings deliver low-dose estrogen locally. How to use each, cost differences, and which suits you.
Vaginal estrogen inserts and rings: expectation vs reality
What people often expect
“Vaginal estrogen tablets and rings are like taking HRT pills and carry the same risks”
What the evidence shows
They're a fraction of the dose. After 12 weeks of Vagifem 10 mcg, average blood estradiol was 5.5 pg/mL. The NHS says vaginal estrogen doesn't increase the risk of breast cancer or blood clots, and in a large US study users had no higher risk of stroke, breast or endometrial cancer. You don't usually need a progestogen with them.
How estradiol vaginal inserts and rings work
Estradiol vaginal inserts (vaginal tablets)
Vagifem and Yuvafem are small 10 mcg estradiol tablets placed in the vagina with a disposable applicator: one a day for 2 weeks, then one twice a week, for example Tuesday and Friday. Each contains estradiol hemihydrate equivalent to 10 mcg of estradiol. They're sometimes called estrogen suppositories. Rarely, the applicator can scratch very thin vaginal tissue.

Imvexxy is a small, soft, tear-shaped insert in 4 mcg and 10 mcg strengths, inserted with a finger, smaller end first, about two inches into the vagina. There's no applicator. The schedule is the same: daily for 2 weeks, then twice a week, every three to four days. The label recommends starting on 4 mcg, the lowest vaginal estradiol dose available.
Estring vaginal estrogen ring
Estring is a soft ring containing 2 mg of estradiol that releases 7.5 mcg a day for 90 days. You or your doctor insert it, and it stays in continuously, then is replaced with a new one. Some women notice it moving, and it can occasionally come out during a bowel movement or straining; if so, rinse it in lukewarm water and put it back in.
Femring: a different kind of estrogen ring
Femring looks similar to Estring but is a systemic estrogen ring. It releases 0.05 or 0.1 mg of estradiol a day for 3 months and is approved for hot flashes, not just vaginal symptoms. Because it raises blood estrogen like a patch, women with a uterus need a progestogen with it, as with other systemic HRT. Check which ring you've been prescribed.
Learn more →How well estrogen inserts and rings work
Low-dose vaginal estrogen improves vaginal dryness and painful sex by about 60% to 80%. A 2024 review of 46 randomized trials in Annals of Internal Medicine found vaginal estrogen may improve dryness, painful sex and treatment satisfaction compared with placebo. Vaginal estrogen also reduced recurrent urinary tract infections (relative risk 0.42). It can take up to 3 months to work fully.
Learn more →Is vaginal estrogen safe?
For most women, yes. In the Women's Health Initiative Observational Study, women with a uterus using vaginal estrogen had no higher risk of stroke, invasive breast cancer, colorectal or endometrial cancer, or blood clots than non-users. The NHS says vaginal estrogen can be used long term. Common side effects are headaches in the first days, vaginal discomfort and spotting in the first months.

Non-hormonal moisturizers and lubricants come first, but low-dose vaginal estrogen may be an option if they don't work, after discussion with your oncologist. In a study of 49,237 women with breast cancer, those who used vaginal estrogen had no higher risk of dying from breast cancer (hazard ratio 0.77) than women who used no HRT. Recurrence risk, how severe symptoms are and personal preference all shape the decision.
Learn more →Vaginal estrogen without a prescription
In the US, all vaginal estrogen needs a prescription. In the UK, the MHRA made Gina 10 mcg estradiol vaginal tablets available from pharmacies without a prescription in 2022, for women aged 50 and over who haven't had a period for at least a year, after a pharmacist's check. In the NHS schedule, one tablet is used daily for 2 weeks, then twice a week.
Learn more →How to insert and remove the Estring ring
Press the ring into an oval and push it into the upper third of the vagina; the exact position isn't critical. When it's in place, you shouldn't feel it, and it shouldn't interfere with sex. If straining moves it lower, push it back up with a finger. To remove it, hook a finger through the ring and pull. If you feel discomfort, it's probably not far enough in.

Vaginal estrogen inserts, ring or cream: which to choose
Vaginal estrogen inserts
Strong evidencePre-measured, clean and quick. Good if you want to avoid the mess of cream and your symptoms are mainly inside the vagina. Twice-weekly dosing after the first 2 weeks. Imvexxy offers the lowest dose and needs no applicator. Blood levels stay very low, averaging 5.5 pg/mL after 12 weeks of Vagifem.
Estring vaginal ring
Strong evidenceBest if you'd rather not think about treatment: one ring every 90 days. It suits women who find twice-weekly dosing easy to forget. Some women feel the ring or find inserting it awkward. It shouldn't interfere with sex, and it can be rinsed and reinserted if it slips out.
Estradiol vaginal cream
Strong evidenceMost flexible, and it can be applied to the vulva as well as inside the vagina, which helps if soreness is on the outside. It can be messier and it's easier to use more than prescribed. The dose is measured with a marked applicator.
Related guide →Prasterone inserts
Some evidenceA nightly DHEA vaginal insert (Intrarosa) and a non-estrogen alternative. The NHS suggests it if vaginal estrogen isn't helping. It must be used every night. It's an option if you prefer to avoid estrogen.
Lubricants and vaginal moisturizers
First stepNo prescription needed. Moisturizers used regularly help mild dryness, and lubricants help during sex. They can be used alongside inserts or a ring. They don't reverse tissue thinning or reduce urinary infections the way estrogen does.

When to see a doctor about vaginal estrogen inserts or a ring
Bleeding after 6 months of vaginal estrogen, or any bleeding after menopause
See a doctor to rule out uterine problems.
More →No improvement after 3 months
Ask about a different product or dose, or prasterone.
Fever, urgent need to pee or pelvic pain
These can be signs of a urinary or vaginal infection.

Talk to your doctor; inserts or cream may suit you better.
Estrogen inserts and rings: questions women ask
How do you use estradiol 10 mcg vaginal inserts?
Insert one into the vagina with the applicator every day for 2 weeks, then twice a week, such as Tuesday and Friday. Keep using them at the maintenance dose, because symptoms usually return if you stop. It can take up to 3 months to feel the full effect.
How do you insert an estradiol tablet without an applicator?
Vagifem and Yuvafem come with applicators, but Imvexxy softgels are designed to be inserted with a finger: hold the larger end, and push the smaller end about two inches into the vagina, lying down or standing. If an applicator irritates very thin tissue, a finger-inserted softgel may be more comfortable.
Is vaginal estrogen safe?
For most women, yes. The NHS says it doesn't increase the risk of breast cancer or blood clots and can be used long term, and a large US study found no higher risk of stroke, breast or endometrial cancer in users. Report any bleeding after the first 6 months.
What are the side effects of an estrogen ring?
Local side effects such as vaginal discomfort, discharge or infection, headaches at first and occasional spotting. Some women feel the ring move or have it slip out during a bowel movement; it can be rinsed and reinserted.
How long does an Estring ring last?
90 days. It releases 7.5 mcg of estradiol a day for 3 months, then you replace it. Leaving it in longer means a falling dose and less effect. You can take it out and reinsert it yourself if needed.
Are estrogen suppositories the same as inserts?
Yes. 'Suppository', 'pessary', 'vaginal tablet' and 'insert' all describe small doses of estrogen placed in the vagina. In the US, estradiol inserts include Vagifem, Yuvafem and Imvexxy. In the UK, Gina and Vagirux are similar 10 mcg tablets.
Do I need progesterone with vaginal estrogen inserts?
Usually not. So little estrogen is absorbed that the NHS says you don't need a progestogen, even if you still have a uterus. The exception is Femring, a systemic ring, which does need one. Tell your doctor about any bleeding.
Which is better: vaginal estrogen inserts, cream or ring?
They work similarly. Choose inserts for convenience, a ring if you want to forget about it for 3 months, or cream if you have soreness on the vulva. Cost and insurance coverage may decide it. All three need a prescription in the US.
