Climara patch: once-weekly estradiol, doses and price
Climara is Bayer's once-weekly estradiol patch. It comes in six doses, from 0.025 to 0.1 mg a day, on patches of 6.5 to 25 cm², and goes on the lower abdomen or upper buttock. In its trial, hot flashes fell 67% on 0.05 mg and 72% on 0.1 mg, against 18.1% on placebo. Generics from Mylan and Zydus are approved.

The Climara patch: expectation vs reality
What people often expect
“Climara and Climara Pro are the same patch in different strengths”
What the evidence shows
Climara contains estradiol only. Climara Pro adds a progestin, levonorgestrel, for women with a uterus, and had its first generic approved in October 2026. If you still have a uterus and use Climara, you need a separate progestogen, such as micronized progesterone or a hormonal IUD.
Climara patch: what you need to know
What the Climara patch is
Climara is an estradiol transdermal system you change once a week, on the same day. Bayer HealthCare makes it. The label lists hot flashes and night sweats, vaginal dryness and atrophy, low estrogen after the ovaries are removed or fail, and prevention of bone loss after menopause. It's one of two once-weekly estrogen-only brands; the other, Menostar, is only for bone loss.
Learn more →Climara doses and patch sizes
Climara has six doses: 0.025, 0.0375, 0.05, 0.06, 0.075 and 0.1 mg of estradiol a day, on patches of 6.5, 9.375, 12.5, 15, 18.75 and 25 cm². That makes it much larger than twice-weekly patches: the 0.025 mg Climara is 6.5 cm² against 1.65 cm² for Minivelle. You start at 0.025 mg a day, and your prescriber adjusts from there.
Learn more →How well Climara works for hot flashes
In the Climara trial, 214 women were assigned to 0.05 mg, 0.1 mg or placebo. Weekly hot flashes fell from 46 to 20 on 0.05 mg, a 67% drop, and from 52 to 16 on 0.1 mg, a 72% drop. On placebo they fell 18.1%. That's a big drop for one patch a week. Both doses beat placebo in every treatment cycle of the study.
Learn more →Where to put the Climara patch
Place it on clean, dry skin of your lower abdomen, below the belly button, or the upper outer part of the buttock. Don't put it on or near the breasts. Rotate sites so the same spot isn't used twice in a row. If it lifts, press it back down; if it falls off, the label says to reapply it to a different spot and keep your weekly change day.
Learn more →Climara, swimming and saunas
The label says swimming, bathing and saunas haven't been studied with Climara and may reduce how well it sticks and how much estradiol gets through. The patient leaflet adds that water while swimming, in a sauna, bathing or showering may make the patch fall off. Check the edges after water and press it down; carry a spare if you travel.
Climara generic and price
Drugs.com lists FDA-approved generics of Climara from Mylan Technologies, first approved February 24, 2000, and Zydus, approved March 29, 2023. Cost Plus Drugs listed brand Climara at $53.30 and the generic weekly patch at $36.05 in September 2026, against retail prices of $178.00 and $102.58 elsewhere. If you pay cash, that generic was the cheapest patch we found.
Learn more →Climara and the patch shortage
Weekly patches weren't spared in the 2026 supply squeeze. The FDA said on September 3, 2026 that demand had grown, that it was working with all six manufacturers, and that patches remain available though brands vary by pharmacy. Because Climara's doses differ from twice-weekly brands, ask your prescriber before switching schedules.

Climara or another patch: who each one suits
Climara or its generic if you want one change a week
Strong evidenceIf you're likely to forget, one patch day a week is easier than two, and the generic weekly patch is the cheapest patch at Cost Plus Drugs. It also offers a 0.06 mg step between 0.05 and 0.075 mg. The trade-off is size: 6.5 cm² at the lowest dose.
Related guide →Climara Pro if you have a uterus and want one patch
Strong evidenceClimara Pro puts estradiol and levonorgestrel in one weekly patch, so there's no separate progestogen pill. Its first generic, from Zydus, was approved in October 2026, with no launch date announced.
Related guide →A twice-weekly patch if Climara is too large or won't stay on
Strong evidenceIf you'd like something smaller, Dotti and Minivelle deliver the same range of doses on patches of 1.65 to 7.55 cm². Smaller patches have less edge to catch on clothing. Dotti starts at $58.60 for 8 low-dose patches on Drugs.com.
Related guide →Menostar only if the goal is bone protection
Some evidenceMenostar, also from Bayer and also weekly, releases 14 mcg a day on a 3.25 cm² patch. It's approved only to prevent bone loss after menopause, not for hot flashes.

When to call a doctor on the Climara patch
Urgent: Chest pain, sudden shortness of breath, a painful swollen leg, sudden vision loss or stroke signs
Call 911. These can be signs of a blood clot or stroke, risks listed in the boxed warning of every estrogen patch.
Vaginal bleeding after menopause
See your doctor soon. Unexpected bleeding on estrogen needs checking to rule out a problem with the uterine lining.
A new breast lump
Book an appointment to have it checked.
A rash that spreads, blisters or won't settle when you move the patch
Ask about a smaller twice-weekly patch, gel or pills.

Climara patch: questions women ask
Is there a generic Climara patch?
Yes, and you can ask your pharmacy for one. Drugs.com lists approved generics from Mylan Technologies, first approved in 2000, and Zydus, approved March 29, 2023. They're changed once a week like Climara. Cost Plus Drugs listed the generic weekly patch at $36.05 in September 2026.
Related →Where do you put the Climara patch?
Put it on your lower abdomen below the belly button or the upper outer part of your buttock, on clean, dry skin. Never on or near the breasts. Use a different spot each week and avoid the waistband.
Related →What is the difference between Climara and Climara Pro?
If you take Climara, you're on estradiol only, in one of six doses. Climara Pro is one dose of estradiol, 0.045 mg a day, plus levonorgestrel, 0.015 mg a day, for women who still have a uterus. Both are changed once a week.
Related →What if my Climara patch falls off?
If it lifts, press it down firmly. If it falls off, the label says to reapply it to a different spot and keep your usual weekly change day. Water from swimming, a sauna, a bath or a shower can loosen it, so check the edges afterwards.
What is the lowest dose of Climara?
It's 0.025 mg of estradiol a day, on a 6.5 cm² patch. The label starts treatment for hot flashes and for bone loss at this dose and adjusts it by response, trying to taper or stop at 3 to 6 month intervals.
Related →Is Climara better than Vivelle-Dot?
Neither is better for everyone. Climara is changed once a week and has a 0.06 mg dose; Vivelle-Dot is changed twice a week on a much smaller patch. The right choice depends on which you'll remember and which stays on your skin.
Related →Do I need progesterone with Climara?
If you still have a uterus, yes. Estrogen alone raises the risk of endometrial cancer, so a progestogen such as micronized progesterone or a hormonal IUD is added. After a hysterectomy, estrogen alone is usually enough.
