Climara is a once-weekly prescription Estradiol transdermal patch used to treat menopause symptoms like hot flashes and vaginal dryness, and to prevent postmenopausal osteoporosis.

What Is Climara?

Climara is the brand name for an Estradiol transdermal system manufactured by Bayer HealthCare Pharmaceuticals. It was first approved by the FDA on December 22, 1994, making it one of the longest-established hormone replacement therapy patches on the market.

The active ingredient is Estradiol (sometimes written as 17β-estradiol), which is the most potent naturally occurring form of estrogen. Climara belongs to the Estrogens drug class. It is not a controlled substance but requires a prescription.

What makes Climara different from many other Estradiol patches is its once-weekly dosing schedule. While popular alternatives like Vivelle-Dot, Dotti, and Minivelle need to be changed twice a week, Climara delivers a steady dose of Estradiol for a full seven days from a single patch.

Generic versions of Climara are available from Mylan Technologies (approved 2000) and Zydus Pharmaceuticals (approved 2023). These generics are also once-weekly Estradiol patches and are FDA-rated as therapeutically equivalent to Climara.

What Is Climara Used For?

Climara is FDA-approved for:

• Treatment of moderate to severe vasomotor symptoms (hot flashes) associated with menopause — including hot flashes, night sweats, and flushing.
• Treatment of moderate to severe vulvar and vaginal atrophy associated with menopause — including vaginal dryness, burning, and irritation.
• Prevention of postmenopausal osteoporosis — Estradiol helps maintain bone density. However, if you're using it solely for osteoporosis prevention, your doctor should consider whether non-estrogen treatments might be more appropriate.
• Treatment of hypoestrogenism due to hypogonadism, castration (surgical removal of ovaries), or primary ovarian failure.

Climara is not approved for preventing heart disease, stroke, or dementia. In fact, its boxed warning states that it should not be used for these purposes, as it may increase those risks. For more on safety concerns, see our article on Climara side effects.

How Is Climara Taken?

Application

Climara is a thin, flat patch that sticks to your skin and releases Estradiol continuously for seven days. Here's how to use it:

1. Choose an application site: Apply to clean, dry skin on your lower stomach (abdomen) or buttocks. Do not apply to your breasts.
2. Prepare the skin: Make sure the area is clean, dry, and free of lotions, oils, or powders. Don't apply to skin that is irritated, damaged, or broken.
3. Apply the patch: Remove the patch from its protective pouch and peel off the backing. Press the sticky side firmly onto your skin for about 10 seconds.
4. Rotate sites: Use a different spot each week. Wait at least one week before reusing the same location.
5. Change weekly: Remove the old patch and apply a new one on the same day each week. Fold the used patch in half (sticky sides together) and dispose of it safely out of reach of children and pets.

Available Strengths

Climara comes in six different strengths based on how much Estradiol the patch delivers per day:

• 0.025 mg/day (lowest dose)
• 0.0375 mg/day
• 0.05 mg/day
• 0.06 mg/day
• 0.075 mg/day
• 0.1 mg/day (highest dose)

Your doctor will typically start with the lowest effective dose and adjust based on your symptoms and response. Each box contains 4 patches (a one-month supply).

What If the Patch Falls Off?

If your Climara patch falls off, try pressing it back into place. If it won't stick, apply a new patch to a different area and continue with your regular schedule. Don't apply two patches at the same time unless directed by your doctor.

Who Should Not Take Climara?

Climara is not safe for everyone. You should not use Climara if you have:

• Undiagnosed abnormal vaginal bleeding
• Known or suspected breast cancer or other estrogen-dependent cancer
• Active blood clots (deep vein thrombosis or pulmonary embolism) or a history of blood clots
• Active or recent stroke or heart attack
• Liver disease or liver dysfunction
• A known allergy to Estradiol or any component of the patch
• A current pregnancy (FDA Pregnancy Category X)

Tell your doctor about your full medical history before starting Climara, especially if you have heart disease risk factors, a history of migraines, epilepsy, asthma, kidney disease, gallbladder disease, or endometriosis. See our article on Climara drug interactions for medications and supplements that may affect how Climara works.

How Much Does Climara Cost?

Climara's cost depends on whether you use the brand-name version or a generic, and whether you have insurance:

• Brand-name Climara (without insurance): $120–$180 per month for 4 patches
• Generic Estradiol patch (without insurance): $55–$80 per month for 4 patches with a discount card from GoodRx, SingleCare, or Optum Perks
• With insurance: $10–$50 per month (varies by plan; generic is usually Tier 2)

Availability in 2026

Climara and other Estradiol patches are currently affected by a nationwide supply shortage. Once-weekly patches like Climara have generally had more stable availability than twice-weekly patches, but supply still varies by pharmacy and location.
