Clascoterone

Androgen receptor inhibitor1 FDA label read

Clascoterone is sold as Winlevi and stands alone in this category by mechanism: it is a topical androgen receptor inhibitor, approved for acne in patients 12 years of age and older. Every other acne medication on these pages works through retinoid receptors, bacteria or keratin - this one addresses androgen signaling in the skin.

Brands and what each one is approved for

One active ingredient can hold several separate FDA approvals. They are different documents with different approved uses, and mixing them up is the most common mistake made about these medications.

The opening of the pregnancy section of the label. The full section is longer and is in the source document.

In animal reproduction studies, subcutaneous administration of clascoterone to pregnant rats and rabbits during organogenesis at doses 8 or 39 times the maximum recommended human dose (MRHD), respectively, increased malformations in rats and post-implantation loss and resorptions in rabbits...

What affects the cost

Winlevi is brand-only, and the acquisition cost below is a brand price. What a person pays depends on insurance coverage. This site sells nothing and links to no sellers.

What pharmacies pay for it

These are acquisition costs: what pharmacies in the United States pay on average to buy the medication, published weekly by the Centers for Medicare and Medicaid Services. They are not retail prices and not what a person pays at the counter, which depends on insurance, pharmacy and discount programs. They are useful as an objective floor and for seeing how far a brand sits above its generic.

Compared with other medications

What the labels do not do is compare one medication against another. These pages put two of them side by side.

Common questions

Is Winlevi a hormone treatment?
Its label calls it an androgen receptor inhibitor applied to the skin, and separately warns that suppression of the hypothalamic-pituitary-adrenal axis may occur during or after treatment, with an instruction to attempt withdrawal if it develops. What that means for a particular person is a question for a clinician.
How does Winlevi differ from spironolactone for acne?
Winlevi is approved for acne; spironolactone is not. The spironolactone label covers heart failure, hypertension, edema and primary hyperaldosteronism, and acne appears nowhere in it. The comparison page sets the two documents side by side.
From what age is Winlevi approved?
The label covers patients 12 years of age and older.
