Clobetasol vs Mometasone

When to Apply: Twice a day, on the affected plaques only, in the thinnest film that covers them. One fingertip unit, the amount along the last joint of an adult index finger, covers about two adult palms. Most labels cap use at 50 grams a week. Do not cover it with plastic wrap or a tight dressing unless told to.

How to Start: Twice daily for two weeks, then stop and be reviewed. Some scalp products allow up to four weeks. Keep it off the face, eyelids, armpits and groin unless a clinician prescribed it for that site with a set duration, as in lichen sclerosus.

If It Irritates: Burning and stinging are likelier from alcohol-containing solutions, foams and gels on broken skin; the ointment settles it. Redness or itch that worsens over a week or two can be an allergy to the steroid or a preservative, and needs a different drug.

If It Is Not Working: Two weeks of correct twice-daily use is a proper test. Extending it is the wrong move. Reassess the diagnosis, check for infection, and ask about a different class — clobetasol is already the top of the ladder.

For a standard two-week course on a limited area in a healthy adult, monitoring is a skin check, not a blood test. Did the plaque clear? Has the skin thinned, or have stretch marks or fine blood vessels appeared?

On large areas, under dressings, in repeated courses or in children, the concern is your own cortisol production, and a doctor may test for adrenal suppression. Prescribers also watch how many tubes get dispensed per month.

Clobetasol is not a drug to stay on. Conditions that keep needing it get switched to a weaker steroid, a vitamin D analog, a calcineurin inhibitor or a systemic treatment for maintenance, with clobetasol kept for flares. Around the eyes, prolonged use raises the risk of glaucoma and cataract, another reason eyelid use is not casual.

First few minutesApplying it: A thin layer on the plaque only. Most courses run two weeks.

Days 1 to 3Itch first: Itching and soreness ease quickly, often before the plaque looks different. After months of itch, that is what people notice.

Days 3 to 10Flattening: Scale lifts, thickness drops, redness fades. This is the stage it is prescribed for.

Weeks 1 to 2Judge it here: Clearance is common by two weeks on limbs. Severe eczema flares settle in the same window, as a short rescue, not ongoing treatment.

Weeks 2 to 4Palms and soles: Thick skin absorbs poorly, so results take longer even with a class 1 steroid.

Weeks 4 to 12Lichen sclerosus: The genital skin exception, and one of the few longer courses. Supervised, it reduces itch and helps prevent scarring.

Weeks 6 to 12Scalp alopecia areata and discoid lupus: Slower, less predictable, usually part of a wider plan.

After stoppingHolding: Plaques often return within weeks unless something gentler takes over. Brown or gray patches left behind are pigment change and fade over months.

Generic clobetasol cream, ointment and solution are cheap and usually covered. Branded foams, sprays and shampoos cost many times more than the equivalent tube, and plans often want a generic first.

The weekly limit caps how much you use anyway, so tube size matters less here than with milder steroids. If a branded form is unaffordable, the generic cream or ointment is the same drug at the same strength.
