Clobetasol

Clobetasol is a super-high-potency topical corticosteroid available in multiple formulations, each with specific approved uses. Here is the full range:

• Relief of inflammation and itching from corticosteroid-responsive dermatoses — supported by creams, ointments, gels, foam, and topical solution (generally for patients 12 years and older, depending on the formulation)
• Moderate to severe plaque-type psoriasis — Clobetasol Propionate (emollient) cream (ages 16+) and Clobetasol Propionate foam for scalp (ages 12+)
• Moderate to severe plaque psoriasis of the scalp — Clobetasol Propionate shampoo and Clodan shampoo (adults 18 and older)
• Moderate to severe plaque psoriasis affecting up to 20% of body surface — Clobetasol Propionate topical spray (adults 18 and older)
• Mild to moderate plaque psoriasis of non-scalp body regions (excluding the face and skin-fold areas) — Clobetasol Propionate foam (ages 12 and older)
• Inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses — Tovet (emollient formulation) foam (ages 12 and older)
• Moderate to severe plaque psoriasis — Impoyz (Impeklo) cream (adults 18 and older)
• Post-operative inflammation and pain following eye surgery — Byqlovi and Clobetasol Propionate ophthalmic (eye) drops

Clobetasol is a corticosteroid that reduces inflammation by stimulating the production of proteins called lipocortins. These proteins block an enzyme called phospholipase A2, which is responsible for releasing arachidonic acid — the raw material your body uses to manufacture prostaglandins and leukotrienes, two key drivers of inflammation, redness, and itching. By cutting off that supply chain, clobetasol calms the inflammatory response in the skin (or in the eye, when used as eye drops).

Clobetasol is applied directly to the affected area — never swallowed or injected. Most skin formulations are applied twice daily; the shampoo forms are applied once daily to a dry scalp, left for 15 minutes, then lathered and rinsed off. Treatment is typically limited to 2 consecutive weeks for most formulations; some products allow up to 4 weeks for specific conditions under medical supervision. Always use the smallest effective amount for the shortest time necessary, and do not exceed the weekly maximum for your specific product.

• Apply a thin layer and rub in gently — do not use more than directed
• Wash your hands after each application (unless your hands are the treatment area)
• Never apply under a bandage or wrap unless your doctor specifically tells you to
• If you miss an application, apply it as soon as you remember — then continue your regular schedule

Like all strong topical steroids, clobetasol can cause both local (at the skin) and, with prolonged or large-area use, systemic (whole-body) side effects.

• Burning or stinging at the application site
• Itching or dry skin
• Skin thinning (atrophy) or stretch marks (striae)
• Folliculitis (inflamed hair follicles) or acne-like eruptions
• Changes in skin color (hypopigmentation)
• Hair loss (alopecia)
• Headache
• With prolonged use: HPA axis suppression (adrenal suppression), Cushing's syndrome, or high blood sugar from systemic absorption

Some local skin reactions — such as stretch marks or skin thinning — can be permanent. If you notice any signs of systemic effects (unusual fatigue, weight gain, high blood sugar), contact your doctor promptly.

• HPA axis suppression (adrenal suppression): Clobetasol is potent enough to suppress the body's natural cortisol system even at low doses. This risk increases with large treatment areas, prolonged use, use under occlusion, damaged skin, or liver failure. Your doctor may monitor your hormone levels during treatment.
• Cushing's syndrome and high blood sugar: Systemic absorption can cause Cushing's syndrome (a condition from too much cortisol) and may unmask or worsen diabetes. Using more than one steroid-containing product at the same time increases this risk.
• Children at higher risk: Because children have a higher skin-surface-to-body-mass ratio, they absorb proportionally more drug and are at greater risk of adrenal suppression, growth problems, and increased pressure in the skull (intracranial hypertension).
• Local skin reactions: Prolonged use or use under occlusion can cause irreversible skin changes including thinning, stretch marks, and visible dilated blood vessels (telangiectasias).
• Skin infections: If a skin infection develops, appropriate antifungal or antibacterial treatment should be started. If the infection doesn't improve promptly, stop clobetasol until it's under control.
• Allergic contact dermatitis: If the skin condition seems not to be healing rather than getting worse, this may signal an allergic reaction to the product; stop use and consult your doctor.

The FDA labeling for clobetasol does not list specific drug-drug interactions by name, but highlights this important consideration:

• Other corticosteroid-containing products: Using more than one steroid product at the same time — even topical ones — increases the total amount of steroid absorbed into your body and raises the risk of systemic side effects like adrenal suppression

This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.

• Pregnancy: Using large amounts of potent topical corticosteroids during pregnancy has been linked to low birth weight; use on the smallest area of skin for the shortest time possible and discuss with your doctor
• Breastfeeding: It is not known whether clobetasol passes into breast milk; do not apply to the nipple or areola to prevent direct infant exposure
• Children: Age restrictions vary by formulation — some are only for ages 18+, others for 12+; children are at higher risk of systemic side effects and should be monitored carefully
• Liver problems: Liver disease can increase systemic absorption and the risk of side effects; tell your doctor if you have liver failure or significant liver impairment
• Skin atrophy (thinning): Do not use clobetasol on any area where the skin is already thinned
• Rosacea or perioral dermatitis: Clobetasol is not appropriate for these conditions and may make them worse
• Acne: Not recommended for acne vulgaris
• Older adults: Use with caution; dosing should start conservatively given the higher likelihood of other health conditions and medications

If too much clobetasol is absorbed through the skin, it can produce systemic (whole-body) effects, including suppression of the adrenal glands. This is the same risk described in the warnings section. If you think you or someone else has used too much, contact a healthcare provider or poison control for guidance.

Clobetasol is classified in the super-high potency range among topical corticosteroids, as demonstrated in vasoconstrictor studies comparing it to other topical steroids. Studies in adults with plaque psoriasis covering at least 20% of their body found that roughly 15–20% of patients showed signs of adrenal (HPA axis) suppression after 2–4 weeks of twice-daily use. Importantly, this suppression was reversible — all affected patients' hormone levels returned to normal after stopping the medication.

Clobetasol can be absorbed through intact skin, and that absorption increases significantly when the skin is inflamed, damaged, or covered with an occlusive dressing. Once in the bloodstream, it is processed primarily in the liver and excreted by the kidneys; some metabolites are also eliminated through bile. A pharmacokinetic study of Impoyz (Impeklo) cream in adults with moderate to severe psoriasis found low but measurable blood levels of clobetasol after 15 days of twice-daily use, confirming that systemic absorption does occur with topical application.

Store at 20° to 25°C (68° to 77°F); excursions permitted between 15° to 30°C (59° to 86°F) . store at temperatures above 120°F (49°C). Keep out of reach of children.
