What Do Topical Corticosteroids Treat?

These medicines lower inflammation in the skin, easing redness, swelling, and itch. A clinician may prescribe them for [Hand Eczema](/conditions/hand-eczema/), [Irritant Contact Dermatitis](/conditions/irritant-contact-dermatitis/), [Heat Rash](/conditions/heat-rash/), or reactions to [Insect Bites](/conditions/insect-bites/). They may also be part of care for lichen planus, granuloma annulare, guttate psoriasis, or a fixed drug eruption. The right strength depends on the diagnosis and location; thin facial skin and skin folds generally need particular caution.

Use a thin layer on the affected skin at the advised frequency, then wash your hands unless your hands are the treatment area. Keep the medicine away from eyes and broken skin unless instructed. Do not use a stronger product, extend the course, or cover the area with a dressing without professional guidance. Moisturiser, gentle cleansing, and avoiding the trigger can support recovery when contact irritation is involved.

Seek medical advice if the rash becomes painful, warm, crusted, blistered, or rapidly expands, or if it does not respond as expected. Get urgent help for facial swelling, breathing difficulty, or a severe widespread reaction. Stop self-treatment and arrange assessment for a new rash after a medicine, an infected-looking area, or symptoms near the eye.

Ask which strength and body-site instructions apply, how long the course should last, and whether you should taper or stop directly. Ask what symptoms suggest infection or a medicine reaction, including [Fixed Drug Eruption](/conditions/fixed-drug-eruption/).
