What should you know about itchy skin treatment?

Itching may come from dry skin, atopic dermatitis, contact dermatitis, hives, psoriasis, scabies, a yeast infection, or another skin or general health issue. A moisturiser may help a dry barrier, but it will not treat every cause. A clinician may inspect the rash, ask about new products and medicines, and choose a topical treatment, an anti-itch medicine, an antimicrobial treatment, or another approach when appropriate. The same product is not suitable for every body site, age, pregnancy status, or skin type.

Apply a plain fragrance-free moisturiser after washing, use lukewarm rather than hot water, and pat the skin dry. Wear breathable clothing and use a cool compress for short periods. Stop newly introduced fragranced products and avoid scrubbing or scratching. Ask a pharmacist or clinician before using medicated creams on the face, skin folds, genitals, broken skin, or in children. If a product stings, causes swelling, or worsens the rash, stop it and seek advice.

Arrange an appointment when itching lasts, keeps returning, covers much of the body, disrupts sleep, or has no visible rash. Seek prompt care for spreading redness, warmth, pus, fever, painful cracks, blistering, or skin peeling. Emergency help is needed for breathing difficulty, swelling of the lips or tongue, faintness, or a rapidly developing widespread allergic rash. Take photographs and list products or medicines that preceded the flare.
