Itching is annoying and can ruin your day — and your sleep. Most of the time it’s harmless: dry skin, mosquito bites, or a reaction to soap. But sometimes itch points to an allergy, infection, or a medication side effect. This page gives clear, practical steps you can try right now and tells you when to see a doctor.
Dry skin is the simplest culprit. If your skin feels tight or flaky, use a fragrance-free moisturizer after showering and switch to a mild soap. Hot showers and strong detergents make dryness worse, so cool down the water and use gentle laundry products.
Allergic reactions — to foods, plants, or cosmetics — often cause sudden, itchy patches. Stop new products and rinse the area with cool water. An oral antihistamine (like cetirizine or loratadine) can help at night when itch keeps you awake. For short-term relief on localized spots, a 1% hydrocortisone cream applied once or twice daily usually works.
Infections such as fungal rashes (athlete’s foot, jock itch) need antifungal creams. If the itchy area is red, scaly, or in body folds, try an antifungal product and keep the area dry. Scabies and some insect bites need prescription treatment, so see your provider if OTC products don’t help.
Medications can cause itching too. If you started a new drug and itching began soon after, call your prescriber — don’t stop important medicines without advice. Pregnancy can cause intense itch in some women; if you’re pregnant and very itchy, mention it to your care team promptly.
Get medical help if itching is severe, covers large areas, won’t stop after a week, or comes with fever, weight loss, jaundice (yellow skin), swelling, or breathing trouble. These signs suggest a more serious problem that needs tests. If the skin looks infected (spreading redness, pus, warmth), you may need antibiotics.
Your clinician will ask when it started, what makes it better or worse, and about new products or medicines. They may examine your skin, do simple blood tests, or take a skin scraping to check for fungus or scabies. Treatment can include prescription creams, a short steroid course, or switching medicines.
To avoid making itch worse: keep nails short, use cool compresses, wear soft fabrics, and try not to scratch — scratching damages skin and invites infection. For long-term or unexplained itch, ask for a referral to dermatology.
