Allergic Itching Treatment & Prevention
An allergic or irritant itch is often associated with inflammation of the skin — commonly known as a rash — or contact dermatitis. Allergic itch and rash can be caused by skin sensitivities to an insect sting or bite, poison ivy/oak/sumac, certain ingredients in personal care products (e.g., fragrance or harsh detergents), or certain metals in jewelry (e.g., nickel).
Signs of allergic or irritant rash:
- Swelling or bumps
- Oozing or blistering
- Flakiness or scaliness of skin
Most rashes are not serious and will go away on their own. Treat the symptoms and wait a few days to see if the rash subsides. If the rash is severe, is accompanied by other symptoms or appears to be quickly getting worse, see a doctor.
Redness caused by inflammation can be treated with a cream containing a hydrocortisone, such as POLYSPORIN® 1% Hydrocortisone Anti-Itch Cream, which can be purchased in a drugstore. Itchy skin can be treated by applying a medicated anti-itch cream, such as POLYSPORIN® Itch Relief Lotion, or 1 % Hydrocortisone Anti-Itch Cream, or by taking an antihistamine by mouth (e.g., diphenhydramine, cetirizine).
Cleanse the rash with a mild soap and water and apply a light fragrance-free moisturizer. If the rash is oozing, then you should keep it covered lightly with a non-stick dressing to soak up the fluid.
If the rash does not subside within a week or appears to be getting worse, go see your doctor so that you can get the appropriate diagnosis and treatment.
- Moisturize your skin regularly to avoid dry skin and strengthen the skin barrier to help prevent future inflammation or redness.
- Keep your baths and showers short, and bathe in lukewarm water to avoid losing your skin's natural oils.
- Choose fragrance-free soaps and laundry detergents.
- Avoid itching. Try an anti-itch medicated cream, like POLYSPORIN® Itch Relief Lotion, or POLYSPORIN® 1% Hydrocortisone Anti-Itch Cream, if needed.
- Keep your skin cool, especially when you are sleeping.
- Create a food diary if your suspect your skin rash or irritation is an allergic reaction to something you have consumed. If you make a connection between a food item and the condition of your skin, eliminate that item from your diet.
