Examples of at-home treatments for contact skin rashes include using gentle cleansing agents, using warm water instead of hot and letting the rash breathe by not covering it with clothing or bandages. Another method is to stop using any new lotions or cosmetics, as these may have triggered the rash, reports Healthline.
Scratching itchy rashes should be avoided. Over-the-counter topical anti-itch creams help treat itchy skin rashes. Lotions that contain calamine help soothe rashes caused by chicken pox and poison ivy or oak, according to Healthline. Oatmeal baths are another soothing treatment for skin rashes, especially rashes caused by eczema, shingles or psoriasis. If the rash is accompanied by pain, taking acetaminophen or ibuprofen may help.
Most contact rashes heal without medical treatment, but if the rash is accompanied by increasing pain, discoloration, difficulty breathing or swelling in the face, it may require immediate medical attention, warns Healthline. Additional symptoms that indicate a serious issue include a fever, confusion, dizziness, severe head or neck pain, and vomiting or diarrhea.
Common causes of contact rashes include cosmetics, soaps, laundry detergents, clothing dyes, chemicals found in latex or rubber, and poisonous plants. Rashes are also sometimes caused by side effects of or allergic reactions to certain drugs, Healthline explains.
