Over-the-counter medications for treating a rash include 1 percent hydrocortisone cream, moisturizing lotions, oral antihistamines and topical antifungal medications, notes MedicineNet. Many rashes get better on their own, but if they persist after a few days, it is advisable to seek medical treatment.
Properly treating a rash depends on its type and cause; however, the most common types of rashes are viral, bacterial and fungal, states MedicineNet. Eczema may be treated with warm-water compresses, followed by moisture evaporation and emollient moisturizers or lotions.
With any type of rash, it is important to avoid contact with substances that may irritate or make it worse, according to WebMD. Avoid contact with soaps, perfumes and scratchy fabrics, such as wool. Additionally, stay away from potential allergens, such as animal dander, dust mites and certain foods.
Other measures include resisting the urge to scratch as much as possible, explains WebMD. Cutting the fingernails may help to alleviate additional irritation to the skin if scratching does occur. Coal tar may help reduce itching when applied to the affected area. Exposure to sunlight is known to help cases of dermatitis; however, it is important not to develop sunburn or to sweat too much, which aggravates the skin more. Stress is often an underlying cause for skin to break out, and relaxation techniques may be very beneficial to relieve and prevent future occurrences of rash.
