Calamine lotion. Applying this over-the-counter (OTC) anti-itch medication can help soothe your symptoms.
OTC hydrocortisone topical cream. This product can help ease the itch.
Prescription corticosteroid medicine. If your reaction is severe or affects sensitive parts of your body — such as the mouth, on or near the eyes, or genitals — see your doctor for a prescription, such as prednisone. Depending on where your rash is, your doctor may recommend the steroid be taken by mouth or be applied directly to the skin. You may also need an injection of corticosteroid. This treatment is meant to help reduce the severity of your reaction, though it can have side effects.
Antihistamines in pill form. These can also be used to reduce itching.
Aluminum hydroxide gel, zinc acetate, or zinc oxide. Doctors may recommend these treatments to dry out wet blisters, which often ooze liquid.
Antibiotic ointment or medication. Some people develop a skin infection with inflammation — such as cellulitis or folliculitis — around their rash, especially if they’ve been itching it. In this case, your doctor will prescribe antibiotics. It’s likely your rash is infected if you have:
- a fever
- feel swelling around the rash
- feel warmth around the rash
- see pus around the rash
Don’t apply antihistamine to your skin, as that can cause further irritation. You should also avoid topical anesthetics, such as benzocaine.
