Sulfa rash: Although Benadryl (diphenhydramine) 25-50 mg up to 4 times daily can be taken to control the itching, the rash is unlikely to be controlled by an antihistamine. If the problem is intolerable, you should contact the doctor who prescribed the drug re this issue. The reaction can rarely be life-threatening when the mucous membrane at the eyes, mouth , genitalia become inflamed.

Dry skin?: Dry skin is the likely cause. Avoid scented or anti-bacterial soap or gel, apply a good moisturizer.
