Question: can you take allergy medicine for a rash?
Answer: If you think a medication caused your rash, stop using it and contact your primary care provider. Use an over-the-counter anti-itch drug. A nonprescription oral antihistamine, such as loratadine (Claritin), cetirizine (Zyrtec Allergy) or diphenhydramine (Benadryl Allergy, others), may help relieve itching.
