What are the treatment options for drug rash?

A drug rash is a skin reaction that may appear after starting, stopping, or changing a medicine, although the timing and pattern vary. The same appearance can also come from an infection or another skin condition. A clinician reviews every medicine, supplement, dose change, and the date symptoms began. Do not assume a medicine is the cause or restart a suspected medicine without advice.

Contact the prescriber promptly so the suspected medicine can be weighed against the reason it was prescribed. Some medicines should not be stopped suddenly, while others may need substitution; make that decision with a clinician. Oral Antihistamine Therapy may ease itch for selected patients. Topical Corticosteroids may calm inflammation when prescribed for the affected area and duration. Keep a list of medicines and take photographs if the rash changes before review.

Get emergency help for trouble breathing, facial or tongue swelling, faintness, widespread blistering, skin peeling, severe skin pain, mouth or eye sores, or a rapidly spreading rash with fever. These features can signal a serious reaction and should not be managed with home creams alone. A milder new rash still deserves prompt medication review.

Ask which medicine is most suspicious, whether it can be paused or replaced safely, which symptoms need emergency attention, and how long to use any antihistamine or topical steroid. Ask what should be recorded for future prescriptions.
