Aldara Side Effects

Treatment area reactions may include redness, swelling, itching, burning, pain/tenderness, thickening/hardening of the skin, peeling/flaking/scabbing/crusting, or leaking a clear fluid. Also, changes in skin color may occur and may not go away. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

If the skin reaction is severe (bleeding, formation of sores/blisters/ulcers), imiquimod may need to be temporarily stopped so that the skin can heal. Follow your doctor's directions.

Flu-like symptoms (such as fever, tiredness, muscle aches), runny/stuffy nose, cough, diarrhea, nausea, and back pain may also occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
