How do dermatologists treat poison ivy?
If you have a serious reaction, you will likely need prescription medicine. Your dermatologist may prescribe a steroid ointment that you can apply to the skin. To treat a severe case, a strong medicine like prednisone may be necessary.
If you have an infection, your dermatologist may prescribe an antibiotic. You likely have an infection if you develop a fever or have pus, pain, swelling, and warmth around the rash.
If you are not sure what caused your rash, you should see a dermatologist. Rashes appear on the skin for many reasons.
