Your dermatologist may recommend a prescription for topical cortisone cream that can be applied directly to the rash to help decrease the symptoms and inflammation caused by the resin. Although there are over-the-counter ointments for treating the rash, prescription-strength cortisone creams that your dermatologist can recommend will usually provide much faster relief from the itching and aid healing. In severe cases, a course of oral prednisone may be prescribed.
A superficial infection can sometimes develop at the site of the rash caused by poison ivy, oak or sumac. In these cases, a topical or oral antibiotic may be necessary. If you have swelling, pain, warmth, pus, or other concerning signs at the site of your rash you should have your dermatologist evaluate your condition.
The eruption usually resolves within one to three weeks.
