Allergy: Poison Ivy, Oak, and Sumac (cont.)
IN THIS ARTICLE
The rash and itching usually get better gradually and go away completely in two to three weeks. Treatment should be continued at least this long because the rash can come back if medicines are stopped too soon. You may have temporary darkening of your skin when the rash disappears.
Surrounding redness, pain, and pus can indicate a skin infection, which your doctor can treat with antibiotics. This is more likely to happen if the rash is scratched so much that the skin is broken.
You almost certainly will have another reaction if you come in contact with these plants again after a first reaction.
