Complications
If you scratch a poison ivy rash, bacteria under your fingernails may cause the skin to become infected. See your doctor if pus starts oozing from the blisters. Your doctor might prescribe antibiotics. Serious difficulty breathing and inflammation of the lining of the lungs may result from inhaling urushiol.
