Poison Ivy, Oak, or Sumac
Treatment Overview
The rash (allergic contact dermatitis
) from poison ivy, oak, or sumac generally is mild and can be treated at home. Home treatment for the rash usually helps relieve symptoms but does not speed up healing of the rash.
- If you know you had contact with one of these plants, immediately wash areas of the skin that may have touched the plant. Sometimes the rash can be completely avoided by washing the affected areas with plenty of water within 10 or 15 minutes of contact.
- To relieve itching and help dry blisters, apply wet compresses or soak the area in cool water. Antihistamine pills or calamine lotion may help relieve symptoms.
- If you have a moderate to severe rash, you may need to see your health professional. He or she may prescribe corticosteroid pills. These medicines may help improve or clear up the rash more quickly. Prescription corticosteroid creams, ointments, shots, or gels may also be used, but pills or shots are usually more effective.
A frequent complication of the rash is infection. If this occurs, your health professional will probably prescribe an antibiotic cream that you spread on the affected skin if the infection is small. Otherwise, you may need antibiotic pills or a shot.3To prevent infection, try not to scratch the rash, and cut your fingernails short to minimize the possibility of opening the skin and spreading bacteria.
Regardless of what type of treatment is used after a rash develops, the length of time it lasts will vary from person to person.
