1. Wash your skin with soap and water as soon as possible after coming into contact with poison ivy. This will help to remove any of the oil that may be on your skin.
2. Apply a cold compress to the affected area. This will help to reduce swelling and itching.
3. Take an oral antihistamine, such as Benadryl or Claritin, to help relieve itching.
4. Apply a topical corticosteroid cream or ointment to the affected area. This will help to reduce inflammation and itching.
5. Avoid scratching the affected area. Scratching can make the rash worse and can lead to infection.
If your poison ivy rash is severe, or if it does not improve after a few days, you may need to see a doctor. The doctor may prescribe a stronger medication to help relieve your symptoms.
