Making sure your child avoids the poisonous plants is the best treatment. It is important to teach your children what the plants look like and not to touch them. Bathe your pet if it comes in contact with the plants.
If contact with the plants has already occurred, remove the oils from the skin as soon as possible. Cleaning the skin with an ordinary soap within six hours after the initial exposure has proven to be effective. Wash all clothes and shoes.
If the rash is on the face, near the genitals, or all over the body, call your child’s doctor. After a medical history and physical exam, your child's doctor may prescribe a steroid cream or steroids to help with the swelling and itching.
Bathing in an oatmeal bath product may reduce itching. The doctor may also prescribe medication by mouth for itching.
