Anaphylactoid Purpura

Admission Information and Discharge Instructions

What is anaphylactoid purpura?

Anaphylactoid purpura is an inflammation of blood vessels. This inflammation can happen in any organ or blood vessel, but the rash caused by leaking blood vessels is easiest to see and feel on the skin. The official disease name is Henoch-Schoenlein purpura (HSP).

What is the cause?

The cause of this illness is not known, but there is a trigger in the body that causes inflammation (swelling) in the blood vessels. Triggers may include a recent cold, allergic reaction to medicines, insect bites, cold, chemicals, or certain foods.

It affects children age 3 to 17 years old. HSP is not an inherited disease. It is not contagious and cannot be prevented.

How can I take care of my child at home?

  • Anti-inflammatory medications

    The best and safest medicine to give to help with the pain and inflammation is ibuprofen (Advil or Motrin). Use the same dose you use to treat your child's fever. Do not use aspirin. Check with your healthcare provider before you give any medicine that contains aspirin or salicylates to a child or teen. This includes medicines like baby aspirin, some cold medicines, and Pepto Bismol. Children and teens who take aspirin are at risk for a serious illness called Reye's syndrome.

    Acetaminophen (Tylenol) may help with the pain, but it will not relieve swelling and inflammation. Your child's dose of ibuprofen is ____ mg every 6 to 8 hours as needed for pain or swelling.

  • Steroid medications
