Henoch-Schönlein purpura is an immune system reaction. It causes damage to small blood vessels in the skin. This causes a rash in the lower part of the body. It can also affect blood vessels of the joints, intestines, kidneys and other organs. Henoch-Schönlein purpura is also called allergic purpura.
This reaction most often affects children, but can also affect adults. The exact cause is unknown. A recent viral or bacterial infection, certain food or medicines may be a factor. Improvement occurs in 4 to 6 weeks. However, the illness may recur during the next 6 months. This is not a contagious disease and it can't be spread to others.
Have your child rest at home until he or she is feeling better.
Unless told otherwise, feed your child his or her normal diet.
Unless another medicine was prescribed, you can give your child acetaminophen for fever, fussiness or pain. In children over 6 months of age, you may use children's ibuprofen.
Give your child extra fluids for the first few days. For children under 1 year old, continue regular feedings (formula or breast). Between feedings give an oral rehydration solution, which are available from grocery and drug stores without a prescription. For children over 1 year old, give plenty of fluids like water, juice, gelatin, ginger-ale, lemonade, or popsicles.
Follow up with your child's healthcare provider, or as advised.
