Treatment

How is Kawasaki disease treated?

Your doctor will prescribe medicines to make your child feel better and to prevent the problems Kawasaki disease can cause.

Your doctor might also give your child a medicine called immunoglobulin to help prevent heart problems. Immunoglobulin is given intravenously (through your child\'s veins) for several hours. It has to be given in the hospital.

Your doctor may give your child high doses of aspirin to lower the fever. Aspirin also helps with the rash and the joint pain. It can keep your child\'s blood making clots. After the fever goes down, your doctor might give your child a lower dose of aspirin for several weeks to reduce the chance of heart problems. (However, if your child gets the flu or chickenpox during this time, you\'ll have to stop giving your child aspirin for a while. When children take aspirin during the flu or chickenpox, they might get another illness called Reye\'s syndrome. For this reason, don\'t give your child aspirin unless your doctor tells you to.)

Complications

How serious is Kawasaki disease?

It can make you a little scared to find out your child has Kawasaki disease. Your child won\'t feel well, and the rash and other signs of Kawasaki disease may look scary. Just remember that most children who have Kawasaki disease get well with no problems.

However, Kawasaki disease can cause heart problems in 1 out of every 50 children affected by the disease. If your child gets heart problems Kawasaki disease, your doctor will talk with you about any special care your child needs.

Kawasaki disease can also cause problems like swelling in your child\'s joints, but these problems usually go away without special treatment. It helps if your doctor finds out about the Kawasaki disease at an early stage and starts treatment soon. Early treatment means your child probably won\'t get lasting heart problems or joint problems.
