Intravenous immunoglobulin (IVIG), a medicine given through a vein, also called an IV, is the main treatment. It is effective if given within the first 10 days of the disease. About 20% of children do not respond to the first dose and need to get a second dose. To get this medicine, your child will need to stay in the hospital.
Your child will also need aspirin to help control symptoms like fever, rash and swollen joints. At first, they will likely need high doses. Then, after their temperature is normal, the doctor will lower the dose. Your child will go home and stay on the lower dose for several weeks.
Once treatment starts, children with Kawasaki disease usually start to feel much better within about a day.
If your child has coronary artery problems from Kawasaki disease, they may need other types of care, such as medicines that prevent blood clots, to help prevent further problems.
