How is INTUNIV given?

Your child should not stop taking INTUNIV or change the dose until you talk with the doctor. Talk with the doctor about what to do if your child does not take INTUNIV as prescribed. INTUNIV doses are gradually increased when your child starts to take it, and will need to be gradually decreased if you or your child's doctor decides to have your child stop taking INTUNIV. Talk to your child's doctor before making any changes to how your child takes INTUNIV.
