What should I do if I miss a dose?

Give your child the dose as soon as you remember and then continue to take it as you normally give. However, if it is almost time for the next dose, skip the dose you missed and give the next dose at the usual time.

Do not double or increase the dose.

If your child has missed more than two doses or you are not sure of what to do, consult your doctor or pharmacist.
