- USES
-
- This medication belongs to a group of drugs known as antihistamines

- To avoid stomach upset, you can take cyproheptadine with food or with a
- full glass of milk or water (unless your doctor directs you to do otherwise).
- The oral syrup should be measured carefully with a specially designed
- 5-ml measuring spoon. An ordinary kitchen teaspoon is not accurate enough.
- If you miss a dose of this medication, take the missed dose as soon as
- possible, unless it is almost time for your next dose. If it is almost time
- for the next dose, do not take the missed dose at all; just return to your
- regular dosing schedule. Do not double the next dose.

- should disappear as your body adjusts to the medication.
