Tab is a membership, not insurance. Covered medications require a prescription from a licensed clinician.
Cyproheptadine dosage and administration
DOSAGE SHOULD BE INDIVIDUALIZED ACCORDING TO THE NEEDS AND THE RESPONSE OF THE PATIENT. Children: The total daily dosage for children may be calculated on the basis of body weight or body area using approximately 0.25 mg/kg/day (0.11 mg/lb/day) or 8 mg per square meter of body surface (8 mg/m 2 ). In small children for whom the calculation of the dosage based upon body size is important, it may be necessary to use cyproheptadine syrup to permit accurate dosage. Age 2 to 6 years: The usual dose is 2 mg (1/2 tablet) two or three times a day, adjusted as necessary to the size and response of the patient. The dose is not to exceed 12 mg a day. Age 7 to 14 years: The usual dose is 4 mg (1 tablet) two or three times a day, adjusted as necessary to the size and response of the patient. The dose is not to exceed 16 mg a day.
