In general, chlorpheniramine can be dosed by age or by weight for children. Based on weight, a standard recommended dose is 0.35 mg per kg per day (0.16 mg per pound per day), divided into smaller doses given every four to six hours. Based on age, the recommended chlorpheniramine dose is as follows:
  • Age 2 to 6 -- 1 mg every 4 to 6 hours, not to exceed 6 mg in 24 hours
  • Age 6 to 12 -- 2 mg every 4 to 6 hours, not to exceed 12 mg in 24 hours
  • Age 12 and older -- usual adult dosing.
It should be noted that medications (including chlorpheniramine) should not be used to treat the common cold in children under four years old, as cold medications have not been shown to be effective or safe in this age group.
