Chlorpheniramine is an antihistamine active ingredient available in over-the-counter (OTC) medicines that treat hay fever and other respiratory allergies. It may be written as chlorpheniramine or chlorpheniramine maleate, but it is the same active ingredient. Chlorpheniramine can be the only active ingredient in an allergy medicine or it can be found in medicines that relieve other symptoms, such as body aches and pains, or symptoms associated with the common cold.
Chlorpheniramine is approved by the U.S. Food and Drug Administration (FDA) and is safe and effective when used according to the Drug Facts label directions. It is crucial that parents and other caregivers read the Drug Facts label carefully to determine whether the medicine is appropriate for the child they wish to treat. In the case of chlorpheniramine, some medicines may be used in certain children under 6 at a healthcare provider’s direction, while other products should only be taken by adults or children 12 and older.
