What Experts Say

Chlorpheniramine is a first generation antihistamine that blocks histamine H1 receptors throughout the body. Histamine is the chemical the immune system releases during an allergic reaction, causing sneezing, itching and swelling. Blocking its receptor calms these symptoms quickly.

Unlike newer antihistamines, chlorpheniramine crosses easily into the brain, which explains why drowsiness is such a common side effect. This sedating quality is sometimes used deliberately in cough and cold formulations to help with sleep during illness, but it also means caution is needed before driving or operating machinery.

Because chlorpheniramine is short acting, it is usually dosed every four to six hours rather than once daily like modern antihistamines. Parents should follow age appropriate dosing carefully in young children, since antihistamine syrups are a common source of accidental overdose in pediatric emergency visits.
