About Chlorpheniramine

Chlorpheniramine, universally known in Nigeria as Piriton, is the single most recognisable antihistamine brand in the country. It has been a staple in Nigerian medicine cabinets, hospital pharmacies, and patent medicine stores for decades. Chlorpheniramine is a first-generation antihistamine that works by blocking histamine H1 receptors throughout the body. Histamine is a chemical released by the body during allergic reactions, and it is responsible for symptoms like sneezing, itching, runny nose, watery eyes, and skin rashes. By blocking histamine's effects, chlorpheniramine relieves these symptoms effectively. However, unlike newer antihistamines like cetirizine, first-generation antihistamines like chlorpheniramine freely cross the blood-brain barrier, which is why they cause significant drowsiness — a property that many Nigerians actually exploit, using Piriton as a sleep aid.
