What Experts Say

Chlorpheniramine is a first generation antihistamine that blocks histamine H1 receptors throughout the body. Since histamine is the chemical responsible for sneezing, itching, and a runny nose during an allergic reaction, blocking its receptor quickly reduces these symptoms.

Because first generation antihistamines like chlorpheniramine cross into the brain more easily than newer allergy medicines, they commonly cause drowsiness and slowed reaction time. This is why many guidelines recommend using it only when needed rather than for continuous daily allergy control.

Its anticholinergic activity, which also contributes to drowsiness, explains why chlorpheniramine can cause dry mouth, blurred vision, constipation, and urinary difficulty, particularly in older adults. Many prescribing guidelines list first generation antihistamines among medicines that older adults should generally avoid or use cautiously, since anticholinergic effects can worsen confusion and fall risk in this age group.
