Chlortrimeton (called Chlor-Tripolon in Canada), also available as the generic alternative Chlorpheniramine Maleate, is an over-the-counter antihistamine that helps to reduce the symptoms that stem from the release of histamine in the body due to an allergen or irritant. Taking brand name or generic Chlortrimeton can reduce symptoms such as itchy, watery eyes, runny nose or sneezing. Because many of the symptoms are the same as the common cold, Chlortrimeton may also be taken to help treat colds as well.

The generic alternative is not manufactured by the company that makes the brand product.

Chlortrimeton or Chlorpheniramine Maleate may cause side effects such as dry mouth, nausea, drowsiness and excitability. If dry mouth becomes a problem, sucking on ice chips or hard candy may help to alleviate this side effect. Talk to your doctor if you have any questions about the side effects you may experience.
