What Experts Say

Chlorpheniramine is a first generation antihistamine. It blocks histamine, the chemical that causes sneezing, itching and watery eyes during an allergic reaction. It is found in many cold and allergy products, so patients should check labels to avoid taking two antihistamines together.

It also dries nasal secretions, so it is often included in cold remedies. A common side effect is drowsiness because it crosses into the brain. The sedating effect often fades after a few days of regular use, but alcohol can bring it back strongly.

Newer antihistamines such as cetirizine or loratadine cause less sleepiness, but chlorpheniramine remains useful, especially at night. It should be used cautiously in older adults and in people with glaucoma or an enlarged prostate. If symptoms last more than a week or involve wheezing or fever, a doctor should examine the patient.
