What Experts Say

Doctors describe chlorpheniramine as one of the oldest and most trusted antihistamines used to control allergy symptoms. It works by blocking histamine, the chemical the body releases during an allergic reaction, which is why it eases sneezing, itching and watery eyes so quickly.

Pakistan sees high pollen counts, dust and smog for much of the year, which makes allergic rhinitis and skin itching very common complaints at general physician clinics. Chlorpheniramine remains a first line option because it is inexpensive, effective and has decades of safety data behind it.

Experts do caution that this medicine causes noticeable drowsiness compared to newer antihistamines, so it should not be taken before driving or operating machinery. It is best used at night or when rest is possible, and children, elderly patients and pregnant women should check with a doctor first. Anyone with asthma, glaucoma or an enlarged prostate should also seek medical advice before starting it.
