Chlorpheniramine: Uses, Side Effects & Brands in Pakistan
Chlorpheniramine (also called chlorphenamine) is an older antihistamine. In Pakistan it is sold as tablets, syrups and injections, and it is an ingredient in many cough and cold mixtures.
How Chlorpheniramine works
Chlorpheniramine blocks histamine, which causes itching, sneezing and swelling in allergic reactions. Unlike newer antihistamines, it enters the brain easily, which is why it makes many people sleepy.
What is Chlorpheniramine used for?
- Hay fever, sneezing and runny nose from allergies
- Itchy skin, hives and insect bite reactions
- Allergic reactions to food or medicines
- Injection: added treatment in severe allergic reactions

Get medical help straight away if you notice signs of a serious allergic reaction, such as swelling of the face, lips or throat, difficulty breathing, or a widespread rash.
Precautions and warnings
- Do not drive or operate machinery if you feel drowsy, and avoid alcohol.
- Check the labels of cough and cold mixtures so you do not take it twice.
