About CHLORPHENIRAMINE

CHLORPHENIRAMINE belongs to the class of medication called 'sedating antihistamine' or 'anti-allergic' primarily used to treat symptoms of allergies such as itching nose/throat, runny nose, sneezing or red/itchy/watery eyes. An allergy occurs when foreign elements known as allergens attacks and invades our body thereby causing the release of histamine (a chemical messenger) that causes swelling, inflammation, redness, itchiness, watery nose, throat, and eyes. 

CHLORPHENIRAMINE contains Chlorpheniramine which works by blocking the action of histamine, a substance responsible for causing allergic reactions. It directly acts on the brain and relieves symptoms of allergies by preventing the release of histamine. It helps to provide relief from symptoms of allergy such as sneezing, running nose, watery eyes, itching, swelling, and congestion or stiffness.

Take CHLORPHENIRAMINE as prescribed by your doctor. You are advised to take CHLORPHENIRAMINE for as long as your doctor has prescribed it for you based on your medical condition.
