Why is this medication prescribed?

Chlorpheniramine is an antihistamine medication that is commonly used to treat allergy symptoms. It works by blocking the effects of histamine, a substance in the body that is involved in allergic reactions. Histamine can cause itching, sneezing, runny nose, and watery eyes, among other symptoms. Chlorpheniramine helps alleviate these symptoms by preventing histamine from binding to its receptors.

Chlorpheniramine may be prescribed for various allergic conditions, such as:

• Allergic rhinitis: This condition involves inflammation of the nasal passages due to allergens like pollen, dust, or animal dander.
• Allergic conjunctivitis: Inflammation of the conjunctiva (the membrane covering the white part of the eye) caused by allergens.
• Allergic skin reactions: It can be used to relieve itching and hives caused by allergic reactions.
