Why is this medication prescribed?

Chlorpheniramine is an antihistamine medication that is commonly used to relieve symptoms associated with allergies, such as hay fever, allergic rhinitis, and allergic conjunctivitis. It works by blocking the action of histamine, a substance in the body that is involved in allergic reactions. Histamine can cause symptoms like sneezing, itching, watery eyes, and a runny nose.

Chlorpheniramine is often found in over-the-counter (OTC) allergy medications and is sometimes combined with other active ingredients, such as decongestants or pain relievers, to provide comprehensive relief from allergy symptoms.

How should this medicine be used?

Here are general guidelines on how Chlorpheniramine is commonly used:

• Read the Label: Always read and follow the instructions on the medication label. Different products may have different formulations, so it’s important to use the specific product as directed.
