Why is this medication prescribed?

Chlorpheniramine is an antihistamine medication that is commonly prescribed to relieve symptoms associated with allergies, such as hay fever, allergic rhinitis, and urticaria (hives). It works by blocking the effects of histamine, a substance produced by the body during an allergic reaction. Histamine is responsible for causing symptoms like sneezing, itching, runny nose, watery eyes, and hives.

Chlorpheniramine can help alleviate these symptoms by reducing the effects of histamine, providing relief from allergic reactions. It is often used to manage seasonal allergies, such as those triggered by pollen, as well as allergies to substances like pet dander, dust mites, and mold.

Additionally, Chlorpheniramine may be prescribed to relieve symptoms associated with the common cold, such as sneezing and congestion. However, it is important to note that Chlorpheniramine may cause drowsiness as a side effect, so it is often used in formulations that are specifically designed for nighttime use or when sedation is desired, such as for the relief of cough and cold symptoms before sleep.
