How Dexchlorpheniramine Maleate Works

Dexchlorpheniramine blocks histamine receptors in the body. Histamine is responsible for many allergy symptoms such as itching, swelling, mucus production, and sneezing.

By preventing histamine from attaching to its receptors, the medication:

Reduces nasal discharge

Relieves itching and eye irritation

Helps control skin allergy symptoms

Decreases sneezing

This medication manages symptoms but does not cure the underlying allergic condition.
