Chlorpheniramine + Phenylephrine is a combination antihistamine and decongestant.
Chlorpheniramine, the antihistamine, works by blocking the action of histamine, a chemical released in the body during an allergic reaction. Blocking histamine helps to reduce allergy symptoms like itching, sneezing, a runny nose, and watery eyes. It also helps to dry up nasal secretions and improve a post-nasal drip (excess mucus dripping down the back of the throat).
Phenylephrine, the decongestant, works by constricting (narrowing) blood vessels in the nasal passages. This reduces swelling and inflammation in the nasal passages. In turn, this can relieve nasal congestion and sinus pressure, making it easier to breathe.
When used together, these two components help reduce symptoms associated with conditions like the common cold, flu, allergies and other respiratory conditions.
