How Chlorpheniramine + Naphazoline works
Chlorpheniramine + Naphazoline is an anti-allergic and decongestant combination.
Chlorpheniramine is an antihistamine. It works by blocking histamine receptors in the body. Histamine is a chemical released during an allergic response, causing symptoms such as itching, redness and swelling. By blocking the effects of histamine, chlorpheniramine reduces these symptoms.
Naphazoline is a decongestant. It functions by constricting (narrowing) blood vessels in the eyes. This action decreases redness, swelling, and congestion caused by allergies or irritation.
Put together, these two components work in tandem to temporarily alleviate the symptoms of allergic conditions affecting the eyes, like allergic conjunctivitis.
