How does this medication work? What will it do for me?

This is a combination product that contains two medications: phenylephrine and pheniramine. This medication is used for temporary relief of stuffy nose due to allergies, the common cold, or sinus inflammation.

Phenylephrine belongs to the group of medications called decongestants. It helps clears up the nasal passages by narrowing the blood vessels in the nose.

Pheniramine belongs to the group of medications called antihistamines. It helps to reduce runny nose by blocking histamine, a substance released by the body that causes allergy symptoms.
