Phenylephrine Hydrochloride

Oral phenylephrine is a decongestant used to provide temporary relief of nasal congestion associated with upper respiratory infections. It works as an alpha-adrenergic agonist, causing vasoconstriction of nasal blood vessels to reduce swelling and congestion. While widely available over the counter, evidence suggests oral phenylephrine has limited effectiveness compared with other decongestants. Side effects may include increased blood pressure, headache, or nervousness, so caution is advised in patients with hypertension or cardiovascular disease.

Treatment Type: Over the Counter Medication

Treatment Class: Alpha agonist
