GlossaryPhenylephrine

medication that constricts blood vessels to relieve nasal congestion

Phenylephrine is a medication commonly used as a decongestant to relieve nasal congestion caused by colds or allergies. It works by constricting blood vessels in the nasal passages, reducing swelling and making it easier to breathe. Additionally, phenylephrine can be used to increase blood pressure in certain medical situations and is sometimes included in formulations for eye drops to dilate pupils.
