Phenylephrine is a nasal decongestant that provides relief from nasal discomfort caused by colds, allergies, and hay fever. It belongs to a class of drugs called vasopressors, and it works by 2/5. Neo-Synephrine (phenylephrine hydrochloride ophthalmic solution) is a vasoconstrictor (constricts the veins) and mydriatic (dilates the pupils), and the over-the-counter strength is used to relieve redness, burning, irritation, and dryness of the eye caused by wind, sun, and other minor iption-strength Neo-Synephrine is used to constrict blood vessels in the eye and .
Uses. Phenylephrine is used for the temporary relief of stuffy nose, sinus, and ear symptoms caused by the common cold, flu, allergies, or other breathing illnesses (e.g., sinusitis, bronchitis.

Phenylephrine is a medication primarily used as a decongestant, to dilate the pupil, to increase blood pressure, and to relieve hemorrhoids. While marketed as a decongestant, taken by mouth at recommended doses it is of unclear benefit for hay fever. It can be taken by mouth, given by injection into a vein or muscle, or applied to the ncy category: US: C (Risk not ruled out).
