What is Hydrocodone Phenylephrine

NOTE: These products are discontinued in the U.S.

Hydrocodone phenylephrine is found in combination products used to relieve cough and nasal congestion due to the common cold and other respiratory infections.

Hydrocodone is an opiate agonist antitussive that relieves cough. Phenylephrine is a sympathomimetic decongestant agent that causes vasoconstriction and decreases congestion.

This combination has been available in marketed products since before 1938.
