AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
PHENERGAN VC is an oral syrup combining phenylephrine hydrochloride (a decongestant) and promethazine hydrochloride (an antihistamine/anticholinergic agent). This fixed-dose combination is indicated for symptomatic relief of upper respiratory conditions, primarily cough and congestion associated with allergies or colds. The phenylephrine acts as a nasal decongestant while promethazine provides antihistamine and anticholinergic effects.
