Question: is phenylephrine hydrochloride the same as pseudoephedrine hydrochloride

Answer: No, Phenylephrine is used as an alternative for pseudoephedrine in decongestant medicines due to pseudoephedrine's use in the illicit manufacture of methamphetamine. Its efficacy as an oral decongestant has been questioned, with several recent independent studies finding that it provided no more relief to sinus congestion than a placebo.
