Reformulation
Previously, NyQuil Cold/Flu Multisymptom Relief and NyQuil Sinus contained pseudoephedrine (30 mg/15 mL), a nasal decongestant that also formed the active ingredient in Sudafed. Following the passage of the Combat Methamphetamine Epidemic Act in 2006, in the United States all pseudoephedrine-containing medications must be kept behind a pharmacy counter and all purchases must be logged.
Vicks chose to reformulate NyQuil Sinus in 2006, replacing pseudoephedrine with phenylephrine. However, studies have shown that phenylephrine is no more effective than a placebo. As of 2012, the only NyQuil variety which contains pseudoephedrine is Nyquil D.
