[gotcha] Recommending oral phenylephrine \(Sudafed PE, DayQuil, NyQuil PE\) as a nasal decongestant

Do not suggest oral phenylephrine for nasal congestion; the evidence shows it is no better than placebo. For congestion, suggest intranasal sprays \(short-term oxymetazoline\), pseudoephedrine where available, or non-drug measures; flag hypertension/heart-disease cautions.

Journey Context:
Oral phenylephrine is one of the most common OTC ingredients, but after an FDA advisory committee unanimously found it ineffective and the FDA issued a proposed order to remove it from the OTC monograph, the standard of care changed. Many product labels still imply decongestant efficacy. Agents must not parrot brand claims; pseudoephedrine is effective but restricted, and topical decongestants work but carry rebound-congestion limits.
