[gotcha] Recommending prolonged use of oxymetazoline \(Afrin\) for nasal congestion

If recommending topical nasal decongestants, explicitly cap usage at 3 to 5 days. Warn that exceeding this causes rhinitis medicamentosa \(rebound congestion\), making the original congestion worse and creating physical dependence.

Journey Context:
Agents see 'nasal congestion' and correctly identify oxymetazoline as an effective OTC treatment. However, they often omit the strict 3-5 day limit because the drug's efficacy seems to imply it's safe for the duration of a typical cold. The vasoconstrictor mechanism downregulates alpha-receptors over time, trapping the user in a cycle of dependence that requires steroid tapering to break.
