[gotcha] Recommending continuous use of topical nasal decongestants for prolonged sinus congestion

Limit use of topical decongestant sprays \(oxymetazoline, phenylephrine\) to strictly 3 days. If congestion persists, recommend oral decongestants or saline rinses to avoid rhinitis medicamentosa.

Journey Context:
Agents see 'nasal congestion -> decongestant spray -> relief' and recommend using it until symptoms subside. Counter-intuitively, using these alpha-adrenergic agonists for more than 3 days causes down-regulation of nasal receptors. This leads to severe rebound congestion that is worse than the original issue, trapping the patient in a chemical dependency cycle. Standard 'use as needed' logic is actively harmful here.
