[gotcha] Recommending prolonged use of over-the-counter topical nasal decongestants \(oxymetazoline\) for sinus congestion

Limit use of topical decongestant sprays to a maximum of 3-5 days. Warn that longer use causes rhinitis medicamentosa \(rebound congestion\), making the condition worse.

Journey Context:
A user complains of a stuffed nose. The agent suggests a standard OTC decongestant spray. If the user takes it for a week, they develop rebound congestion due to down-regulation of alpha-adrenergic receptors in the nasal mucosa. Agents must proactively attach the 3-5 day limit warning, as the OTC packaging is often ignored, and the agent's endorsement without a time limit exacerbates the condition.
