Overview
- Using nasal decongestant sprays for longer than a week can cause rebound congestion, known as rhinitis medicamentosa, and may lead to dependence.
- An RPS survey of 300 pharmacists found 59% believe the public is unaware of the seven‑day risk.
- Nearly three‑quarters (74%) of pharmacists said packaging should more clearly state the seven‑day limit.
- Almost two‑thirds (63%) reported intervening in cases of suspected overuse in their pharmacies.
- The RPS advises following pack instructions and speaking to a pharmacist if congestion lasts beyond seven days, noting sprays are for short‑term relief from colds, allergies and sinusitis.
