Using decongestant sprays safely
Decongestant nasal sprays containing xylometazoline or oxymetazoline work within minutes to shrink swollen nasal passages and relieve a blocked nose. The important rule is not to use them for too long: more than five to seven days in a row can cause "rebound" congestion that makes the blockage worse. For longer-term or allergy-related congestion, saline or steroid nasal sprays may suit better.
Frequently Asked Questions
How long can I use a decongestant spray?
No more than about five to seven days in a row, because prolonged use can cause rebound congestion. If your nose is still blocked, ask your pharmacist about alternatives.
How quickly do they work?
They usually start to clear a blocked nose within a few minutes.
Who should be cautious?
They aren't suitable for young children or everyone — check the pack and ask your pharmacist if you have certain conditions or take other medicines.
