🤧 Blocked nose from a cold or allergies? Nasal decongestant sprays and drops containing xylometazoline or oxymetazoline should now be used for no more than 5 days.
Using them for longer can cause rebound congestion, where your nose becomes blocked again and symptoms may worsen.
These products remain safe and effective when used as directed, and there are no quality concerns or recalls.
If your symptoms have not improved after 5 days, speak to a pharmacist, GP or other healthcare professional.
Suspected side effects can be reported through the Yellow Card scheme https://brnw.ch/21x24QV
