What is Mometasone Nasal Spray?
Mometasone Nasal Spray is a steroid-based medicine used to relieve symptoms of hay fever and allergic rhinitis. It helps reduce inflammation inside the nose, easing symptoms such as sneezing, a blocked or runny nose, and nasal itching. It can also be used to treat nasal polyps in adults. The spray is applied directly into the nostrils and works at the source of the problem without causing drowsiness.
How does it work?
Mometasone belongs to a group of medicines called corticosteroids. When sprayed into the nose, it helps reduce swelling, inflammation, and mucus production triggered by allergens like pollen, dust mites, or pet dander. With regular use, it controls symptoms throughout allergy season or year-round in people with persistent allergic rhinitis.
How to use Mometasone Nasal Spray
- Adults and adolescents aged 12 and over: Use 2 sprays in each nostril once daily, preferably in the morning
- Once symptoms improve: Reduce to 1 spray per nostril daily if advised
- Shake the bottle well before each use
- Blow your nose gently before spraying
- Use regularly for best results, especially during allergy season
For allergic rhinitis in children aged 3–11, the usual prescribed dose is one spray into each nostril once daily. Follow the child’s prescription and the leaflet for the supplied spray.
Prime the pump according to the leaflet for your brand before first use and after a break. Tilt your head slightly forward, aim away from the middle wall of the nose and breathe in gently as you spray. Do not sniff hard. Wipe the nozzle after use and clean it as directed; do not unblock it with a pin.
