Nasonex nasal spray: practical guide for use, dose and safety
Nasonex nasal spray (mometasone furoate) is a prescription steroid spray used to treat nasal allergy symptoms and nasal polyps. It reduces swelling and inflammation inside the nose so you can breathe easier and have fewer sneezes, itches, and runny noses. Many people use it for seasonal allergic rhinitis, perennial allergies, and to help control polyp-related congestion. The spray works locally in the nose and usually takes a few days to start helping; full benefit can take up to two weeks.
How to use Nasonex nasal spray
Before you start, blow your nose gently to clear the passages. Shake the bottle, remove the cap, and prime the pump if it's the first use or after a long pause. Close one nostril with a finger, insert the tip into the other nostril, aim slightly away from the septum, and press the pump while breathing in gently. Repeat in the other nostril if your dose requires it. Common adult dosing is one or two sprays per nostril once daily depending on the product and condition; children often use a lower dose—follow the exact instructions from your doctor or the leaflet. Don't sniff hard right after spraying; a gentle inhalation is enough. If you miss a dose, use it as soon as you remember but don't double up the next time.
Side effects, precautions & when to call a doctor
Most side effects are mild. You may notice nose irritation, dryness, a slight burning, or a small amount of nosebleed. Less common effects include headaches or throat irritation. If you develop signs of infection, severe nosebleeds, worsening vision, or persistent severe headaches, contact your healthcare provider. Steroid sprays can rarely affect growth in children if used long term at high doses, so regular medical review is sensible for kids on maintenance therapy.
Interactions and safety tips: Nasonex works mainly inside the nose, so systemic interactions are limited. Still, tell your doctor if you use oral steroids, antifungal drugs, or immunosuppressants. If you have recent nasal surgery, a septal perforation, or active nasal infections, get medical advice before starting. Pregnancy and breastfeeding should be discussed with your clinician—mometasone is often considered when benefits outweigh risks but always check with your provider.
Storage and practical notes: Keep the bottle tightly closed at room temperature away from heat and direct sunlight. Replace the cap after use and keep it out of children’s reach. Do not stop suddenly if you were prescribed Nasonex as part of a plan—follow your prescriber’s plan for stopping. If symptoms don’t improve after a few weeks, or you rely on the spray more than expected, book a review.
If you’re unsure about the dose or notice troubling symptoms, call your pharmacist or doctor. A quick check can prevent small problems from getting worse.
Small tips: try to use Nasonex at the same time each day to build a routine. Avoid using other nasal steroids without advice. A humidifier can ease nasal dryness. Always check the expiry date and don’t share your spray ever.
