How To Use Nasonex

How to Take Nasonex: Step‑by‑Step Usage Guide

Follow these steps exactly to ensure each dose reaches the nasal mucosa effectively.

1. Prepare: Gently shake the bottle and remove the dust cap.
2. Prime (first use or after 14 days): Hold the bottle upright, point the nozzle away from you, and pump 10 times until a fine mist appears. If you haven’t used it for 14 days or more, re‑prime with 2 sprays.
3. Clear your nostrils: Blow your nose gently to remove any blockage.
4. Position the nozzle: Close one nostril with a finger. Tilt your head slightly forward, keeping the bottle upright. Insert the nozzle into the open nostril.
5. Spray: Breathe in gently through your nose and simultaneously press down once on the pump to release one spray.
6. Repeat: If a second spray is needed in the same nostril (as per dose), repeat step 5. Then repeat steps 4‑5 for the other nostril.
7. After use: Wipe the nozzle with a clean tissue and replace the dust cap.

Cleaning Your Nasonex Spray

Clean the nozzle at least once a week to prevent blockage:

• Remove the dust cap and gently pull off the nozzle.
• Wash the nozzle and dust cap in warm water, then rinse under running tap.
• Allow them to dry in a warm place. Do not use a pin or sharp object to unblock – this will damage the nozzle.
• Once dry, push the nozzle back onto the bottle and replace the dust cap. Re‑prime with 2 sprays before next use.

Nasonex Dosage Guide: Adults, Children and Nasal Polyps

Always follow your doctor’s prescription. The doses below are based on the official SmPC and PIL.

Onset and full benefit: Some patients notice relief within 12 hours after the first dose, but maximum effect may take 2‑4 days. Regular daily use is essential.

Who Should Use Nasonex: Indications and Candidates

Nasonex is suitable for:

• Adults and children (≥3 years) with symptoms of seasonal (hay fever) or perennial allergic rhinitis – sneezing, itching, blocked or runny nose.
• Adults (≥18 years) with nasal polyps – to reduce polyp size and relieve nasal obstruction.

It can be used prophylactically before exposure to known allergens (e.g., pollen season) to prevent symptoms.

Who Should Not Use Nasonex: Contraindications and Precautions

Do not use Nasonex if:

• You are allergic to mometasone furoate or any of the excipients (see section 6 of PIL).
• You have an untreated nasal infection (e.g., herpes simplex, bacterial/fungal infection). The infection must be treated first.
• You have recently undergone nasal surgery or injured your nose – wait until healing is complete.

Consult your doctor before use if:

• You have or have had tuberculosis.
• You have any other infection (systemic or local).
• You are taking other corticosteroid medicines (oral, injectable, or other nasal sprays).
• You have cystic fibrosis.
• You are immunocompromised or have been in contact with measles/chickenpox.

Using Nasonex with Food, Other Medicines, and Special Conditions

With or without food: Nasonex is a nasal spray; food does not affect its absorption or action. Use it at any time of day, consistently.

Interactions with other medicines: Always inform your doctor about all medications you take. Particular caution with:

• Other corticosteroids (oral, injectable, nasal) – risk of cumulative systemic effects.
• HIV medications (ritonavir, cobicistat) and strong CYP3A4 inhibitors – may increase systemic exposure to mometasone; monitor closely.

Other conditions: If you develop an infection in your nose or throat during treatment, consult your doctor. If you experience persistent nasal irritation, stop use and seek advice.

Special Conditions: Pregnancy, Breastfeeding and Additional Advice

Pregnancy: There is limited or no data on the use of Nasonex in pregnant women. Mometasone furoate should only be used during pregnancy if the potential benefit justifies the potential risk to the foetus. Uncontrolled allergic rhinitis can also affect pregnancy, so discuss with your doctor.

Breastfeeding: It is not known whether mometasone furoate is excreted in human milk. A decision should be made whether to discontinue breastfeeding or to discontinue the medicine, considering the importance of the medicine to the mother.

Driving and machines: No known effects.

Benzalkonium chloride: Nasonex contains 0.02 mg per spray of this preservative, which may cause nasal irritation or swelling with prolonged use.
