Recommended Dosing for Nasonex (Mometasone Furoate)

The recommended dose of Nasonex (mometasone furoate) is age-dependent: 1 spray per nostril daily for children 2-11 years and 2 sprays per nostril daily for individuals 12 years and older. 1

Age-Specific Dosing Guidelines

  • For adults and children 12 years and older: 2 sprays per nostril once daily (total daily dose: 200 μg) 1
  • For children 2-11 years old: 1 spray per nostril once daily (total daily dose: 100 μg) 1
  • For adults 18 years and older with nasal polyps: 2 sprays per nostril twice daily (total daily dose: 400 μg) 1

Administration Technique

  • Shake the spray bottle well before each use 2
  • Prime the bottle before first use or if not used for one week 2
  • Blow nose gently to clear nostrils before administration 2
  • Close one nostril and insert spray tip into the other nostril, aiming slightly away from the center of the nose 2
  • While sniffing gently, press down on spray nozzle once or twice according to dosing instructions 2
  • Repeat in the other nostril 2

Clinical Efficacy

  • Mometasone furoate nasal spray is effective for both seasonal and perennial allergic rhinitis 1
  • The 200 μg once daily dose has been identified as the optimal dose for adults in clinical trials, with no additional benefit seen at higher doses 3
  • For children 6-11 years, studies have shown that 100 μg once daily is the most appropriate therapeutic dosage, with 200 μg providing no additional benefit 4

Safety Profile and Side Effects

  • Common side effects include headache, viral infection, pharyngitis, epistaxis (nosebleeds), and cough 1
  • Contraindicated in patients with history of hypersensitivity to the medication or its components 1
  • Studies have shown no evidence of hypothalamic-pituitary-adrenal axis suppression at recommended doses 4
  • Mometasone furoate has negligible systemic activity at therapeutic doses 5

Special Considerations

  • For optimal results, use regularly rather than as-needed to maintain symptom control 6
  • Onset of action may be delayed (approximately 12 hours) with maximal efficacy reached in days to weeks 6
  • If symptoms do not improve after one week of use, discontinue and consult a healthcare provider 2
  • For children who need to use Nasonex for longer than two months per year, consultation with a physician is recommended 2
