Nasonex Dosage/Direction for Use

After initial priming of the NASONEX Aqueous Nasal pump (10 actuations, until a uniform spray is observed), each actuation delivers approximately 100 mg of mometasone furoate suspension, containing mometasone furoate monohydrate equivalent to 50 micrograms mometasone furoate. If the spray pump has not been used for 14 days or longer, it should be reprimed with 2 actuations, until a uniform spray is observed, before next use.
Shake container well before each use.
Seasonal allergic or perennial rhinitis: Adults (including geriatric patients) and adolescents: The usual recommended dose for prophylaxis and treatment is two sprays (50 micrograms/spray) in each nostril once daily (total dose 200 micrograms). Once symptoms are controlled, dose reduction to one spray in each nostril (total dose 100 micrograms) may be effective for maintenance.
If symptoms are inadequately controlled, the dose may be increased to a maximum daily dose of four sprays in each nostril once daily (total 400 micrograms). Dose reduction is recommended following control of symptoms.
Clinically significant onset of action occurs as early as 12 hours after the first dose.
Children between the ages of 2 and 11 years: The usual recommended dose is one spray (50 micrograms/spray) in each nostril once daily (total dose 100 micrograms). Administration to young children should be aided by an adult.
Adjunctive treatment of acute episodes of sinusitis: Adults (including geriatric patients) and adolescents 12 years of age and older: The usual recommended dose is two sprays (50 micrograms/spray) in each nostril twice daily (total dose 400 micrograms).
If symptoms are inadequately controlled, the dose may be increased to four sprays (50 micrograms/spray) in each nostril twice daily (total dose 800 micrograms).
Nasal Polyposis: Adults (including geriatric patients) and adolescents 18 years of age and older: The usual recommended starting dose for polyposis is two sprays (50 micrograms/spray) in each nostril once daily (total daily dose of 200 micrograms). If after 5 to 6 weeks symptoms are inadequately controlled, the dose may be increased to a daily dose of two sprays in each nostril twice daily (total daily dose of 400mcg). Dose reduction is recommended following control of symptoms. If no improvement in symptoms is seen after 5 to 6 weeks of twice daily administration, alternative therapies should be considered.
Efficacy and Safety studies of Nasonex Aqueous Nasal Spray for the treatment of nasal polyposis were four months in duration.
Acute Rhinosinusitis: Adults and adolescents 12 years of age and older: The usual recommended dose for acute rhinosinusitis is two actuations (50 micrograms/actuation) in each nostril twice daily (total daily dose of 400 micrograms).
