The safety and effectiveness of mometasone furoate nasal spray for prophylaxis of the nasal symptoms of seasonal allergic rhinitis in pediatric patients 12 years of age and older have been established [see Adverse Reactions (6.1) and Clinical Studies (14.1)]. Use of mometasone furoate nasal spray forthis indication is supported by evidence from controlled trials in adult and pediatric patients 12 years of age and older [see Clinical Studies (14.1)]. 

The safety and effectiveness of mometasone furoate nasal spray for the treatment of chronic rhinosinusitis with nasal polyps in pediatric patients less than 18 years of age have not been established. Effectiveness was not demonstrated in one 4-month trial conducted to evaluate the safety and efficacy of mometasone furoate nasal spray in the treatment of chronic rhinosinusitis with nasal polyps in pediatric patients 6 to 17 years of age. The primary objective of the study was to evaluate safety; efficacy parameters were collected as secondary endpoints. A total of 127 patients with chronic rhinosinusitis with nasal polyps were randomized to placebo or mometasone furoate nasal spray 100 mcg once or twice daily (patients 6 to 11 years of age) or 200 mcg once or twice daily (patients 12 to 17 years of age). The results of this trial did not support the efficacy of mometasone furoate nasal spray in the treatment of chronic rhinosinusitis with nasal polyps in pediatric patients. The adverse reactions reported in this trial were similar to the adverse reactions reported in patients 18 years of age and older with chronic rhinosinusitis with nasal polyps. 

Effect of Growth

Controlled clinical studies have shown nasal corticosteroids may cause a reduction in growth velocity in pediatric patients. This effect has been observed in the absence of laboratory evidence of hypothalamic-pituitary-adrenal (HPA) axis suppression, suggesting that growth velocity is a more sensitive indicator of systemic corticosteroid exposure in pediatric patients than some commonly used tests of HPA axis function. The long-term effects of this reduction in growth velocity associated with nasal corticosteroids, including the impact on final adult height, are unknown. The potential for "catch up" growth following discontinuation of treatment with nasal corticosteroids has not been adequately studied. The growth of pediatric patients receiving nasal corticosteroids, including mometasone furoate nasal spray, should be monitored routinely (e.g., via stadiometry). The potential growth effects of prolonged treatment should be weighed against clinical benefits obtained and the availability of safe and effective noncorticosteroid treatment alternatives. To minimize the systemic effects of nasal corticosteroids, including mometasone furoate nasal spray, each patient should be titrated to his/her lowest effective dose.

A clinical study to assess the effect of mometasone furoate nasal spray (100 mcg total daily dose) on growth velocity has been conducted in pediatric patients 3 to 9 years of age with allergic rhinitis. No statistically significant effect on growth velocity was observed for mometasone furoate nasal spray compared to placebo following one year of treatment. No evidence of clinically relevant HPA axis suppression was observed following a 30-minute cosyntropin infusion.

The potential of mometasone furoate nasal spray to cause growth suppression in susceptible patients or when given at higher doses cannot be ruled out.
