Answer: Nasonex (mometasone furoate) is a good choice for the treatment of nasal allergies. Nasonex is a prescription nasal steroid spray indicated for the treatment of seasonal allergic rhinitis and perennial allergic rhinitis in adults and children two years of age and older. Nasonex delivered as 50 micrograms of mometasone furoate per spray, with the correct dosage being one spray per nostril once daily for children two to 11 years of age, and two sprays per nostril once daily in adults and children 12 years and older. Nasonex is also approved for the treatment of nasal polyps in adults at a dose of two sprays per nostril twice a day.
