MOMELO 120 SPRAYS is a nasal spray available in a bottle containing 120 metered doses. 1 It typically contains a combination of two active ingredients: mometasone furoate and olopatadine hydrochloride. Mometasone furoate is a corticosteroid that reduces inflammation in the nasal passages, while olopatadine hydrochloride is an antihistamine that helps relieve allergy symptoms such as runny nose, sneezing, and itching. This combination is used to treat symptoms of seasonal allergic rhinitis (hay fever) and perennial (year-round) allergic rhinitis in adults and children (the specific age range may vary depending on the formulation). It works by preventing the release of substances in the body that cause allergic reactions, thereby relieving nasal congestion, discharge, itching, and sneezing. 2 The usual dosage for adults and adolescents 12 years and older is two sprays in each nostril twice daily, while for children 6 to 11 years old, it is typically one spray in each nostril twice daily, though these dosages can vary based on the specific product and medical advic
