Uses for mometasone

Mometasone nasal spray is used to treat and prevent the symptoms (eg, stuffy or runny nose, itching, sneezing) of seasonal (short-term) and perennial (year-round) allergic rhinitis (hay fever). This medicine is also used to treat nasal polyps in adults.

Mometasone belongs to the family of medicines known as corticosteroids (cortisone-like medicines). It works by preventing certain cells from releasing substances that cause an allergic reaction.

This medicine is available only with your doctor's prescription.
