Nasonex nasal spray is an inhaled medication that is used to help treat the symptoms of both seasonal and year-round allergies. It’s used by people with allergic rhinitis, sometimes called hay fever. It is also used to treat adults who have nasal polyps.

The active ingredient in this medication is called mometasone. This is a type of medication called a corticosteroid. It helps allergy sufferers by decreasing the amount of inflammation and swelling in their noses. This makes it much easier for the patient to breathe. As a corticosteroid, mometasone keeps specific cells from releasing certain substances that are the cause of the patient’s allergic reaction.

This medication is helpful for preventing and treating allergy symptoms. These can include a runny nose, stuffy nose, sneezing, and itching eyes or nose. Many people get watery eyes or have a sore throat from post-nasal drip. Taking this medication can temporarily alleviate these symptoms and allow patients to be more comfortable. It’s a prescription medication that can also be purchased over the counter in some countries. It’s used every day for the best results. Always follow your doctor’s instructions about how to use it and how often.
