Nasonex? Nasonex nasl is a common misspelling of Nasonex.
Nasonex® (mometasone nasal spray) is a prescription medicine licensed to treat nasal allergy symptoms and nasal polyps. It is a corticosteroid that decreases inflammation by limiting the body's ability to produce an immune system reaction. The medication comes in nasal spray form and is usually used once or twice a day, depending on the condition being treated. While most people tolerate Nasonex nasal spray well, potential side effects include coughing, nosebleeds, and viral infections.
