Nasonex is a steroid. It prevents the release of substances in the body that cause inflammation. Nasonex is used nasally to prevent and treat the nasal symptoms of allergies and other seasonal reactions.
Serious side effects from Nasonex nasal are not likely to occur. Stop using Nasonex nasal and seek emergency medical attention if you experience an allergic reaction (difficulty breathing; closing of your throat; swelling of your lips, tongue, or face; or hives). Other, less serious side effects may be more likely to occur. Continue to use mometasone nasal and talk to your doctor if you experience: headache; viral infection; sore throat; bleeding nose; coughing; upper respiratory tract infection; painful menstruation; muscle pain; or stinging or burning of the nose. Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.
Avoid items or activities that you know are allergens for you if they make your symptoms worse. Clean areas where dust or pet fur may aggravate your condition. Avoid exposing yourself to known sources of infection. Stay away from people with chicken pox, measles, or any other type of infectious disease. Your immune system may not be strong enough to fight off an infection while you are using Nasonex nasal.
Before using this medication, tell your doctor and pharmacist about any other drugs you are taking. The use of other oral or inhaled steroids may increase your chance of side effects or overdose. Drugs other than those listed here may also interact with Nasonex nasal. Talk to your doctor and pharmacist before taking any prescription or over-the-counter medicines.
