Nasonex is a brand name for mometasone nasal, according to Drugs.com. It is a corticosteroid with the chemical formula of C27H30Cl2O6 and treats sneezing, rhinitis and congestion caused by allergies. Adult patients also take Nasonex to treat nasal polyps.
Before taking Nasonex, patients need to consult with their doctors if they have recently been ill or have had an infection. This is because Nasonex can interfere with the levels of blood cells that fight infection, explains Drugs.com. Patients who suffer from glaucoma, herpes infection of the eyes, tuberculosis or nasal ulcers should also be careful before they take Nasonex. The same is true of people who have recently had surgery on or injury to their noses.
Before doctors prescribe Nasonex, patients should also tell them if they take any other medications, vitamins or supplements, reports Drugs.com. It is possible that Nasonex can harm an unborn baby, so women who are pregnant should consult with their doctors before taking the drug, as should nursing mothers.
Nasonex can have several side effects, notes Drugs.com. They include severe nosebleeds that don't stop, nasal ulcers that don't heal, wheezing, problems with vision or symptoms that feel like an attack of flu. Other side effects include headache, cough, sore throat, stuffy nose, and pains in the muscles or joints. Other people experience nausea or white patches inside the nose.
