Mometasone is sprayed into the nose to help relieve the stuffy nose, irritation, and discomfort of hay fever and other allergies. In Canada, mometasone can also be used along with certain antibiotics to treat sinusitis. In deciding to use a medicine, the risks of using the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
