Mometasone nasal spray comes in nasal spray form. It is usually taken once or twice a day, depending on whether it is used to treat allergies or polyps.
Be sure to shake your mometasone nasal spray bottle well before each use.
Blow your nose before each dose. Breathe in gently while spraying mometasone nasal spray into your nose. Do not try to inhale the spray or breathe in too deeply, as mometasone nasal spray works when it comes in contact with the inside surfaces of the nose (not the throat or lungs).
Avoid aiming the spray toward the wall that separates your nostrils (in the middle of your nose, called the nasal septum). Spraying mometasone nasal spray toward the nasal septum increases the risk of nosebleeds. Some people find it easiest to avoid this by holding the bottle in the opposite hand (by using the right hand to spray into the left nostril, and vise versa).
For the medication to work properly, it must be taken as prescribed. Mometasone nasal spray will not work if you stop taking it.
