› Long-term use of Nasonex (Mometasone) can increase your chances of getting thrush in the nose and throat. Your doctor will check your nose and throat if you have to be on this medication for a long time. Also, tell your doctor if you notice pain in the nose and throat with redness and white patches.
Upsides and benefits
› Works to clear nasal congestion and helps you breathe better.
› Helpful in relieving congestion-related headaches.
› Has fewer side effects than other decongestants like pseudoephedrine.
› It doesn't raise your blood pressure and heart rate as much, or cause as much trouble falling asleep.
› Doesn't give you rebound congestion (worse symptoms when you stop taking it) like nasal spray decongestants do.
› First-choice medication for treating runny and stuffy noses caused by allergies. It works by reducing inflammation in the nose.
› Because it's used directly where the inflammation is happening, it has fewer side effects than oral steroids do and has a lower chance of causing withdrawal symptoms once the medication is stopped.
› Can be used as needed to help control symptoms in people age 13 years or older.
› Available as a generic, which is cheaper.
Downsides and risks
› Phenylephrine doesn't last as long as other decongestants like pseudoephedrine (Sudafed).
› You shouldn't use it if you have high blood pressure.
› Can make your heart race or make you feel anxious and restless.
› Shouldn't use it before you want to sleep.
› Not as effective after using it for 4 days in a row.
› Needs to be primed 10 times before it can be used, or re-primed if not used for more than 2 weeks.
› Doesn't have a counter on it, so it can be hard to remember how many sprays are left (each bottle has 120 sprays).
› Since the medicine in Nasonex (Mometasone) is a steroid, it can slow down your healing process if you've hurt your nose or had nose surgery.
