Nasonex

What is Nasonex?

Nasonex is a corticosteroid spray that reduces inflammation and swelling. It’s primarily used for allergic problems like rhinitis (hay fever).

Nasal infections are often caused by the bacteria Staphylococcus aureus, and depending on the severity of your symptoms, you might need antibiotics.

Although Nasonex can’t treat the infection, it can help relieve the symptoms you get with an infection, like nasal congestion and swelling.

How does Nasonex work?

Nasonex (mometasone) is a corticosteroid that works by reducing inflammation in the nasal passage. It suppresses the immune system’s inflammatory response, by stopping cells that cause inflammation from working. In doing this, it helps to relieve symptoms like nasal congestion and runny nose.^[1]

It’s important to know Nasonex doesn’t treat the infection, but relieves the symptoms.

What doses of Nasonex are there?

Nasonex is only available in one dose of 50mcg. The typical dosage is one to two sprays in each nostril a day, but you should always take it as directed by the person who prescribed it for you. Your doctor might gradually lower your dose as your symptoms improve.

How to use Nasonex

Before using Nasonex, you’ll need to prime the bottle so it produces a fine mist. To prime it:

1. Shake the bottle a few times. 
2. Place your fingers on the nozzle. 
3. Pump the bottle a few times until a fine mist is produced. 

To use Nasonex:

1. Shake the bottle and remove the cap. 
2. Gently blow your nose. 
3. Close one nostril and place the nozzle at the tip of the other nostril. 
4. While breathing in slowly, pump the bottle once. 
5. Repeat for the other nostril. 

How long does Nasonex take to work?

Some people may feel relief within 12 hours, while others might take a few days to notice an improvement in their symptoms. If your symptoms do not improve after a week or if they worsen, inform your doctor.

I sprayed too much Nasonex, now what?

Like all medications, using more than the prescribed amount can increase the risk of side effects. But if you spray slightly more than you should with this treatment, this risk is very low. Nasonex only contains a small amount of corticosteroids and is applied directly to the site of the infection, so it shouldn’t affect you systemically because it’s not being taken up into the bloodstream.
