What is Nasonex and what is it used for?

Nasonex is used to reduce the irritation and swelling in your nose. This helps to relieve sneezing, itching, and a runny or blocked nose caused by hay fever or other allergies. Nasonex contains mometasone furoate, part of a group of medicines known as corticosteroids. Corticosteroids are a man-made version of a hormone that your body naturally makes. They are not the same as anabolic steroids.

How does Nasonex work?

The active ingredient of Nasonex(mometasone furoate) absorbs into the lining of your nose and stops the production of the chemicals that cause allergic reactions.

How long does Nasonex last?

You can use Nasonex for up to 3 months. However, your doctor or pharmacist may recommend you use it for longer. You should let your doctor know if you do not feel better after using it for 2 weeks, as they may want to change your treatment. 

How long does Nasonex take to work?

Some people find that Nasonex starts relieving symptoms within 12 hours of their first dose. However, you should continue to use Nasonex regularly to get the full benefit of the treatment.
If you get hay fever every year and have difficulty controlling your symptoms, your doctor or pharmacist may advise you to begin using Nasonex before the pollen season starts to prevent symptoms from even starting. 

How effective is Nasonex?

Nasonex is an effective way to reduce hay fever symptoms. If your symptoms do not go away after using the spray for several days, you should speak to your doctor or pharmacist.
