How is Nasonex taken?

Nasonex is applied via a nasal spray. You should blow your nose gently, shake the container slightly, remove the protective cap and apply it to one nostril at a time using the spray pump. Be careful not to get it in your eyes and mouth.

To get the best results, tilt your head forward slightly and try to aim towards the outside of your nostril, rather than dead centre. Once you’ve sprayed, breath in slowly through your nose and then out through your mouth.

It’s generally recommended to be used several times each day. However, you shouldn’t try and up the dosage or frequency with which you use it without speaking to a doctor first.

You shouldn’t expect instant results, since Nasonex can take a couple of days to become effective and if you’re looking for quick relief - ask your doctor about complementary treatments like nose drops or anti-allergy medication.

What can Nasonex be used to treat?

Nasonex can be used to provide symptomatic relief for allergies and other conditions that cause inflammation (swelling) in the nose.

While it can’t address the root cause of the condition, the active ingredient mometasone mimics the natural hormone cortisol, which reduces the production of inflammation-causing chemicals like histamine and interferes with white blood cells - limiting the immune system’s response to allergens.

What Are The Side Effects of Nasonex?

Most people won’t experience any serious side effects, however, dryness of the nose or throat may occur, alongside nosebleeds and traces of blood in mucus and phlegm.

In rare cases, pain or sores may crop up in the nose and users can experience trouble swallowing or patches of white appearing in their nose and mouth.

It’s also possible for the corticosteroid to be absorbed into the user’s bloodstream, which in rare circumstances can lead to overexposure to the substance, mainly among those who use it in high doses for a long period.

In cases like this, symptoms like intense tiredness, sudden weight loss, headaches, swellings and extreme thirst may develop.

Although rare, it is possible to have an allergic reaction to corticosteroids like Nasonex, so if you experience rashes, itching, breathing problems or intense dizziness - seek urgent medical attention.

Things to avoid

Fortunately, adverse reactions to corticosteroids like those used in Nasonex are few and far between, but you should still make sure to tell your doctor if you’re suffering from any other conditions or are taking any other type of medication.

Some substances that could potentially interact negatively with Nasonex include:

  • Other corticosteroids
  • Other nasal sprays
  • Ceritnib

If you’re worried about potential interactions, be sure to speak to do your doctor before suddenly stopping Nasonex - as this may affect your treatment.

Nasonex and alcohol

While Nasonex doesn’t interact with alcohol, drinking while suffering from allergies may make several symptoms worse and harder to get under control.

Is It Safe to Use Nasonex During Pregnancy?

Nasonex is not regularly prescribed for pregnant women, since some studies have highlighted an increased risk of foetal damage. Similarly, traces of the drug can be passed to newborns via breastfeeding, so it’s commonly advised to steer clear of it until you’ve weaned your child.
