Nasonex

What is Nasonex nasal spray used for?

Nasonex nasal spray is used to treat nasal allergies (allergic rhinitis), such as hayfever. The active ingredient of Nasonex is a corticosteroid (steroid) called mometasone furoate.

Unlike other allergy treatments, such as antihistamine tablets, Nasonex works directly in the nose to reduce and manage symptoms such as sneezing, itching, a blocked nose or a runny nose.

While you cannot get Nasonex nasal spray over the counter, you can order Nasonex online from Prescription Doctor's UK pharmacy. To begin your order, simply complete our short online medical questionnaire for one of our doctors to review.

If your order is approved before 3pm on a weekday, our UK pharmacy will dispense and dispatch your item the same day via a discreet, next-day delivery service.

What is allergic rhinitis?

Allergic rhinitis is an immune response to allergens such as pollen (known as hayfever), pet fur and dander, or dust. To those who are sensitive to these allergens, the presence of these within the nostrils causes cells in the walls of the nostrils to release chemicals called histamines.

These chemicals cause inflammation in the mucous membranes of the nose and eyes, resulting in the symptoms of rhinitis. These symptoms include:

• Coughing
• Itchy eyes
• Itchy nose
• Runny nose
• Sneezing
• Sore throat
• Watery eyes

For some people, avoiding their allergic triggers is effective at keeping their symptoms under control. People with hayfever may stay indoors when the pollen count is high, for example. But such precautions may not be possible by everyone.

Allergies can also affect other conditions, including asthma, which can cause people with asthma to use their inhalers more frequently. If you feel your allergies to affect other health conditions, speak to your doctor or a pharmacist for advice.

If it is not possible for you to avoid your triggers, and your symptoms are disrupting your sleeping pattern or concentration, Nasonex nasal spray may help you.

If you suffer from rhinitis but are not sure what triggers your symptoms, speak to your GP about getting an allergy test. This will help to identify possible triggers of your condition so that you can avoid them.

You should speak to your doctor or a pharmacist for advice on taking treatments for allergies, including over-the-counter hayfever treatments.

How does Nasonex work?

Nasonex contains a corticosteroid (steroid) called mometasone furoate.

Mometasone furoate prevents cells in the nose from releasing chemicals which cause inflammation and the symptoms of nasal allergies.

By blocking the inflammatory response in the nose, the symptoms clear up.

Nasonex does not immediately relieve the symptoms of allergic rhinitis.

You need to use Nasonex nasal spray regularly for a period of time before you will notice a change in your allergy symptoms.
