What is Nasonex

Nasonex nasal spray is used to treat allergic rhinitis, which is an inflammation of the inside of the nose triggered by allergens like dust, pollen and mould. Nasal allergies are common affecting around one in five people in the UK and they can cause a blocked or runny nose, sneezing and itchiness. Nasonex nasal spray contains the active ingredient mometasone, which is a type of corticosteroid.

Can I buy Nasonex Nasal Spray Online?

Nasonex is a prescription medication, so it can only be bought online with one via the Click Pharmacy website.

To purchase your medication online, you simply select your treatment and fill out a short health questionnaire so that our in-house doctors can assess whether this is the right form of treatment for you and therefore issue you with a prescription so that the pharmacy team at click pharmacy can dispense your medication.

Why choose Nasonex Nasal Spray?

The symptoms of allergic rhinitis and hay fever can be irritating and, in some cases, distressing. Severe cases can interfere with people’s everyday lives and cause disruption to their sleep patterns. Mometasone furoate is one of a group of medicines known as corticosteroids, and nasal sprays which contain it, such as Nasonex, can offer effective relief from the symptoms of such allergies, helping you to get on with your life without suffering and discomfort.

What dose should I choose?

in adults and children over 12 years old, the usual dose is one or two sprays into each nostril (as discussed with your doctor) once a day which equates to around a 200mcg dose. This should help to bring your symptoms back under control though your doctor may recommend you increase this to four sprays in each nostril if you do not find that you are feeling better.

For children between 3 and 11 years, the dose is one spray per nostril once a day, but this should be discussed with a doctor before going ahead to ensure that Nasonex will help ease the symptoms with which they are suffering.

Detailed dosage instructions are provided with the spray, and you can find out more about how to use the treatment by contacting your doctor or getting in touch with our specialists at Click Pharmacy.

How effective is Nasonex Nasal Spray?

Nasonex is an effective treatment of allergic rhinitis and hay fever and helps to get the symptoms under control by reducing swelling within the nose. In turn, this relieves sneezing and blocked or runny noses.

In some cases, certain medications may reduce or heighten the effects of Nasonex, and as such, it is important to discuss any other medications and supplements with your doctor before starting to use it.

The effects of the medication should be noticed after around two days of use, but the full effects of the drug may take anywhere up to 14 days to kick in. As such, if you are using Nasonex to help you with seasonal allergies, then it may be recommended that you begin taking it between two and four weeks prior to pollen season.

How should I take Nasonex Nasal Spray?

Before using the spray for the first time, make sure you shake the container well. You should then actuate the pump around 10 times or until a steady spray is achieved. Once you have prepared the spray, you can administer the correct dosage based on the instructions provided with the treatment.

Blow your nose before using the product. Close the nostril you will not be spraying with your finger and tilting your head forward slightly, place the applicator into the open nostril and spray the desired number of pumps into it before repeating this process on the other side. Avoid re-blowing your nose for 15 minutes after application, and if possible, breathe through your nose gently.

Shake before each subsequent use, and if the pump has not been used for two weeks or longer, make sure you re-prime it by actuating it a couple of times. Note that this medicine is intended for use in the nose. You must not administer it into your mouth, and you should take care to avoid your eyes.

How does Nasonex Nasal Spray work?

Mometasone is a synthetic corticosteroid, and it helps to control inflammatory responses. When sprayed into the nose, it is absorbed into the cells lining the nasal passage, and it decreases inflammation. It can take a few days for the treatment to take full effect, so if you are aware that you are going to be exposed to allergens, it helps if you start using the treatment in advance.

Is it safe to use a nasal spray at the same time as oral antihistamines?

It depends on your symptoms, and your GP or doctor at Click Pharmacy will advise you on the best route for you with regard to taking oral antihistamines alongside Nasonex. Generally, you may be advised to stop taking your oral medication once using Nasonex but ensure you get this confirmed by a medical professional before going ahead.

The active ingredient in Nasonex is Mometasone furoate monohydrate. It is part of the corticosteroid family, which help to bring down inflammation and which, in the case of Nasonex, is in the nose.
