About Nasonex

The information provided in the summary table is for reference only. It is important to consult a qualified healthcare professional before starting any allergy relief treatment, including Nasonex.

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 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.

What is contained in Nasonex nasal spray?

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.

The inactive ingredients which make up the aqueous spray are:

  • dispersible cellulose
  • citric acid monohydrate (anhydrous citric acid)
  • polysorbate 80
  • glycerol
  • sodium citrate
  • purified water

The preservatives in Nasonex is benzalkonium chloride which may cause nasal irritation.

Alternatives to Nasonex

The following are the most common alternatives to Nasonex for the treatment of hay fever symptoms:

  • Neoclarityn

It contains the active ingredient desloratadine, a second-generation antihistamine. Neoclarityn is not suitable for individuals who are pregnant or breastfeeding.

  • Telfast

It contains the active ingredient fexofenadine, a second-generation antihistamine.

What dose should I choose?

For 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 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.

Side effects

Like all medicines, after using Nasonex Nasal Spray you may experience a number of side effects. Common side effects and how to overcome symptoms include:

  • Unusual smell: this side effect should wear off over time
  • Headaches: refrain from drinking too much alcohol, rest well and drink plenty of water to stay hydrated
  • Sneezing: once the nasal spray begins working this side effect should wear off
  • Nosebleeds: you should stop using Nasonex Nasal Spray immediately and speak to a GP or pharmacist.

If any of these side effects worsen you should stop using Nasonex Nasal Spray and seek medical advice as soon as possible.

Can children use Nasonex Nasal Spray?

Nasonex Nasal Spray can be used by children over the age of 3 years old for allergy relief from allergies such as hay fever.

Can pregnant or breastfeeding women use Nasonex Nasal Spray?

If you are pregnant or breastfeeding, you should consult with a GP, pharmacist or midwife before using Nasonex Nasal Spray.
