Product information

Nasacort nasal spray is manufactured by Sanofi and is a corticosteroid that uses the active ingredient triamcinolone acetonide. The spray is usually applied twice into each nostril once a day to reduce the inflammation associated with an allergic reaction. In some countries Nasacort is marketed as Nasacort AQ, or Nasacort Allergy 24HR.

  1. Easily-administered nasal spray
  2. Effective relief from allergic rhinitis
  3. Ideal for those who don’t like pills

Nasacort provides effective relief for those with seasonal and year-round nasal allergies. Seasonal allergic rhinitis, commonly known as hay fever, is where the body recognises pollen from trees, plants and weeds as potential threats or allergens. Whereas perennial allergic rhinitis can be caused by allergens throughout the year; such as dust mites and animal dander. Both types of allergies cause unpleasant symptoms. Each time the body comes into contact with the allergen it tries to fight it as though it is fighting an infection, by producing high numbers of antibodies. This can make the affected person feel as though they have a common cold with symptoms such as sneezing, itching and a runny or blocked nose.

Allergic rhinitis is thought to affect around 20 per cent of the UK’s population. Anyone can contract the condition regardless of age or gender. There is no cure for nasal allergies, although some people may experience slight improvement over time, it is unlikely that the problem will completely resolve. Once you establish that you have an allergy you should try, where possible, to avoid the allergen that triggers your symptoms. This is not always an easy option and you may need to regularly rinse your nose with a saltwater solution to flush out any allergens caught in the passages.

Corticosteroids such as Nasacort are available to treat more severe rhinitis symptoms. The active ingredient triamcinolone acetonide reduces inflammation in the nasal passages. The cells in the nose absorb the medication preventing the release of chemicals that usually cause the allergic reaction; thus avoiding the unwanted symptoms. The spray can take around three days to become effective and should be administered routinely whilst the allergen is still present.

Here at we know how frustrating it can be to cope with allergic rhinitis. That’s why we’ve made it easy for you to buy Nasacort treatment from our online pharmacy. All you need to do is select the product and complete our simple medical survey. Your answers will then be reviewed by a GMC-registered doctor or a GPhC-registered prescriber. Following approval a prescription is passed to our UK-based pharmacy who will dispense your item and deliver it to your door via next-day courier service.
