How does it work?
Beconase hayfever nasal spray contains the active ingredient beclometasone dipropionate (previously spelt beclomethasone in the UK), which is a type of medicine known as a corticosteroid (or steroid). Corticosteroids are hormones that are produced naturally by the adrenal glands and have many important functions, including control of inflammatory responses.
Beclometasone is a synthetic corticosteroid and is used as a nasal spray to decrease inflammation in the nasal passages. (NB. Beclometasone nasal spray is also available without a brand name, ie as the generic medicine.)
People who suffer from nasal allergies (allergic rhinitis) such as hayfever tend to experience a variety of symptoms as a result of their allergy. These include a runny, itchy or blocked nose, sneezing and sinus discomfort. These symptoms are a result of inflammation in the nasal passages.
The nasal inflammation occurs when the nasal passages are exposed to foreign particles (allergens), for example, pollen, dust mites or pet fur. The allergens cause the cells in the nose to release chemicals that produce immune and allergic responses. These result in inflammation in the nasal passages and the symptoms of the allergy.
When administered into the nose, beclometasone is absorbed into the cells of the nasal passages. Here it works by preventing the cells from releasing the chemicals that trigger the allergic response. This stops the allergic reaction from happening so the nasal inflammation is reduced and the symptoms relieved.
The nasal spray will not relieve the symptoms of nasal allergies immediately, and can take two to three days to have its full effect. It is therefore most effective to start using the nasal spray two to three days before you expect to get symptoms, for example before the start of the pollen season, or if you know you are going to be in contact with pets that give you the allergy. For maximum benefit the spray should then be used regularly to keep the nasal inflammation under control.
What is it used for?
Treatment and prevention of nasal allergies (allergic rhinitis), including hayfever, pet allergies and dust mite allergies, in adults aged 18 years and over.
Beclometasone nasal spray can also be bought from general retail outlets such as supermarkets (as Beconase hayfever relief for adults nasal spray), but this more widely available product is only licensed specifically for the treatment of hayfever (seasonal allergic rhinitis).
