Nasacort nasal spray contains the active ingredient triamcinolone, which is a type of medicine known as a corticosteroid (or steroid). Corticosteroids are hormones produced naturally by the adrenal glands that have many important functions, including control of inflammatory responses.
Triamcinolone is a synthetic corticosteroid and is adminstered by nasal spray to decrease inflammation in the nasal passages.
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, triamcinolone is absorbed into the cells of the nasal passages. It works by preventing these 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 it can take three to four days to have its full effect. It is therefore most effective to start using the nasal spray a few 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?Hayfever (seasonal allergic rhinitis).
Inflammation of the nasal lining that occurs thoughout the year due to allergies, eg to pets, dust mites (perennial allergic rhinitis).
This medicine is only intended for use in the nose and must not be taken by mouth.
It is important to shake the bottle gently before each use.
The spray should be primed before you use it for the first time. Do this by spraying it away from you five times until a fine mist is produced. If you don't use the spray for longer than two weeks then you will need to reprime it by spraying it away from you once before using it again.
Your nasal spray should be cleaned at least once a week, or more frequently if it doesn't work because it has become blocked. Follow the printed instructions supplied with the spray. Never try to unblock the spray or enlarge the tiny spray hole with a pin or other sharp object, because this will destroy the spray mechanism.
Any remaining spray must be discarded two months after you first open the bottle, because it may be contaminated with dirt or bacteria. Do not transfer any remaining suspension to another bottle. You may find it helpful to write the date of first opening on the bottle so you know when to throw it away. Dispose of carefully, preferably by returning it to a pharmacy.
If you think you have developed a nose or throat infection while using this medicine you should consult your doctor. You may need to stop using this medicine temporarily while the infection is treated.
When taken in high doses for long periods of time, corticosteroids have the potential to cause glaucoma, cataracts, thinning of the bones (osteoporosis), slowed growth in children and adolescents, and to decrease the functioning of the adrenal glands (glands that produce natural steroid hormones). These side effects on other areas of the body are called systemic side effects and are extremely unlikely to occur with this nasal spray, because the amount of triamcinolone absorbed into the bloodstream from the nose is very low. However, as a precaution, your doctor will prescribe the lowest effective dose needed to control your symptoms. You should not exceed this prescribed dose. Children and adolescents using this nasal spray for long periods of time should have their height monitored. Continuous use for longer than three months is not recommended in children under 12 years of age. For further information discuss this with your doctor.
