Nasobec aqueous nasal spray contains the active ingredient beclometasone dipropionate, 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. 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 hay fever 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.
Nasal inflammation giving hay fever-type symptoms can also sometimes occur without allergy or infection. This is called vasomotor rhinitis and can also be treated with beclometasone nasal spray.
The nasal spray will not relieve the symptoms of nasal inflammation immediately, and can take two to three 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 while you are still being exposed to the allergen to keep the nasal inflammation under control.
Beclometasone nasal spray is suitable for adults and children aged six years and over when prescribed by a doctor.
Beclometasone nasal sprays can also be bought over-the-counter from pharmacies, but only for the prevention and treatment of nasal allergies (allergic rhinitis), including hay fever and pet allergies, in adults aged 18 years and over. They can also be bought from general retail outlets such as supermarkets, but these more widely available products are only licensed specifically for the treatment of hay fever (seasonal allergic rhinitis) in adults aged 18 years and over. See the factsheets linked at the end of this page for more information about these products.
This medicine should not be used if you are allergic to any of its ingredients. Please inform your doctor or pharmacist if you have previously experienced such an allergy.

Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.
Medicines and their possible side effects can affect individual people in different ways. The following are some of the side effects that are known to be associated with this medicine. Just because a side effect is stated here does not mean that all people using this medicine will experience that or any side effect.
Side effects similar to those associated with corticosteroids taken by mouth may occur if this medicine is absorbed into the bloodstream. The risk of this when using a steroid nasal spray is very low, but may be more likely if the medicine is used at high doses for prolonged periods of time. See the warning section above or talk to your doctor or pharmacist for more details.
The side effects listed above may not include all of the side effects reported by the medicine's manufacturer.
For more information about any other possible risks associated with this medicine, please read the information provided with the medicine or consult your doctor or pharmacist.
Beclometasone is not known to affect other medicines when administered into the nose as a nasal spray.
However, if you are taking any other medicines, including those bought without a prescription and herbal medicines, you should tell your doctor or pharmacist before you start treatment with this medicine. This is particularly important if you are or have recently been using any other medicines that contain corticosteroids, for example tablets, injections, eye or nose drops, creams, asthma inhalers, or other similar nasal sprays. This is because there may be an increased chance of adverse effects if you are using more than one type of steroid medication and your doctor may want to monitor you more closely.
Beclometasone nasal spray is also available from pharmacies and on prescription without a brand name, ie as the generic medicine.
