Rynacrom nasal spray contains the active ingredient sodium cromoglicate, which is a type of medicine used to prevent the symptoms of allergies. Sodium cromoglicate nasal spray is used to prevent the symptoms of nasal allergies such as hay fever.
Sodium cromoglicate works by reducing allergic responses. It is not fully understood how it does this, but it is thought to work by 'stabilising' immune cells called mast cells.
Mast cells are an important part of the immune system. They become sensitised when they are exposed to foreign particles or allergens, for example pollen or dust mites. When this happens, the mast cells release substances that include histamine, and these cause inflammation as part of the body's immune response to fight the foreign substance. Inflammation of the nasal lining causes the typical symptoms of a nasal allergy - blocked or runny nose, itching and sneezing.
By stabilising the mast cells, sodium cromoglicate is thought to prevent the substances that cause the inflammation, eg histamine, from being released when the cells encounter an allergen. This helps prevent the allergic response and reduce the symptoms of the allergy.
Rynacrom nasal spray is used to prevent a blocked or runny nose, itching and sneezing caused by nasal allergies (allergic rhinitis) such as hay fever. It works best if you start using it a couple of weeks before you expect to be exposed to the allergen. You should use it regularly as long as you are around the allergen, even when you don't have symptoms.
This nasal spray is suitable for all age groups.
