How does this medication work? What will it do for me?
Sodium cromoglycate belongs to a group of medications called mast-cell stabilizers. It is used to prevent or treat the symptoms of seasonal allergic rhinitis such as itching, sneezing, and runny or stuffy nose.
This medication works by preventing the release of natural chemicals from cells in the body (mast cells) involved in an allergic reaction. This medication may take up to one week before you begin to notice symptom relief.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are using this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.
How should I use this medication?
This medication is more effective when used before your symptoms begin and at the start of the allergy season. If possible, start this medication 1 week before your usual seasonal allergy symptoms occur.
When used for preventing allergic symptoms, the usual recommended starting dose for adults and children over 5 years old is 1 spray into each nostril 6 times daily. When your symptoms are under control, the dose should be decreased to 1 spray into each nostril 2 to 3 times per day (every 8 to 12 hours). If you do not get symptom relief after 7 days of starting treatment, contact your doctor.
Continue treatment throughout the allergy season, even if you are free of symptoms, to help maintain relief.
To use the nose spray, remove the dust cap from the pump and remove the security clip from around the neck of the pump. To prime the pump, press downward on the shoulders of the applicator, using your forefinger and middle finger while supporting the base of the bottle with your thumb. Press down and release the pump until a fine spray appears. Holding the bottle upright, insert the tip into your nostril and press the bottle fully upwards with your thumb, then release. Repeat the procedure for your other nostril. Wipe the nosepiece after each use to prevent contamination. Replace the dust case and security clip after using.
