Lecrolyn sine is used to treat eye symptoms due to allergy. It works by stopping the release of the natural substances like histamine in your eyes that can lead to an allergic reaction. Signs of an allergic reaction include itchy, watery, red or inflamed eyes and puffy eyelids. Usually both eyes are affected. These symptoms occur usually in spring or summer when pollen from grasses or trees comes into contact with the eyes of people who are sensitive to them.
This medicine is used for treatment of adults and children over 6 years old.

Active Ingredients

Lecrolyn Eye Drops contain Sodium Cromoglycate as an active ingredient. It works by inhibiting the release of the elements causing allergic reactions in a mucous membrane of eyes. This has been used since the 1970s for the treatment of allergic conjunctivitis.
Sodium cromoglicate works by preventing the reaction that causes the eyes to become inflamed and uncomfortable. It doesn’t stop the reaction once it has started. So it usually takes a few days before the effect of sodium cromoglicate becomes noticeable and during this time, other medicines, such as anti-histamines, will also need to be used, to treat the symptoms of AC. To stop the reaction happening again, the sodium cromoglicate eye drops need to keep being instilled into the eyes after the reaction is over. Lecrolyn sine eye drops, does not contain any preservative, so can be used together with contact lenses.
