Overview
Sodium Cromoglicate 2% Eye Drops contain sodium cromoglicate, an anti-allergy medicine that works by stabilising mast cells in the eye. Mast cells release histamine and other inflammatory substances during an allergic reaction, leading to itching, redness, and watering. By preventing this release, sodium cromoglicate helps control allergy symptoms before they fully develop.
These eye drops are commonly used to treat allergic conjunctivitis, including symptoms triggered by pollen (hay fever), dust mites, pet dander, and other environmental allergens. Unlike antihistamine eye drops, sodium cromoglicate works best when used regularly and may take a few days to reach full effectiveness.
Sodium Cromoglicate Eye Drops are gentle, non-steroidal, and suitable for repeated daily use throughout allergy season. They do not cause drowsiness and can be used alongside oral antihistamines if needed.
