Description

Sodium Cromoglicate are eye drops used to treat allergic conjunctivitis (hay fever) by reducing the redness, itch, watering and irritation of the eyes associated with the condition. Sodium Cromoglicate works by stabilising the mast cells that release histamine.
 

Directions

For best results, these eye drops should be used four times a day.

Ingredients

The main ingredient is Sodium Cromoglicate.

Warnings

Sodium Cromoglicate is generally well tolerated, but mild side effects can occur.
Common effects include temporary stinging or burning after use, mild nasal irritation, or blurred vision with eye drops.
Some people may experience headaches, sneezing, cough, or an unpleasant taste.
These effects are usually mild and short-lived.
Seek medical attention if signs of an allergic reaction, such as swelling or difficulty breathing, occur.
