What Catacrom Eye Drops are and what they are used for

Catacrom Eye Drops are for the relief and treatment of allergic red, watery, itchy and puffy eyes
caused by hayfever, house mites, and other causes of allergy such as pet hairs. Eye allergy can happen
when sensitive eyes are exposed to these causes of allergy.
Catacrom Eye Drops is a medicine which affects cells called mast cells. It prevents them from
releasing chemical substances which cause symptoms such as the redness, watering, itching and
puffiness of allergic reactions.
These eye drops can be used by wearers of rigid or gas permeable contact lenses and can be used by
people who are sensitive to preservatives in other kinds of eye drops.
