Crolom (Ophthalmic)

Cromolyn ophthalmic solution is used in the eye to treat some eye problems caused by allergies. It works by affecting certain cells, known as mast cells, to stop them from releasing substances that trigger the allergic reaction.

Cromolyn is available only with your doctor's prescription.

If your symptoms do not get better or if your condition gets worse, talk to your doctor.
