Depends. If your glaucoma is an open angle type of glaucoma, then you can be free to use any medication. However if you have narrow angles, this may be contraindicated. It is best to ask your doctor which kind you have, and if it is narrow, ask if it is okay for you. Sometimes when narrow angle patients have been adequately treated, they can be able to use these meds. Hope this helps!
Anti-allergic drugs. Most with glaucoma have a problem with fluid flow in the eye termed open angle which is by far the most common. An uncommon type is angle closure which theoretically can be affected by some anti-allergic products. If you are younger than age 50, don't worry. In any event a problem with glaucoma caused by anti-allergic products is rare even though the package cautions you about glaucoma.
