What to do if i have glaucoma. what medications should i avoid using?

Depends: If you have glaucoma, you will need your eye pressure controlled, either by eye drops, laser, or surgery. And you will need regular follow-ups, to ensure that your pressure is indeed controlled and that your glaucoma is stable. There is a specific type of glaucoma called Narrow Angle Glaucoma that may require certain medications to be avoided. See your eye MD for your specific type of glaucoma.

Depends: Talk to your doctor about what type of glaucoma you have. Most over the counter medications with a warning label to consult with your physician before using are specifically targeting Narrow angle forms of glaucoma (primary, secondary). If you are not affected with narrow angle glaucoma, then these medications may be taken as labeled and/or by the advice of your health care practitioner.
