Yes: If you have been told that you have narrow angle, then you may want to be cautious and check with your eyecare specialist.
Dr. Constance Okeke

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!

Yes: There is no problem with Allegra (fexofenadine) or other antihistamines when you have glaucoma.
Dr. William Dieck
Ophthalmology 38 years experience
Probably OK: Allegra (fexofenadine) is in the class of drugs known and antihistamines. People with an specific anatomical shape in their eye may be at risk for angle closure glaucoma. Antihistamines have been known to incite an angle closure glaucoma attack in some people with this risk. Open angle glaucoma patients do not need to worry. Your ophthalmologist should be able to tell you if you are at risk.
