Hi: I've read that Bextra can cause eye problems. Have your friend look up the side effects on the internet. I've been taking Bextra for about 6 weeks. It upsets my stomach so I take it with antacid. That's the main side effect that I get. It does relieve my arthritis pain most of the time. Today, I took Aleve instead to see if that relieves my pain without causing side effects.
