I take blood pressure medication. My PCP told me some time ago that Advil and Alive both raise your blood pressure. I am sure this would raise the risk for strokes and heart attacks. I have two bad knees and my Ortho told me a year ago he quit prescribing Celbrex and Viox. He told me there were serious side effects.Tylenol is worthless. I get T-3"s from my Orthro, and he changes to Davocet to stop the tolerance. But I do not get much.I refuse to pay Op prices so I live with alot of pain. Some country we live in!
