Celecoxib
"I have been on Celebrex off and on, over the last 10 years or more. I take it mainly for lower back pain. I understand it increases your chance of heart attack and stroke, so I take it only when I need it. It is hard on your stomach, so take it after a meal. But it really helps ease my lower back pain. I don't understand why the price for my prescription was $300.   this month. It's never been that high! That's why I'm here, looking to see if there is an explanation. The chemist told me to call my insurance company, as he didn't know. Its a good medicine but its so expensive now I'll probably have to phase it out."
