would be interested in what you took to improve renal function . I assume you went off Byetta in the hospital. How did you trace it back to the Byetta being the problem?
I went off Byetta in December due to new insurance not covering repeat Rx. I was worried about side effects and do not know whether the seven years I was on hte drug caused problems or not. There are American TV commercials for people to join class action suits for exenatide.
The weight loss only amounts to ten pounds for most people.
