My Dr. Said he didn't like it. He and I just got finished battleing over the risk verses benifits of the med I'm on, and I got my wish. (to stay on it) So I didn't want to pursue any "issues". A search provided all negative feedback. Hepatic failure being one cause. Since I have had Hepititus C for 34 years, I did not like seeing that. It so happens I moved in Nov. and I'll be getting a new GI and EP . Not so sure I want to see either one of them. I have various side effects from my Med, or at least -we think. I do not want to get off the med and see if the issues clear up because I expect to be nonfunctioning- off the med. I need to work , I'm a single mom. I hoped low blood volume , or low BP might do it. Ah well , "I'll keep you posted".
