I Have Been Taking Resolor For A Year With Success.

I have been taking resolor for a year with success. I was suffering from severe constipation which lead to SIBO and neurological symptoms, (Ataxia and dysarthria) after eating. I was also suffering from Severe weight loss. I ended up being fed VIA TPN for 9 months while my gut healed. I started the Resolor after the TPN was stopped. It helped with bowel movements. Recently my GI doctor stopped the Resolor. He felt it could be a dangerous drug since it is not available in the United States. I cannot find anything about it being dangerous. Since stopping the Resolor my symptoms are coming back. I have to use daily enemas. Please advise on the safety of resolor.
