Your doctor is right about
the side effects of Reglan (metoclopramide). I was put on this and got muscle twitches in my face and legs after taking it for 4 months 4 times a day. I knew enough to stop the drug right away but it still took a couple of months for the "tardive diskinesia" to go away. In some people it never goes away. I can never take this drug again and had to make sure it wasn't given to me during my fundoplication surgery, because it could have triggered a severe form where you have awful grimacing permanently.
In the USA there is no medication available that does the same job as metoclopramide - making the pyloric valve
open so the stomach can empty.
