My mother was prescribed Reglan following surgery for colon cancer. She had delayed gastric emptying and also had pre-existing hiatal hernia and GERD. She was kept on the Reglan for 3 years, now has Tardive Dyskinesia. It is pitiful to observe. She has constant involuntary head jerking (side to side) and involuntary mouth movements that look as if she is chewing. We only found out recently that the problem is Tardive Dyskinesia, when she was referred to a neurologist with suspected Parkinson's Disease because of "stiffening" of the extremities and tremors. Parkinson's was ruled out, instead we were told the muscular stiffness, along with the involuntary movement disorder, is due to the side effects of Reglan. It is a dangerous drug.
