I was diagnosed with silent reflux & gastroparesis. i was prescribed reglan (metoclopramide) . having heart palps and stopped reglan (metoclopramide). can 500 mg cause this too?

Check dosage: Side effects of reglan (metoclopramide) can be quite serious, but heart palpitations is not one of them. However, I am concerned about the dosage you are saying. Is that over 24 hr? 10mg every four hours is the higher end of normal, and Reglan (metoclopramide) is not a medicine you want to take for long periods of time. Please see the Rx'ing MD regarding this, and to go over your other medications and symptoms.
