My mother has been on metoclopramide for several months, maybe as much as a year, up to 4 times daily every day. She developed severe tremors, shaking so badly that she could no longer sort her own meds or use her iPhone. So in taking over the sorting of her meds I've been researching the side effects of each. Seems like this one is most likely to be the culprit. Are there any side effects from suddenly stopping this med or should we step down as with some other meds?
