Metoclopramide
Warning
This medication may cause a serious movement disorder called tardive dyskinesia. In some cases, this condition may be permanent. The risk of tardive dyskinesia is increased with the longer use of the medication and the more medication that you take. The risk is also increased in older adults (especially women) and in people with diabetes. Metoclopramide comes in different forms (such as tablets, solution, injection). Do not use metoclopramide products for longer than 12 weeks. Talk to your doctor about the risks and benefits of this medication.
Tell your doctor right away if you develop any unusual uncontrolled movements (especially of the face, mouth, tongue, arms or legs). There is no treatment for tardive dyskinesia, but in some cases the symptoms may lessen or stop once metoclopramide is stopped.
