A tardive-dyskinesia patient usually experiences facial symptoms like uncontrolled grimaces or involuntary eye movements. Arms, legs, hips, and torso may also twitch or move uncontrollably. Severe cases of the condition can be debilitating, but even mild ones are embarrassing and reduce quality-of-life. There is no known cure for tardive-dyskinesia, so sufferers must adapt.
Reglan can also produce milder side effects, including dizziness, decreased energy, diarrhea, nausea, headaches, and vomiting. But it is tardive dyskinesia that has been the basis for many lawsuits against Pfizer.
