• Pergolide (Permax) is mainly used to treat Parkinson’s disease. It will no longer be sold, because it may damage your heart valves. But stopping pergolide too quickly can be dangerous, so if you are taking this medicine, don’t try to stop on your own. It’s important to talk to your doctor first. There are other medicines that work like pergolide and can treat Parkinson’s disease.
  
  
• Tegaserod (Zelnorm) is used to treat chronic constipation and irritable bowel syndrome. If you are taking this medicine, you may have a higher chance of heart attack, stroke, and chest pain.
