I was diagnosed with parkinson's disease on January 2011. I have been on azilect since March. I have a dreadful toothache and am in pain. I tried getting off of it and started to have withdrawal symptoms e.g., heart palpatations, anxiety, shaky, nervous etc. Question: Can one stop taking azilect without being 'monitored'? How long before withdrawal symptoms begin and end? I also need to undergo a colonoscopy and can't be on it. Are there any recommendations for easing this process?
