I have been taking 300 mg of Wellbutrin and 30 mg of Vyvanse for about a year now and recently my heart has been racing (100-110 beats per minute after sitting on the couch for an hour) and I have been having minor chest pains. Also, I have been feeling "out of it" sometimes during the day, and experience dizziness, confusion etc. on occasion. I was wondering if this could be related to my medications and if there is need to be concerned about my heart rate. I am on the Nuvaring and my mother has mitral valve prolapse if that matters at all. Also when I was about 8 I went to the ER/Cardiologist because my heart was racing for hours but no cause was found and I haven't experienced any problems since until now.
