My psychiatrist prescribed me Vyvanse, but with a quick look on the web you find information about the risks of taking this drug if you have heart problems. I have a benign heart arrhythmia and I wanted to discuss that matter with my doctor, but she responded that this is not urgent and we will only discuss this at our next appointment. So frustrating. I would have to wait 10 days before starting this medication, which seems to be really helpful to everyone here. Has anyone here heard anything from the doctor about heart problems?
