I have been taking Cardizem CD 120mg for 4-5 years for frequent PVC s. I do not have angina, no history of MI, no structural abnormalities, normal Echo, normal EKG other than the PVC s. I do have HTN that is well controlled with Fosinopril 20mg qd. I would like to try to discontinue the Cardizem. Is this safe to do?
Hello! Thank you for asking on Chat Doctor! Regarding this issue, I recommend you to consult with your cardiologist (who prescribed you Cardie), as he knows exactly your prior rhythm profile before starting the Chat Doctor.  In judging about an anti-arrhythmic treatment, we have to investigate its effectiveness. So, I would recommend you to perform an ambulatory 24 to 48 hours ECG monitoring, and discuss with your doctor on the results. If you decide together to stop Cardie, then a periodic follow-up, would be necessary to control for any possible arrhythmia events. Hope to have been helpful to you. Greetings!
