I've taken prinzide for about seven months and have suffered dizziness, severe heartburn/acid indigestion, confusion, irregular heartbeat, numbness/tingling in my extremities, a general feeling of malaise, and tachycardia. The dizziness and heartburn were irritating; the tachycardia was downright scary. I would wake up from a dead sleep and my blood pressure would be around 117/60 and my heart rate would be 105 bpm! I've been off Prinzide for five days and my heart rate is in the 70-80 bpm range -- still not great, but much better.
