"Diltiazem for High Blood Pressure: Atrial Fibrillation: Atrial Flutter
 
I took Diltiazem before surgery and then continued it after for high blood pressure.  It worked just fine for a while although the 12 hr only lasted for 4- 5 hours in my case. Then I started getting toothaches and really bad gingivitis. I did have gingivitis already. I also started feeling lousy and only by coincidence did I stop taking the Diltiazem. Two day later my toothaches were gone and my gums stated clearing up. I still thought it was a coincidence. I restarted Diltiazem again and the same thing happened again."
