arrhythmia
"I have been on this medication for 22 years. I have a weird vagatone form of a-fib.I was on Procanimide for 10 years, but developed chemically induced lupus. After 4 hospitalizations and 3 cardio conversions, Norpace CR was the only drug that worked comfortably for me. Unfortunately it is currently out of production and not scheduled to be available again until March, 2018 ( today is 9/1/17. This has happened several times in recent years, there is no generic CR. MSs don't like it as it is an old drug and is contraindicated with 400 other medicines under 1200 brand names, but it works for me when most of the new drugs don't. I am 65 now and my EP wants to do a pacemaker which I intend to postpone as long as possible."
