arrhythmia
"Overall, Norpace has been a lifesaver with few side effects that are noticeable. I have been taking Norpace for 16 yrs and have had to increase from taking two per day, three per day and they are considering 4.  But, there have been no side effects at all that I can attribute to Norpace on its own, other that I cannot take it with Levaquin, an antibiotic, at the same time.  No idea why, was given strong advise from the pharmacist.  Appreciated his advice."
