atrial fibrillation
"After being shocked back into rhythm after a bout of afib, I was prescribed betapace 80mg twice a day. It has been two months and no afib although I feel irregular beats occasionally. I had several off and on days of urine burning as though I was on fire. Walked like I had been riding a horse for a few days straight. The pain was horrible. After trial and error I discovered that if I had a glass of coke after taking betapace the burning occurred in the evening. No cola no burning. Now I take betapace with milk and I feel much better. There should be a warning. Good luck!!"
