Have been on Crestor 10mg daily for over 6 years now. Cholestral reading was 7.6 before treatment then 4.2 thereafter.I am almost 71 years old now and for 2 months my pulse rate dropped to 40bpm. It became normal again ie 60- 80bpm. but is now irregular. I've had the Crestor dose dropped to 5mg now but no change. Anyone else had this experience?
