My Grandmother has taken Calan 60 mg for several years without any trouble. Within the last 6 weeks when she takes it, the pressure drops significantly (50 points or more) and she feels sick for at least 3 hours, with extreme fatigue, weakness and nausea, considerably affecting/limiting her daily activities. Could it be possible that she has developed "sick sinus syndrome"? I am a nurse & am very frustrated. She is due to see her physician next week, but have found that it is hard to get anyone to listen. Please send any suggestions you may have. Thank- you!!
