Calan SR Drug and Medication User Reviews

I started taking this medication for about a month,after loosing my hair while on Topamax, and I had about four headaches that just wouldn't go away. I had to just wait them out. Then at the end of the month, I started getting really dizzy after I got out of the shower to the point that I would pass out. This happened three times in a row, and my neuro immediately took me off of Calan SR.


I was placed on calan originally to help with my Raynauld's condition. I have since developed high blood pressure and high colesteral otherwise I am an active 64 year old. Could there be an underlying condition I am not aware of?


I've been taking 120 mg/day for the past 6 months for the prevention of severe headaches. I have had only 2 headaches since starting this med.


My boyfriends suffers from cluster headaches. Not only does this medicone not help, but it slows his heart rate and makes thins increasingly more difficult. I do not reccomend this drug for cluster headaches.


My 12 yr. old son has suffered from Migraine's for awhile. After trying several different medications this one finally did the job :) He's been taking it for almost 2 months and no migraine's.


I continue to have periods of increase heart rates at times and depression. Low blood sugar is also a problem. I use to have migraine headaches. But after I started taking Calan SR Oral. I stop having them. That was a big plus for me. The headaches were debilitating.
