My mother has been taking Calcicbloc 10mg for years, and recently, at age 59, my heart was pumping so hard that I could almost hear it, my heartbeat raced-up with my blood pressure measured at 190/110. The doctors at ER gave me Calcibloc OD 30mg and I was ok in an hour. When I looked up this drug in the web, the info was very scant and sketchy. Why is that so?
