I Have A Friend Who Has Every Odd Rxn To

i have a friend who has every odd rxn to meds that u can. I am a retired rph. several years ago she was given different generic forms for verapamil with horrible results. one worked perfect the other not at all. one was a tab and the other a capsule. after that i always made sure she got the same generic. now due to ventricular tachicardia the cardiologist has increased the strength. The first one a tablet worked great, the refill was a capsule and she is about ready to have a heart attack. Her rph says the don't have a tablet and she had to have gotten a capsule. Don't they still make a generic for calan 320 in a white tab form instead of green capsules generic for verelan.thanks
