Timara, this is Nella Jack's mom. iIt's been a while dear. hHow are you? The pills I suggested for your father; only give him two daily - one in the morning,and one in the evening with a meal. It says give him 1 x three times, but two is all he will need. As for taking Cystex, he may, or may not experience diarrhoea the first time he takes it, so you will have to monitor that, other than that, he will be pain free.
