Like "I take three pills a day metformin 500mg 1 morning 1 night then for blood pressure I take amlodipine/benazepril & atenolol both at the same time around noon. I asked my pcp if I should put some time inbetween the two pills and he said to take them at the same would not hurt. I use to take the morning metf. with the 2 blood plesure pills at the same time. Hope it helps better the my last reply???"
