这个药片每天三次每次两粒英语怎么说？

如果是书写在药瓶上

Dosage: Two tablets to be taken three times daily.
剂量: 每天三次每次两粒

比如医生跟病人说：
Dr. Chen said "You must take two tablets each time, and three times daily."

药学名词用 tablets， 一般日常口语可以用 pills。

take these pills 2 pills a time, 3 times a day

take the pill 2 tables once, three times per day.
