Hi, my wife had a boil under her arm and when she went on a regular appointment to her gynocologist he said that she was tender and she may have an infection. He prescribed her Bactim DS 800, told her to take two at a time twice a day. So she went to a family doctor and was told that the boil was infected and had it lanced, they gave her the same medicine but one at a time twice a day. Ever since she has been taking them two at a time she has been nauziated and can't stand for long at all. Do you think she is suppose to be taking one at a time? What do you think is wrong?
