After surgery in South Korea, I was prescribed round orange pills with MD M45 (MD on the top then a line horizontally across the pill then M45 on the bottom) imprinted on one side, and nothing on the other. The prescription was in Korean so I couldnt read it, but the doctor told me to take 1 pill 3 times a day for pain. I never asked what the medication was and Im not in contact with the hospital or doctor, but would like to understand what these pills are before I take them. Each pill came in an individual sleeve but that could just be the way they dispense medication in Korea. Any help would be appreciated
