I am a arthritis patient and have been getting pain medication for over three years. I first began getting oxycodone 30 mg and they were little blue round pills with a V on one side and 48|12 on the other side. Every six months or so my pharmacy would give me a different pill. From V|48 12 to M 30's to A-214 to A225's. Now I am getting R P 30's that for some reason give me diarrhea and depending on how many I take. can also give me stomach pains. I just wish I could get the V| 48-12's like I was getting at the start. Can you offer me any advice?
