I went to my pharmacy 2 weeks ago & they asked me if I wanted generic or brand. I told them brand and that I didn't know there was a generic. They filled the prescription with brand name ones and they were the OP ones. Today I went back to pharmacy and inquired about the generic and asked what they looked like and who made them. The pharmacist said that she thought the same company (Purdue) made them. I asked if I could see one and was surprised that they had the OC on them and looked exactly like the old brand name ones. I asked if I could have them and that's what I got. I did think that there was alittle difference in the OP ones, but as far as I can tell these new "generic" are exactly like the old brand name ones. I'm not sure if Purdue is making the new ones that say OC because the manufacturer on the prescription bottle and on the paper work the pharmacy gives says the manufacturer is Ethex. Hopefully these stay available.
