Guest guest Posted August 14, 2005 Report Share Posted August 14, 2005 Yepper, so you saying the Revia I just got that Barr makes is the very same as the generic but has the word Revia on the pill? That should be illegal b/c they are both the same pill and they charge more for the word Revia on it! So, is what we get from medsmex going to be different in the future and made by Barr Labs? Barr Lab told me they do not make out of the country, just in US. So who is making the medsmex Revia and will the box soon not say Bristol Myers? I had a friend give me his credit card to get some more from Mexico b/c I'm so paranoid that the Barr Lab Revia is the same as the generic. Can't beleive I had to pay $35 copay for the same stuff as the generic $10. So is everyone here that has REVIA not from medsmex got the Revia made by Barr Lab then? I will mix a batch to see but just have to know I have the Revia from Mexico on hand. I can tell you the generic did not work for me which I find so bizzare if it has naltrexone in it. I'm still doing fine back on the medsmex Revia and went out dancing til 1am last night. If I check around at other pharmacies, does that mean all the Revia is made from Barr Labs in US now?
