3 months ago I was put on oxycodone ( Rhodes) It worked fine….a little different than 10 yrs ago but it was ok. Then the shortage came. I had to go on vicodin which didn't work very well. I had to take double dose. NOW this month, the only oxycodone available was KVK! OMG! What terrible brand this is. It's like taking a sugar pill with severe side effects RE: severe headaches…no help for pain at all! How can the drug companies get away with this? Where can I send one of these to be tested to see what's in it?
