Hi Tina: As far as my opinion on Darvon, I think it's worthless. It certainly is NOT stronger than Hydrocodone. I may be mistaken, but I think at one point several years ago (late 80's maybe), there was talk of making Darvon a nonprescription med. I'm not sure what happened with that, but I wouldn't even bother to fill the script if a doctor gave me one for Darvon or Darvoset.
