We don't tend to use Norco (hydrocodone and acetaminophen) in the UK. Mostly Tramadol. And that 150mg dose my doctor suggested, I only ever used it as a one off. Once a day for the odd day (or night!) here and there. I doubt I used it more than half a dozen times altogether! And never for my second knee. You have to be very, very careful when using higher doses like that.
