Fresh are undoubtedly more effective, though, in my experience. None of that blasted corn syrup, either (g!).
Yah, I know ibuprofen doesn't help everyone. The stuff your doc gave you is killer, though (can't recall the name); supposed to work well for everybody. My **former** doc lectured me about it one day (that was his style -- bloody thought he was G-d, everything was a lecture).
I think the drug most commonly prescribed to stop gout attacks these days is indomethicin. It's called "super aspirin." Ibuprofen is often prescribed for joint inflammation too but it's bad for the liver.
