I took it post surgery, it is really just like taking 800MG ibuprofen every 6 hours. You don't want to take it long term because it can give you an ulcer or any of the other painful stomach and health issues that come with NSAIDS.

However, that said it was great for pain while i was taking it. I believe manufacturer says no more than 5 days, but my surgeon had me continue for two weeks. Nuerologist told me to quit after that because the long term safety of the narcotics is actually much higher. (no risk of heart issues or stomach ulcers)
