"was prescribed 2 mg tablets to be taken 1 or 2 pills every 3 or 4 hours after my complicated rotator cuff surgery which involved reattaching three completely torn through tendons. the pills were completely ineffective. they did nothing for my pain. i quit taking them after the first day.  i could not tell that i had taken anything. the circulating ice water machine they send you home from surgery with and regular advil provided much better relief."
