Recommended pain treatments for osteoarthritis (OA) and chronic low back pain (CLBP) are suboptimal, and limited information is available regarding patterns of pharmacotherapy among patients with these conditions. ⋯ This study demonstrates that therapy switching and discontinuation of select pain medications were common among OA and CLBP patients in the U.K. and may result from inadequate pain relief or undesirable side effects.
