Patch and Steroids Equally Effective for Shoulder Pain

For patients with shoulder impingement syndrome, a twice-daily heated lidocaine tetracaine patch (Synera, ZARS Pharma) reduces pain to the same extent as a single steroid injection, a new study shows.

"Based on this small study, it appears that in the short term, both the lidocaine tetracaine patch and injections are helpful in reducing pain and restoring more normal range of motion for shoulder impingement syndrome," said lead investigator Richard Radnovich, DO, from the Injury Care Medical Center in Boise, Idaho.
