Use of Capsaicin Cream in Cannabinoid Hyperemesis Syndrome in Patients Presenting to the Emergency Department.

This is the largest retrospective study describing capsaicin cream use in suspected CHS patients with a focus on abdominal pain relief. Capsaicin treatment was associated with a modest pain score reduction. Application of these findings may help providers in identifying more effective therapies to provide symptomatic relief for CHS patients.
