What This Study Found

Among 57 patients receiving capsaicin for suspected CHS, pain scores dropped from a median of 8 to 5.5, and nearly half required no additional symptomatic therapy after application.

Key Numbers

57 patients; pain score median 8 to 5.5; 98% received antiemetics; 47% received an opioid; 42% needed no further therapy after capsaicin; capsaicin applied at median 4 hours into visit

How They Did This

Retrospective chart review of 57 patients with suspected CHS who received capsaicin cream in an emergency department between July 2014 and October 2018.

Why This Research Matters

Cannabinoid hyperemesis syndrome is notoriously difficult to treat. Standard antiemetics often fail, and many patients receive opioids. A simple topical cream that provides relief could reduce reliance on more problematic medications.

The Bigger Picture

CHS has become increasingly common as cannabis use has risen. Finding effective non-opioid treatments for the severe abdominal pain it causes remains a clinical priority.

What This Study Doesn't Tell Us

Retrospective design without a control group. Capsaicin was typically given after antiemetics and opioids, making it hard to isolate its independent effect.

Questions This Raises

  • ?Would earlier capsaicin application produce better results?
  • ?Could capsaicin reduce the need for opioids if given as a first-line treatment for CHS?

Frequently Asked Questions

What is cannabinoid hyperemesis syndrome?

CHS is a condition in long-term cannabis users characterized by cyclical severe nausea, vomiting, and abdominal pain, often temporarily relieved by hot showers.

How does capsaicin cream help with CHS?

Applied topically to the abdomen, capsaicin cream reduced pain scores from a median of 8 to 5.5 in this study. The exact mechanism is unclear but may involve activating TRPV1 receptors, similar to the relief from hot showers.
