Capsaicin for Cannaboid Hyperemesis Syndrome

Capsaicin is the stuff in chili peppers that makes your mouth feel hot. But it also has some medical purposes. It’s a key ingredient in creams and patches that has been used for pain relief (e.g. joint, muscle, headaches).

From our recent hospital PNT meeting –information on using Capsaicin for Cannaboid Hyperemesis Syndrome (CHS).

What is cannabinoid hyperemesis syndrome (CHS)?

  • Clinical syndrome in which marijuana users develop nausea, cyclic vomiting, and abdominal pain that improves with a hot water bath or cannabis cessation
  • Often refractory to standard treatment for nausea/vomiting
  • No laboratory or diagnostic tests for CHS

Capsaicin Mechanism for CHS

  • Transient receptor potential vanilloid subtype 1 (TRPV1) receptor is expressed in the brain, along enteric and vagal nerves, and on cutaneous receptors in the skin
  • Chronic cannabis use results in inactivation of TRPV1 receptor leading to  nausea & emesis
  • Nociceptive heat, such as topical capsaicin, acts as a TRPV1 agonist restoring gastric motility
  • Activation of TRPV1 receptor results in potent anti-emetic effects
  • Capsaicin exposure results in subsequent desensitization of the sensory axons and inhibition of pain transmission initiation.

Topical Capsaicin

  • Product: Capsaicin cream 0.025% (Generic)
  • Dosing: Apply thin film to affected area not more than 3 to 4 times/day
  • Benefits:
    • Less adverse effects than unconventional antiemetics (e.g., haloperidol)
    • Cost-effective
  • Adverse effects: “burning sensation” on skin
  • Average wholesale price: $10 per 60 gram tube

Supporting literature

  • Graham J, et al.
    • Case series in which capsaicin was successfully used to treat CHS in two pediatric patients presenting to the emergency department (ED).
    • In a 16 yo & 20 yo, each with two ED visits, on the 2nd visit: due to history of cannabis use, CHS became working diagnosis, patients agreed to try capsaicin cream (0.025%, 1 mm-thick coating) applied to the abdomen. Thirty minutes after capsaicin application, patients pain decreased to a 3 out of 10 and her nausea resolved

My take: Capsaicin use for CHS is supported by case reports.

Getting In the Shower for Emetic Symptoms

A recent study (I Aziz et al. Clin Gastroenterol Hepatol 2019; 17: 878-86) examined the epidemiology and clinical characteristics of Rome IV functional nausea and vomiting disorders (FNVDs) in adults.  The study used internet cross-sectional health surveys from 5931 adults in 2015.

Key findings:

  • 2.2% of the population (n=131) fulfilled criteria for Rome IV FNVDs
  • Hot water bathing, which has been reported in cannaboid hyperemesis syndrome, was also noted  in patients with cyclic vomiting syndrome (CVS) in 44%.  “This behavior was independent of cannabis but augmented by its use.”

My take: FNVDs are common and hot water bathing is not pathognomonic for cannaboid hyperemesis syndrome.
