Cowhage and Etomidate

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANESTHESIA

Why this applies to Etomidate

Etomidate falls under ANESTHESIA — the group Cowhage interacts with.

Theoretically, concomitant use of cowhage and anesthesia might increase the risk of arrhythmias.
Cowhage contains levodopa. Use of levodopa with cyclopropane or halogenated hydrocarbon anesthesia has led to arrhythmias. Other anesthetics have not been implicated. Use other anesthetics in patients taking cowhage or tell patients to stop taking cowhage at least 2 weeks before surgery.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Etomidate is a fast-acting medication used to put you to sleep at the start of anesthesia, usually given in the hospital or operating room. Cowhage is a natural source of levodopa, and there is a theoretical concern that mixing levodopa with certain anesthesia could nudge the heart toward an irregular rhythm (an arrhythmia).

Here is the honest picture: this worry comes mainly from older anesthetics like cyclopropane and some halogenated gases, not etomidate itself. Etomidate has not been linked to this problem, and the evidence overall is weak and anecdotal. Still, the safe habit is simple. If you take cowhage and have surgery coming up, tell your anesthesiologist and pharmacist ahead of time. They may ask you to pause cowhage for about two weeks before your procedure.

About Cowhage

What is Cowhage?

  • Parkinson's disease symptoms
  • Male fertility and libido
  • Mood and stress support
  • Traditional aphrodisiac
  • General energy and vitality

Cowhage (Mucuna pruriens) is a tropical legume best known as a natural source of L-dopa, the compound the body turns into dopamine. It is most studied for Parkinson's disease symptoms and male fertility, but evidence is still limited and the L-dopa content makes it potentially powerful and risky—talk to your doctor or pharmacist before using it.

About Etomidate

What Is Etomidate Used For?

Brand name: Amidate

Etomidate — available as Amidate and under the generic name Etomidate — is given by intravenous (IV) injection to induce general anesthesia before surgery or other procedures. It brings on unconsciousness rapidly, usually within about one minute.

Amidate and etomidate injection products are also used to supplement weaker anesthetic agents, such as nitrous oxide in oxygen, during short operative procedures — for example, dilation and curettage (D&C) or cervical conization. This supplemental use is supported only for adult patients in short procedures; it is not recommended for longer procedures or for pediatric patients.
