Nutmeg and Edrophonium

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

Moderate

CHOLINERGIC DRUGS

Why this applies to Edrophonium

Edrophonium falls under CHOLINERGIC DRUGS — the group Nutmeg interacts with.

Theoretically, concomitant use of nutmeg with other cholinergic drugs might have additive effects and increase the risk of cholinergic side effects.
Animal research suggests that nutmeg extract can inhibit acetylcholinesterase and might increase acetylcholine levels.
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

Here's the gist: Edrophonium works by blocking acetylcholinesterase, the enzyme that breaks down acetylcholine. That lets acetylcholine build up so nerves and muscles signal more strongly. Interestingly, lab and animal studies hint that nutmeg may block that same enzyme. So in theory, pairing the two could stack their effects and push acetylcholine higher than intended.

If that happened, you might see more cholinergic side effects: watery eyes, drooling, sweating, belly cramps, nausea, a slow heartbeat, or muscle twitching. I want to be honest though, this is purely theoretical and based on animal research, not real-world cases. Normal cooking amounts of nutmeg are very unlikely to matter. Since edrophonium is given in a clinical setting, just mention any nutmeg supplements to your doctor or pharmacist first.

  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

From our pharmacist’s overview on the Edrophonium page

“Edrophonium (Tensilon, Enlon) is a short-acting medicine given in clinics, usually to test for myasthenia gravis or reverse muscle relaxants, and none of the 22 supplements on this page rise above moderate concern. Nearly all of them act the same way edrophonium does, blocking the enzyme that breaks down acetylcholine, so pairing them…”

About Nutmeg

What is Nutmeg?

Nutmeg
  • Digestive upset
  • Diarrhea
  • Sleep and relaxation
  • Pain and inflammation
  • Flavoring spice

Nutmeg is a popular cooking spice that has long been used in traditional medicine for digestion and other complaints, but there is little solid human research to support its medicinal use. In normal cooking amounts it is generally safe, but larger "medicinal" doses can cause serious poisoning, so it should never be taken in high amounts.
