Nutmeg and Clonazepam

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

Moderate

CNS DEPRESSANTS

Why this applies to Clonazepam

Clonazepam falls under CNS DEPRESSANTS — the group Nutmeg interacts with.

Theoretically, nutmeg might increase the risk of additive sedation when taken with CNS depressants.
Animal studies suggest that nutmeg extracts and several volatile oils in nutmeg, such as methyleugenol, isoeugenol, safrole, myristicin, trimyristin, 1,8-cineole, and geranyl acetate, have sedative effects. One animal study shows that petroleum ether extracts of nutmeg can potentiate the effects of pentobarbital or phenobarbital. However, evidence from other animal research suggests that the nutmeg constituent myristicin can actually reduce sleeping time in rats pretreated with phenobarbital.
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 simple version: clonazepam (Klonopin) already slows down activity in your brain to calm seizures and panic. Some lab and animal research hints that compounds in nutmeg may have their own mild sedative effect. Put the two together and the worry is extra drowsiness, things like feeling more sleepy, foggy, unsteady on your feet, or slowed down.

I want to keep this in perspective, though. This idea comes only from animal and test-tube studies, and the results are mixed (some even point the other way). A pinch of nutmeg in your eggnog or baking is very unlikely to cause trouble. Large 'medicinal' nutmeg doses are a different story and are unsafe on their own. If you're considering nutmeg supplements, just check with your pharmacist or doctor first.

From our pharmacist’s overview on the Clonazepam page

“Clonazepam (Klonopin) slows brain activity to control seizures and panic, and most of what interacts with it pushes in one of two directions: deepening that sedation or changing how much drug is in your blood. This is a list to approach carefully.”

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.

About Clonazepam

What Is Clonazepam Used For?

Brand names: Klonopin, Rivotril, Ceberclon

Clonazepam is approved to treat several types of seizures — including Lennox-Gastaut syndrome (a severe form of epilepsy), akinetic seizures (sudden loss of muscle tone), myoclonic seizures (sudden muscle jerks), and absence seizures (brief lapses of awareness) in patients who haven't responded to other medicines.

It is also approved for panic disorder, with or without agoraphobia (fear of situations that might cause panic). Panic disorder involves repeated, unexpected panic attacks along with ongoing worry about having more attacks.
