Mace and Acetaminophen, Dichloralantipyrine, Isometheptene

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Mace interacts with whole categories of medication. Acetaminophen, Dichloralantipyrine, Isometheptene falls into 2 of those categories, so it can interact with Mace in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Acetaminophen, Dichloralantipyrine, Isometheptene

Acetaminophen, Dichloralantipyrine, Isometheptene falls under CNS DEPRESSANTS — the group Mace interacts with.

Several volatile oils in mace, such as methyleugenol, isoeugenol, safrole, myristicin, 1,8-cineole, and geranyl acetate, seem to have sedative effects. Evidence from animal research suggests that methyleugenol can induce anesthesia for a similar duration as pentobarbital. Due to the sedative effects of certain mace constituents, taking medicinal amounts of mace in combination with other CNS depressants may have additive effects. However, evidence from other animal research suggests that myristicin can reduce sleeping time in rats pretreated with phenobarbital. Until more is known, use medicinal amounts of mace cautiously in combination with CNS depressants. Some CNS depressants include clonazepam (Klonopin), lorazepam (Ativan), phenobarbital (Donnatal), zolpidem (Ambien), and others.
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 explains PharmD, Clinical Pharmacist

This combination headache product already has a built-in sedating ingredient. The dichloralphenazone part is a mild sedative, and isometheptene plus the acetaminophen (Tylenol) round it out. So drowsiness and lightheadedness are effects you may already notice when you take it for a migraine.

Here is where mace comes in. Some of the aromatic oils in mace (like myristicin and methyleugenol) appear to have a calming, sleep-promoting effect in lab and animal studies. In theory, larger medicinal doses of mace could stack on top of the sedation from this medication, leaving you more drowsy, foggy, or unsteady. To be clear, this is a theoretical concern based on pharmacology, not strong human proof, and the sprinkle of mace you use in cooking is very unlikely to matter. Concentrated mace supplements are the real question. Please check with your pharmacist or doctor before combining them.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

2 of 2

Acetaminophen, Dichloralantipyrine, Isometheptene also falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES.

Animal research suggests that intraperitoneal injections of myristicin, a constituent of mace, can induce cytochrome P450 1A2 (CYP1A2) enzyme system. Theoretically, concomitant use of mace with drugs metabolized by CYP1A2 may increase the clearance of these drugs and reduce their effects. Some substrates of CYP1A2 include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), theophylline, zileuton (Zyflo), zolmitriptan (Zomig), and others.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

This combination pill, sold as Midrin or Migratine, mixes acetaminophen (a pain reliever), isometheptene (which narrows blood vessels), and a mild sedative for migraine relief. The idea here is that a compound in mace called myristicin might gently speed up a liver enzyme (CYP1A2) that helps process some medicines. In theory, that could clear parts of this medication a little faster and make your migraine relief feel weaker.

Honestly, though, this is very theoretical. It comes only from animal injection studies, not real people, and the main pain piece, acetaminophen, isn't mainly handled by CYP1A2. Sprinkling mace as a spice almost certainly won't matter. If you're thinking about concentrated mace supplements, run it by your pharmacist or doctor first.

About Mace

What is Mace?

  • Digestive upset and gas
  • Flavoring and culinary spice
  • Nausea
  • Appetite stimulation
  • Traditional pain or muscle relief

Mace is the lacy red covering of the nutmeg seed and comes from the same tree as nutmeg. It is mostly used as a cooking spice and in traditional medicine for digestion, but there is little solid human research to support its health uses. In normal food amounts it is generally safe, but large doses can be toxic, so use it as a spice and check with your pharmacist before taking concentrated supplements.
