Caraway and Glutethimide

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

Moderate

CNS DEPRESSANTS

Why this applies to Glutethimide

Glutethimide falls under CNS DEPRESSANTS — the group Caraway interacts with.

Theoretically, caraway might increase the effects and adverse effects of CNS depressants.
Animal research suggests that (S)-(+)-carvone, a major constituent of caraway seed extract, has sedative effects.
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

Glutethimide is an older sedative sleeping pill that already slows down your brain and nervous system, leaving you drowsy and relaxed. The concern here is that caraway, mainly its oils like carvone, may have a mild calming effect of its own. Stacked on top of Glutethimide, that could in theory deepen the sleepiness, leaving you groggier, more unsteady on your feet, or slower to think clearly.

I want to be honest about the strength of this: it's theoretical, based on animal studies, not real cases in people. A sprinkle of caraway in your bread or stew almost certainly won't matter. Concentrated caraway oil or supplements are where I'd be more cautious. Please run any caraway supplement past your pharmacist or doctor first.

About Caraway

What is Caraway?

Caraway
  • Digestive upset and bloating
  • Gas (flatulence)
  • Indigestion (dyspepsia)
  • Irritable bowel symptoms
  • Increasing breast milk (traditional)

Caraway is a common cooking spice that has long been used to ease gas, bloating, and indigestion. Some evidence suggests caraway oil—often combined with peppermint oil—may help with indigestion, but evidence for most other uses is limited. Food amounts are generally safe; concentrated oils and supplements should be used cautiously and discussed with your pharmacist or doctor.
