Spearmint and Benactyzine, Meprobamate

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

Moderate

CNS DEPRESSANTS

Why this applies to Benactyzine, Meprobamate

Benactyzine, Meprobamate falls under CNS DEPRESSANTS — the group Spearmint interacts with.

Theoretically, spearmint might alter the sedative effects of CNS depressants.
Animal research suggests that (-)-carvone, a major constituent of spearmint, has sedative effects. However, in humans, chewing spearmint-flavored gum induced arousal 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

Deprol combines meprobamate (a sedative that calms anxiety) with benactyzine. Both work on your central nervous system, so they can already make you feel drowsy, relaxed, or a little foggy. The concern here is purely theoretical: in animal studies, a compound in spearmint called carvone showed mild sedative effects, which might add to that calming action. Interestingly, in people, chewing spearmint gum actually seemed to wake them up, so the human picture is unclear.

Honestly, the spearmint in tea, gum, or cooking is very unlikely to cause any trouble. The only situation worth a quick chat is if you take concentrated spearmint supplements daily. If you notice extra grogginess, mention it to your pharmacist or doctor.

From our pharmacist’s overview on the Benactyzine, Meprobamate page

“Meprobamate does the heavy sedating in Deprol (benactyzine is its partner), and that is why 78 of the 105 supplements and herbs on this list demand real caution. They pile extra sedation on top of the drug's own, and most of the seven major-rated interactions sit in that group.”

  • Memory and focus

Spearmint is a common culinary mint that is generally safe in food and tea amounts.
