Sassafras 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 Sassafras interacts with.

Theoretically, concomitant use of sassafras with drugs with sedative properties may cause additive 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

Deprol combines meprobamate, a sedative used for anxiety, with benactyzine. Sassafras itself has a mild calming, sedative-type quality, so the worry here is simple: putting two things together that both relax the nervous system may add up. You could feel more drowsy, dizzy, foggy, or unsteady than you would expect from the medication alone.

I want to be honest about how soft this concern is. It's theoretical, based on how each acts in the body rather than real reports of problems. The bigger issue with sassafras is its safrole content, which the FDA banned in food because of liver and cancer risks, so I'd avoid swallowing it regardless. If you use it, please check with your pharmacist or doctor first.

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.”

About Sassafras

What is Sassafras?

  • Digestive complaints
  • Cold and flu symptoms
  • Joint and muscle aches
  • Skin conditions (topical folk use)
  • As a flavoring agent (traditional root beer)

Sassafras is an aromatic North American tree whose root bark and oil were once popular in teas and as a flavoring, but it contains safrole, a compound the FDA has banned in foods because it can cause cancer and liver damage. There is no good evidence it safely treats any health condition, and most experts recommend avoiding internal use. If you want the flavor, choose products that are labeled safrole-free.
