Motherwort and Buprenorphine Hydrochloride

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

Moderate

CNS DEPRESSANTS

Why this applies to Buprenorphine Hydrochloride

Buprenorphine Hydrochloride falls under CNS DEPRESSANTS — the group Motherwort interacts with.

Theoretically, taking motherwort concomitantly with other CNS depressants may increase the risk of sedation.
Motherwort has been reported to cause CNS depression and sedation.
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: buprenorphine (Belbuca) already calms the nervous system, which is how it eases severe pain. Motherwort has been reported to have its own mild calming, sedating effect. Put the two together and those effects could stack up, so you might feel extra drowsy, dizzy, foggy, or short of breath. This isn't about motherwort changing how your body breaks the drug down, it's just two sedating things adding up.

I want to be honest that this concern is theoretical, based on how each one behaves rather than strong human studies. Still, because buprenorphine is a serious pain medicine, I'd run it by your pharmacist or doctor before adding motherwort, and never start or stop anything on your own.

About Motherwort

What is Motherwort?

Motherwort
  • Anxiety and stress
  • Heart palpitations
  • Menstrual discomfort
  • Menopausal symptoms
  • Insomnia

Motherwort is a traditional herb in the mint family long used for anxiety, heart palpitations, and women's reproductive complaints, but solid human evidence is very limited. It should be avoided during pregnancy and breastfeeding, and anyone with a heart condition or taking heart or blood-thinning medicines should talk to a doctor or pharmacist before using it.
