Ginkgo and Moclobemide

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

Moderate

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES

Why this applies to Moclobemide

Moclobemide falls under CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES — the group Ginkgo interacts with.

Theoretically, ginkgo might decrease levels of drugs metabolized by CYP2C19.
Some clinical research shows that a specific ginkgo leaf extract (Remembrance, Herbs Product LTD) 140 mg twice daily can induce CYP2C19 enzymes and potentially decrease levels of drugs metabolized by these enzymes. However, other clinical research shows that taking ginkgo 120 mg twice daily for 12 days has no effect on levels of drugs metabolized by CYP2C19.
Severity Moderate Likelihood Probable Evidence B

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for moclobemide: it's an antidepressant (a reversible MAO-A inhibitor) that your liver partly clears using an enzyme called CYP2C19. Some research suggests ginkgo can speed that enzyme up, which would clear moclobemide a little faster and might lower its levels. In plain terms, that could mean your antidepressant works less well, with symptoms like low mood or anxiety creeping back.

I want to be honest about how shaky this is. One study showed ginkgo nudging this enzyme, while another found no effect at all, so it's far from certain. Don't change anything on your own. If you take moclobemide and want to try ginkgo, run it by your pharmacist or doctor first so they can keep an eye on how you're feeling.

About Ginkgo

What is Ginkgo?

Ginkgo
  • Memory and cognitive support
  • Age-related mental decline
  • Circulation problems
  • Tinnitus (ringing in the ears)
  • Dizziness or vertigo

Ginkgo is one of the world's most popular herbal supplements, mostly taken to support memory and circulation. The evidence for these uses is mixed and generally weak, and it is not proven to prevent memory loss or dementia. It is usually well tolerated in healthy adults, but it can thin the blood, so talk to your pharmacist or doctor before using it.
