Kudzu and Sodium valproate

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

Moderate

HEPATOTOXIC DRUGS

Why this applies to Sodium valproate

Sodium valproate falls under HEPATOTOXIC DRUGS — the group Kudzu interacts with.

Theoretically, concomitant use might have additive hepatotoxic effects.
There is some concern that kudzu can adversely affect the liver.
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 thing to know about sodium valproate (Epilim): it's a medicine that, on its own, can sometimes be hard on the liver. That's why your doctor may check liver bloodwork now and then while you take it. Kudzu has also raised some flags for the liver, so the worry here is simple addition: two things that may stress the liver being taken together.

I want to be honest about how strong this concern is. It's theoretical, based on how each one works, not on real-world reports of people getting hurt by the combo. Still, since valproate already carries liver risk, I'd loop in your pharmacist or doctor before adding kudzu, and watch for yellowing skin or eyes, dark urine, belly pain, or unusual tiredness.

About Kudzu

What is Kudzu?

Kudzu
  • Alcohol cravings and reduction

  • Heart and blood vessel health
  • Hangover relief
  • Traditional Chinese medicine (Ge Gen)

Kudzu is a fast-growing vine whose root has long been used in traditional Chinese medicine and is now studied mostly for reducing alcohol intake. Early research is promising for cutting back on drinking, but evidence for most other uses is weak. Talk with your pharmacist or doctor before trying it, and avoid it during pregnancy and breastfeeding.
