Wormwood and Divalproex Sodium

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

Moderate

ANTICONVULSANTS

Why this applies to Divalproex Sodium

Divalproex Sodium falls under ANTICONVULSANTS — the group Wormwood interacts with.

Theoretically, taking wormwood might interfere with the effects of anticonvulsant drugs.
Thujone, a constituent of wormwood, has convulsant 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

Here's the concern with pairing wormwood and Depakote (divalproex sodium). Wormwood contains a compound called thujone, which in higher amounts can actually trigger seizures. Since you're taking Depakote to keep seizures under control (or to steady mood or prevent migraines), adding something that pushes in the opposite direction could work against the medication you're relying on.

I want to be honest about the evidence here: this is mostly theoretical, based on lab and animal findings rather than real patient reports, so it's not a guaranteed problem. Still, when seizure control is on the line, I'd rather you play it safe. The thujone in wormwood is the part that matters, and concentrated supplement doses are the real worry. Before adding wormwood, please check with your pharmacist or doctor first.

About Wormwood

What is Wormwood?

Wormwood
  • Digestive upset and poor appetite
  • Intestinal parasites
  • Crohn's disease symptoms
  • Bitter tonic for indigestion
  • Flavoring in absinthe and vermouth

Wormwood is a very bitter herb traditionally used to stimulate appetite and ease digestion, and it has early research interest in Crohn's disease. It contains thujone, which can be toxic in large amounts, so it should only be used short-term in controlled doses. Talk to a pharmacist or doctor before using it, and avoid it if you are pregnant or breastfeeding.
