Cocoa and Valproic Acid

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

Moderate

VALPROATE

Why this applies to Valproic Acid

Valproic Acid falls under VALPROATE — the group Cocoa interacts with.

Theoretically, cocoa might reduce the effects of valproate and increase the risk for convulsions.
Cocoa contains caffeine. Animal research suggests that caffeine can decrease the anticonvulsant activity of valproate. However, the exact mechanism of this interaction is unclear.
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 gist for valproic acid and cocoa: cocoa naturally contains a little caffeine, and in animal studies caffeine seemed to blunt how well valproate calms down brain activity. In theory, that could make your seizure control a touch less reliable, which matters since valproic acid is your protection against seizures (or your mood and migraine support). The worry would be a breakthrough seizure if the medicine isn't working as well.

That said, this is theoretical and based only on lab and animal work, so I wouldn't lose sleep over a cup of hot cocoa or a chocolate treat now and then. Concentrated cocoa or caffeine supplements are where I'd be more cautious. If you use those regularly or notice any change in your seizures, check in with your pharmacist or doctor before making any changes.

About Cocoa

What is Cocoa?

Cocoa
  • Heart and blood vessel health
  • High blood pressure
  • High cholesterol
  • Mental focus and mood
  • Skin moisturizing (cocoa butter)

Cocoa is rich in plant compounds called flavanols that may modestly support blood vessel function and blood pressure, but most chocolate products are high in sugar, fat, and calories, which can offset any benefit. Enjoy cocoa as part of a balanced diet, and talk to your pharmacist before using concentrated cocoa supplements, especially if you have heart or blood pressure conditions.
