Rhodiola and Sodium valproate

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

Minor

CNS DEPRESSANTS

Why this applies to Sodium valproate

Sodium valproate falls under CNS DEPRESSANTS — the group Rhodiola interacts with.

Theoretically, rhodiola might increase the risk of adverse effects when taken with CNS depressants.
A review of adverse event reports in Poland identified cases of excessive sedation, myoclonus, hypotension, and hallucinations when rhodiola was taken with haloperidol, diazepam, or alprazolam.
Severity Minor 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 sodium valproate (Epilim): this medicine can already make some people feel drowsy or foggy, and rhodiola is being looked at as a possible add-on that might nudge that sedation up a notch. The concern is theoretical and based only on scattered case reports, not solid studies, and those reports involved different sedating drugs (like diazepam and haloperidol), not valproate itself.

So this is a minor, low-evidence flag rather than a red alert. Still, if you do try rhodiola, keep an eye out for extra sleepiness, dizziness, or feeling unsteady. Since valproate also needs careful dosing, please check with your pharmacist or doctor before adding rhodiola rather than starting it on your own.

From our pharmacist’s overview on the Sodium valproate page

“Sodium valproate (Epilim) controls seizures and stabilizes mood, and the supplement list on this page warrants genuine care rather than a quick skim. Nine of the 173 ingredients on file carry a major rating, and most of the danger follows two patterns.”

About Rhodiola

What is Rhodiola?

Rhodiola
  • Fatigue and low energy
  • Stress and coping (adaptogen)
  • Mental performance and focus
  • Mild depression
  • Physical and exercise performance

Rhodiola is an herb traditionally used to fight fatigue and help the body cope with stress. Some small studies suggest it may modestly reduce fatigue and improve mood, but the evidence is limited and not strong. It is generally well tolerated for short-term use, but talk to your pharmacist or doctor before trying it, and avoid it during pregnancy and breastfeeding.
