Interaction report

Kratom and Sodium valproate

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Kratom interacts with whole categories of medication. Sodium valproate falls into 2 of those categories, so it can interact with Kratom in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CNS DEPRESSANTS

1 of 2

Why this applies to Sodium valproate

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

Theoretically, concomitant use might increase the risk for adverse CNS depressant effects.
Kratom contains mitragynine, a mu-receptor agonist that may cause respiratory depression. Although results from animal research suggest that mitragynine causes less respiratory depression than the CNS depressant codeine, fatalities have been reported for patients who ingested a combination of kratom and O-desmethyltramadol, another mu-receptor agonist. Additionally, observational research suggests that adverse effects such as drowsiness and coma are more likely to occur in individuals taking kratom in combination with agents such as opioids and sedatives. Theoretically, ingesting kratom along with other CNS depressants can increase the risk of adverse effects, including drowsiness, coma, and/or severe or fatal respiratory depression.
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 explains PharmD, Clinical Pharmacist

Here's the simple version: both kratom and your sodium valproate (Epilim) can slow down the brain and nervous system. When you stack two things that have a calming, sedating effect, those effects can pile on top of each other. With valproate that might mean extra drowsiness, dizziness, foggy thinking, or feeling unsteady on your feet. Kratom's opioid-like compounds can also dampen breathing, so the worry is deeper sedation than you'd expect.

To be fair, this caution is theoretical, based on how these substances behave rather than solid studies in people on valproate. Still, real harms have happened when kratom was mixed with other sedating drugs. Please don't change anything on your own. Have a quick chat with your pharmacist or doctor before combining them.

SEROTONERGIC DRUGS

2 of 2

Sodium valproate also falls under SEROTONERGIC DRUGS.

Theoretically, taking kratom in combination with serotonergic drugs may increase levels of serotonin, increasing the risk of serotonin syndrome.
A 63-year-old male presented with possible serotonin syndrome after taking an unknown dose of kratom for up to 3 months along with serotonergic prescription medications bupropion, buspirone, desvenlafaxine, trazodone, and ziprasidone. It was hypothesized that kratom inhibited the cytochrome P450 3A4-, 2C9-, 2D6-, and 1A2-mediated metabolism of several of these serotonergic medications, consequently increasing systemic exposure to serotonin.
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 an honest take on pairing kratom with sodium valproate (Epilim). The interaction on file is grouped under serotonin-boosting drugs, but valproate isn't really a serotonergic medication in the way an antidepressant is. It's a mood stabilizer and anti-seizure drug, so the serotonin syndrome concern that drove this listing doesn't fit valproate well. The evidence here is also weak, just a single case report involving several other drugs, not valproate specifically.

That said, kratom acts on opioid receptors and can cause drowsiness and slowed breathing, which may add to valproate's own sedation. I wouldn't combine them without checking first. Please talk with your pharmacist or doctor before mixing kratom with valproate.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction 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.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

These ratings are for information only. Never start, stop, or otherwise change your therapy before speaking with your provider.
