Levetiracetam and Vitamin B6: what the published research says

PubMed indexes 8 records that name Levetiracetam and Vitamin B6 together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Levetiracetam and Vitamin B6. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

8 studies naming Levetiracetam and Vitamin B6.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Current evidence for adjunct pyridoxine (vitamin B6) for the treatment of behavioral adverse effects associated with levetiracetam: A systematic review.

Epilepsy & behavior : E&B · 2023 · PMID 36791631

Systematic ReviewHuman subjects

“Data published within the last three years add to earlier evidence suggesting that PN might be effective in the treatment of NPAEs associated with LVT. However, the quality of evidence remains poor and only a few prospective trials have been published. Data from placebo-controlled trials are still largely lacking. Currently, there is insufficient evidence to justify any firm recommendation for PN supplementation to treat NPAEs associated with LVT.”

Besag et al. · Authors' conclusion

Names both Levetiracetam and Vitamin B6 in its title.

Pyridoxine supplementation for levetiracetam-related neuropsychiatric adverse events: A systematic review.

Epilepsy & behavior : E&B · 2020 · PMID 31917143

Systematic ReviewHuman subjects

“This systematic review suggests that pyridoxine might be of benefit in relieving LEV-related NPAEs. However, the quality of the evidence is poor, and better-designed prospective studies that include quantitative as well as qualitative data are needed to define the role of pyridoxine in the management of LEV-related NPAEs.”

Romoli et al. · Authors' conclusion

Names both Levetiracetam and Vitamin B6 in its title.

Pyridoxine supplementation for levetiracetam-related neuropsychiatric adverse events in pediatric and adolescent epilepsy: a prospective, double-blind, randomized, placebo-controlled trial.

Epilepsy & behavior : E&B · 2025 · PMID 40913882

Randomized Controlled Trial

“While pyridoxine did not significantly reduce behavioral scores compared to placebo at the study endpoint, the greater improvement in change scores over time suggests potential benefit in mitigating levetiracetam-associated NPAEs. Pyridoxine may serve as safe adjunctive therapy for patients who have behavioral side effects while maintaining seizure control.”

Thananowan et al. · Authors' conclusion

Names both Levetiracetam and Vitamin B6 in its title.

Can Pyridoxine Successfully Reduce Behavioral Side Effects from Levetiracetam?: A Critically Appraised Topic.

The neurologist · 2023 · PMID 37083708

Randomized Controlled Trial

“This study suggests that pyridoxine for the treatment of levetiracetam-induced behavioral side effects may result in modest improvement, although many limitations prevent conclusive results. There remains a need for a double-blinded, randomized control trial in both the adult and pediatric populations.”

Chhabra et al. · Authors' conclusion

Names both Levetiracetam and Vitamin B6 in its title.

Pyridoxine for treatment of levetiracetam-induced behavioral adverse events: A randomized double-blind placebo-controlled trial.

Epilepsy & behavior : E&B · 2022 · PMID 36228485

Randomized Controlled Trial

“Although this study showed no statistically significant beneficial effects of pyridoxine on the behavioral adverse effects of levetiracetam, placebo-controlled trials with a larger size and higher doses are needed to determine whether it is effective or not.”

Cheraghmakani et al. · Authors' conclusion

Names both Levetiracetam and Vitamin B6 in its title.

Amelioration of Levetiracetam-Induced Behavioral Side Effects by Pyridoxine. A Randomized Double Blind Controlled Study.

Pediatric neurology · 2021 · PMID 33823377

Randomized Controlled Trial105 participants

“These data provide clinicians with pertinent evidence-based information that suggests that a trial of pyridoxine in patients who experience behavioral side effects due to the use of levetiracetam may avoid unnecessary change of antiseizure medications.”

Mahmoud et al. · Authors' conclusion

Names both Levetiracetam and Vitamin B6 in its title.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Levetiracetam, Vitamin B6, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
