Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Discuss inositol supplementation with your neurologist or psychiatrist before starting if you take valproate. Monitor mood stability and seizure control closely if used together.
Why this interaction occurs
Valproic acid exerts some of its mood-stabilizing and anticonvulsant effects by depleting inositol through inhibition of inositol monophosphatase. Supplementing with inositol may partially counteract this mechanism, potentially reducing valproate's therapeutic efficacy in bipolar disorder or epilepsy.
Evidence
Evidence level: moderate.
