There is evidence to suggest that it may have additive anticonvulsant activity with valproate. However even in the absence of comprehensive evidence I certainly wouldn't recommend using it with anticonvulsant narrow therapeutic indexed medications) eg valproate, lithium, carbamazepine)Also, does it have any interactions or contraindications with any medications or conditions you are aware of? (Particularly seizures, ADD, Adderall, or SSRI/SSNRI's)
Theoretically, assuming an AMPA antagonism MOA, with the exception of selective medications acting on monamine transmission (atypical antipsychotics and triptans come to mind) there shouldn't be any interactions with SSRIs, SNRIs, TCAs- however before making an umbrella recommendation it would be pertinent to assess the individual, the specific medication, dose, indication.
