A study found that the AUC of the active 
metabolite of 
bupropion was almost doubled when 
bupropion was given with 
valproate. An increase in 
valproate levels of almost 30% was seen in one patient. 
 Monitor for any evidence of increased 
toxicity (due to the raised 
bupropion metabolites or valproate). Note that 
bupropion is contraindicated in patients with 
epilepsy.
