FG was started on carbamazepine 1 month ago during an inpatient psychiatric admission for a manic episode of bipolar disorder. His serum level became therapeutic and he achieved remission during this admission, but upon presentation to clinic today you notice that he seems a little more restless and his speech is rapid. He reports adherence to medications. You’re concerned that he’s decompensating. Labs performed in the morning indicate a carbamazepine serum level of 3.2μg/mL. What is the most appropriateexplanation for this current presentation?
