Adding quetiapine to carbamazepine.
- Carbamazepine is principally metabolized by CYP3A4, and is a potent inducer of CYP1A2, CYP2C9, CYP3A4 and UDP-glucuronosyltransferases.
- Quetiapine is principally metabolized by CYP3A4 to active and inactive metabolites.
- Carbamazepine can reduce quetiapine serum concentration, possible below therapeutic range. 
- Add quetiapine according to the general dosing advice and increase dose based on clinical effect or serum concentration.
