- This combination of drugs may have possible synergistic effects. However, the pharmacokinetic drug interactions will influence the plasma levels. Dose adaptation is recommended for this combination. [1]

- Start carbamazepine with a daily dose of 200 mg and increase dose based serum concentration if necessary. Check lamotrigines effect after 2 weeks of therapy and adapt dose if necessary. [2]

- Abrupt stop of carbamazepine can cause serious lamotrigine rash as lamotrigine levels increase.[3]
- Carbamazepine likely speeds the metabolism of lamotrigine, but the clinical significance is unclear.[4][5]
- Lamotrigine may increase blood levels of carbamazepine metabolites, which can result in neurotoxicity (data about this are contradictory).[4][5]
- These two agents have less significant pharmacologic interactions than do lamotrigine and valproate.[4][5]
