Renal effects lamotrigine

In 103 children with cranial diabetes insipidus, 3 children who started or had an increase in dose of lamotrigine needed a larger dose of desmopressin, suggesting an effect on the renal tubule or on drug clearance (76). Lamotrigine also increased desmopressin dosage requirements in two other children with cranial diabetes insipidus (78). 

The possibility of renal dysfunction as a rare adverse effect should be considered. The patient had a history of allergic reactions to lithium, carbamazepine, clozapine, haloperidol, and lamotrigine.
