Other dose-related complaints include mild gastrointestinal upsets, unsteadiness, and, at much higher doses, drowsiness Hyponatremia and water intoxication have occasionally occurred and may be dose-related. Considerable concern exists regarding the occurrence of idiosyncratic blood dyscrasias with carbamazepine, including fatal cases of aplastic anemia and agranulocytosis. The mild and persistent leukopenia seen in some patients is not necessarily an indication to stop treatment but requires careful monitoring. The most common idiosyncratic reaction is an erythematous skin rash; other responses such as hepatic dysfunction are unusual.
