Oxcarbazepine can cause clinically significant hyponatremia in 2.5% of patients. If oxcarbazepine is combined with other drugs that reduce sodium, the patient should be monitored. Signs of hyponatremia include nausea, drowsiness, confusion, and headache, and patients should be taught to report these symptoms. Increasing the dose of oxcarbazepine is not indicated. Rashes can indicate a serious drug reaction, and providers should be notified so that the oxcarbazepine can be withdrawn. Salt substitutes would compound the problem of hyponatremia.
