Oxcarbazepine experienced with carbamazepine, toxic epidermal necrolysis, Stevens–Johnson syndrome, and thoughts of suicide. Measurement of serum sodium levels should be considered in maintenance treatment or if symptoms of hyponatremia develop. Low blood sodium is seen in 20-30% of people taking oxcarbazepine and 8-12% of those who have oxcarbazpine-induced hyponatremia experience severe hyponatremia. Some side effects (such as headache) are more pronounced shortly after a dose is taken and tend to fade with the passage of time (60 to 90 minutes). Other side effects include stomach pain, tremor, rash, diarrhea, constipation, decreased appetite and dry mouth. Photosensitivity is a potential side-effect and
Hyponatremia saline is only recommended in those with significant symptoms and occasionally those in whom the condition was of rapid onset. Low volume hyponatremia is typically treated with intravenous normal saline. SIADH is typically treated with fluid restriction while high volume hyponatremia is typically treated with both fluid restriction and a diet low in salt. Correction should generally be gradual in those in whom the low levels have been present for more than two days. Hyponatremia occurs in about 20% of those admitted to hospital and 10% of people during or after an endurance sporting event. Among those in hospital, hyponatremia
