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
Hypotonic hyponatremia ADH secretion. As a result, the kidneys of such patients recover water and produce a fairly concentrated urine. Treatment is simple (if not without risk) — simply restore the patient's blood volume, thereby turning off the stimulus for ongoing ADH release and water retention. It is worth considering separately, the hyponatremia that occurs in the setting of diuretic use. Patients taking diuretic medications such as furosemide (Lasix), hydrochlorothiazide, chlorthalidone, etc., become volume depleted. That is to say that their diuretic medicine, by design, has caused their kidneys to produce more urine than they would otherwise make. This extra urine represents
