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
Serum (blood) toxic response. Blood is centrifuged to remove cellular components. Anti-coagulated blood yields plasma containing fibrinogen and clotting factors. Coagulated blood (clotted blood) yields serum without fibrinogen, although some clotting factors remain. Serum is an essential factor for the self-renewal of embryonic stem cells in combination with the cytokine leukemia inhibitory factor. The serum of convalescent patients successfully recovering (or already recovered) from an infectious disease can be used as a biopharmaceutical in the treatment of other people with that disease, because the antibodies generated by the successful recovery are potent fighters of the pathogen. Such "convalescent serum" (antiserum) is a
