Side effects are dose-dependent. The most common include dizziness, blurred or double vision, nystagmus, ataxia, fatigue, headaches, nausea, vomiting, sleepiness, difficulty in concentration and mental sluggishness. Other rare side effects of<unk>  include severe low blood sodium (hyponatremia), anaphylaxis / angioedema, hypersensitivity (especially if 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<unk>  and 8-12% of those experience severe hyponatremia. Some side effects, such as headaches, are more pronounced shortly after a dose is taken and tend to fade with 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 people could experience severe sunburns as a result of sun exposure.<unk>  may lead to hypothyroxinemia. The well-known reduction in free and total thyroxine concentration may be due to both peripheral and central mechanisms.
