Carbamazepine is an antiepileptic of choice in partial and generalized epilepsies, accepted for use in children due to its low central depressant capacity. Also it is used in trigeminal neuralgia and neuropathic pain. Not recommended in absence crisis or myoclonic seizures. It is used as a first-line treatment for partial seizures, tonic-clonic, trigeminal glossopharyngeal neuralgia and as a stabilizer of mood to treat bipolar disorder.

Carbamazepine acts by reducing the release of glutamate, stabilizes the neuronal membranes and depresses the turnover of dopamine and noradrenaline.

SIDE EFFECTS

There are no specific data in children.

The most serious adverse reactions are those that can appear in blood, skin, liver and cardiovascular system. Especially at the beginning of treatment, if the dose is too high certain types of common or common adverse reactions occur, eg adverse effects on the CNS (dizziness, headache, ataxia, somnolence, fatigue, diplopia); gastrointestinal disorders (nausea, vomiting) and allergic skin reactions.

The dose-dependent adverse effects usually remit after a few days, spontaneously or after a transient dose reduction. The appearance of adverse reactions on the CNS may be indicative of a relative overdose or of significant fluctuations in plasma levels. In these cases it is advisable to monitor plasma levels.

Disorders of blood and lymphatic system: leukopenia, eosinophilia, thrombocytopenia.

Endocrine disorders: edema, fluid retention, weight gain, hyponatremia and reduction of blood osmolarity due to an effect similar to that of antidiuretic hormone (ADH), leading in rare cases to watery intoxication accompanied by lethargy, vomiting, headaches, confusional, neurological disorders.

Nervous system disorders: dizziness, ataxia, somnolence, fatigue, headache, diplopia, accommodation disorders (eg, blurred vision).

Gastrointestinal disorders: nausea, vomiting, dry mouth.

Hepatobiliary disorders: increase in gamma-GT (due to hepatic enzyme induction), usually without clinical relevance, increase in blood alkaline phosphatase.

Skin and subcutaneous tissue disorders: allergic dermatitis, urticaria, which can be serious.

CONTRAINDICATIONS
