[Clonazepam in painful syndromes of the head].

A study of 46 patients has shown that Clonazepam is an effective drug in preventing attacks of pain in essential trigeminal and glossopharyngeal neuralgia and in Sluder's syndrome. The therapeutic action of the drug is less evident in different types of migraine, among which only the combined headache presents good results to the treatment. The effective dose of this drug is generally not greater than 3 mg/die and does not give rise to side effects in long-term prescription.
