[Headache treatment in an emergency unit of the city of Ribeirão Preto, Brazil].

Headache is one of the most common symptoms observed in clinical practice. It has a considerable economic impact and overburdens emergency rooms. In Brazil, most emergency rooms have no tryptans. The present study analyses the treatment provided by the Emergency Room of the University Hospital of Ribeirão Preto. In 1996, 1254 patients were treated for headache and 64 of them required hospitalization. Of the non-hospitalized (NH) patients, 77% had primary headache, as opposed to 29.7% of hospitalized patients. Of the patients with migraine, 83.6% improved with intravenous dipyrone, 66.7% improved with intramuscular diclofenac and 81.8% improved with intravenous chlorpromazine. The percentages of patients with tension-type headache who improved with the same drugs were 77.8%, 80% and 100%, respectively. Among NH patients, 16.3% improved without any medication. We conclude that the drugs used have similar efficacy profiles and costs and can be used at basic health unities. The major drawback is parenteral administration.
