Migraine Treatment in Emergency Departments of Brazil: A Retrospective Study of 2 Regions.

OBJECTIVE: This study describes the approaches, medications used, and time of care for migraineurs, who have been in emergency departments (ED) from 2 different regions of Brazil. METHODS: Retrospective, cross-sectional, observational, non-randomized study of migraine patients seen at 2 headache centers in Brazil. RESULTS: Eighty-four migraine patients (15 men and 69 women) were divided into 2 groups: chronic (19%, n = 16) and episodic migraineurs (81%, n = 68). In the ED, medications were used in the following order of frequency: dipyrone or metamizole (89.3%, 75/84), nonsteroidal anti-inflammatory drugs (57.1%; 48/84) opioids (51.1%; 43/84), metoclopramide (29.8%; 25/84), dexamethasone (28.6%; 24/84), chlorpromazine (13.1%; 11/84), and subcutaneous sumatriptan (7.1%; 6/84). The average time in the care center was 8.2 hours, but only 23 patients (27.4%) left the hospital with greater than 50% relief in headache severity. CONCLUSIONS: Dipyrone and nonsteroidal anti-inflammatories were the most used drugs, but nearly half received opioids. More efficient drugs were poorly used. Considering the number of patients leaving the hospital with headache relief, a changing treatment paradigm should be carried out in Brazil.
