The chronic use of analgesics constitutes an important cause of cronicity and drug resistance in headaches. The high prevalence of headache`s cases, associated with increasingly easy access to symptomatic medications, eventually causes an uncontrolled and abusive use of these medications by the population. Because of this, the medication overuse headache ended up becoming an important disease entity in the present, with extensive publication in the literature. Objective: To recognize and evaluate the pattern of analgesic use and your interference in headaches in patients with headache assisted at the Serviço de Cefaleias e Algias Craniofaciais of the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto (ACEF). Materials and Methods: The study is observational, predominantly descriptive, prospective, double-blind, addressing randomly around 155 patients with headache, aged between 18 and 80 years, attended by doctors hired at ACEF. Patients who was attending in this outpatient clinic during the period of one year, will be submitted to a semi-structured, self-administered and anonymous questionnaire, composed of open and closed questions, especially prepared for this research, in order to evaluate the pattern of analgesic use and your interference in headaches. After the questionnaire is answered, the doctor who will perform the service will make the diagnosis of headache. At the end of the medical consultation, the investigator, without knowledge of the patient, will take possession of the questionnaires.
