Update in migraine preventive treatment

Migraine is a prevalent disorder with high disability and socioeconomic costs. Preventive treatment has been shown to decrease headache frequency, improve quality of life and minimize the medical expenses. Although many medications have been proved effective, they are underutilized. For the past several years, significant progress has been made with the emerging options of calcitonin-gene related peptide (CGRP) monoclonal antibodies and antagonists. The choices of these medications depend on not only the evidences of effects and possible side effects of the medications but also comorbidities, preferences and even special considerations of the individual patient such as breast feeding and reproduction.
