: Erenumab, a monoclonal antibody targeting the receptor of calcitonin gene related peptide (CGRP), is the first disease-specific and mechanism-based treatment approved for the prevention of migraine. Although the safety and tolerability data from randomized trials are clear, the physiological effects of CGRP rise reasonable concerns. We aimed to evaluate the current evidence for safety and tolerability related to erenumab use in migraine.: This review outlines the severe adverse events (AEs), common AEs, AEs leading to treatment discontinuation and AEs of special interest, reported in all phase 2, phase 3, open label and observational studies with erenumab in migraine. Individual safety reports were also included in the systematic review of evidence.: No safety and tolerability flags were detected in this review. The most common AE are local skin reactions and constipation. No severe AEs, or frequent AEs leading to treatment discontinuation were detected. Treatment is well tolerated. The only AE of interest that may play a role in decision making and treatment monitoring is constipation. These findings are in line with previous safety reports, further highlighting the substantial tolerability and safety profile of the modern anti-CGRP monoclonal antibodies for the prevention of migraine.
