Abstract

Objective: This study was conducted to review and synthesize current evidence on anti-calcitonin gene-related peptide (CGRP) therapies in women with menstrual-related migraine, during pregnancy and lactation, and while using hormonal contraception.

Background: Migraine disproportionately affects women, with prevalence peaking during reproductive years when hormonal fluctuations modulate neurovascular and nociceptive pathways, including CGRP signaling, that contribute to migraine susceptibility. Despite the established efficacy of anti-CGRP therapies-including monoclonal antibodies (erenumab, fremanezumab, galcanezumab, and eptinezumab) and gepants (ubrogepant, rimegepant, atogepant, and zavegepant)-evidence regarding their use across critical reproductive health contexts remains limited.

Methods: A systematic search of MEDLINE and Embase was conducted using MeSH terms and keywords related to migraine, CGRP-targeted therapies, and reproductive health contexts. Studies were screened independently by two reviewers. Data were extracted using standardized forms and synthesized narratively by clinical domain.

Results: Sixteen studies met inclusion criteria. For menstrual-related migraine, post hoc analyses and observational studies demonstrate that CGRP monoclonal antibodies reduce migraine frequency both during and outside the perimenstrual window (galcanezumab: -5.1 vs. -3.2 days, p < 0.001), although the perimenstrual period remains a time of relatively higher headache burden…
