One hundred and forty-nine (52.1%) safety reports reported only drug exposure in relation to pregnancy while 137 (47.9%) also included \u22651 pregnancy outcomes: maternal outcomes (n\u2009=\u200964), spontaneous abortion (n\u2009=\u200963), foetal growth restriction (n\u2009=\u20091), prematurity (n\u2009=\u20098), neonatal outcomes (n\u2009=\u200913), and poor breastfeeding (n\u2009=\u20091). No specific patterns of maternal, foetal and neonatal toxicity were observed. Spontaneous abortion was not disproportionally more frequently reported with erenumab, galcanezumab, fremanezumab and eptinezumab compared with the entire database (ROR 1.1, 95% confidence interval,
