Key clinical point: A preconception history of migraine showed no significant association with the risk for spontaneous abortion (SAB); however, routine use of medication, suggesting more severe migraine, may confer a greater SAB risk.
Major finding: Preconception migraine history did not increase the risk for SAB (adjusted hazard ratio [aHR] 1.03; 95% CI 0.91-1.16), but daily migraine medication use (aHR 1.38; 95% CI 0.81-2.35), use of prescription migraine prophylaxis medication (aHR 1.43; 95% CI 0.72-2.84), or analgesic/caffeine medication use (aHR 1.42; 95% CI 0.99-2.04) showed a modest but non-significant association with SAB risk.
Study details: This study evaluated 7890 participants from an ongoing prospective study who conceived during follow-up and had or did not have a preconception diagnosis of migraine or migraine medication use, of which 1537 experienced SAB.
Disclosures: This study was funded by the National Institute of Child Health and Human Development, US National Institutes of Health. The authors declared no conflicts of interest.
