    BackgroundDihydroergotamine (DHE) is perceived to be associated with a higher risk of adverse pregnancy events, but it has significantly less vasoconstrictive and uterotonic effects compared with ergotamine, and has demonstrated no teratogenic effect in animals. The objectives of this study were to quantify the risk of major congenital malformations (MCMs), prematurity, low birth weight (LBW), and spontaneous abortions (SAs) associated with gestational use of DHE, triptans, and nonsteroidal anti-inflammatory drugs (NSAIDs).MethodsFour independent case-control analyses were conducted within the Quebec Pregnancy Registry: (1) MCM; (2) prematurity (<37 weeks of gestation); (3) LBW (birth weight <2500 g); (4) clinically detected SA. Exposure was defined dichotomously as use of DHE, triptan, and NSAIDs during pregnancy.ResultsOverall, 59,707 pregnant women met the eligibility criteria and were considered (53 [0.08%] used DHE, 139 [0.23%] triptans, and 2990 [5.01%] NSAIDs). Adjusting for potential confounders, gestational use of DHE was not significantly associated with the risk of MCM (odds ratio [OR]: 0.97; 95% confidence interval [CI]: 0.22-4.28), LBW (OR: 1.41; 95%CI: 0.25-7.80), or SA (OR: 1.97; 95% CI: 0.21-18.57). DHE use was, however, increasing the risk of prematurity (OR: 4.18; 95% CI: 1.34-12.99). In users of triptans, the OR for MCM was 1.49 (95% CI: 0.89-2.52), prematurity 0.76 (95% CI: 0.34-1.66), LBW 0.83 (95% CI: 0.31-2.25), and SA 2.65 (95% CI: 1.57-4.48). In users of NSAIDs, the OR for MCM was 1.20 (95% CI: 1.06-1.36), prematurity 1.10 (95% CI: 0.95-1.26), LBW 1.29 (95% CI: 1.08-1.54), and SA 2.97 (95% CI: 2.63-3.36).ConclusionsThis study showed that other than for prematurity, DHE use during pregnancy was similar to that of triptan use and was smaller than the risk associated with NSAID use.© 2012 American Headache Society.
