Dihydroergotamine (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). ⋯ This 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.
