SAN DIEGO — If a medical professional is trying to figure out the best medical treatment for a pregnant woman with headache, it may be helpful to review data from randomized clinical trials (RCTs). Well, make that data from the RCT. There's just been one, Northwestern Medicine obstetrician-gynecologist Catherine Stika, MD, told colleagues at the annual clinical and scientific meeting of the American College of Obstetricians and Gynecologists.
Only a single efficacy RCT has examined headache in pregnancy, said Stika. "Overall, we have very limited data in pregnancy to tell us exactly what to do," she added.
But ob.gyns. aren't entirely in the dark, according to medical specialists who spoke at the session. Expert opinion and fetal safety data offer insight into the best treatments, as does a new ACOG clinical practice guideline on headaches during pregnancy and post partum that was coauthored by the speakers.
And there's some good news: Pregnancy itself is often a good treatment for headaches.
Pregnant women often find relief from one kind of headache — migraine — as their estradiollevels rise, said Laura Mercer, MD, an ob.gyn. at the University of Arizona, Phoenix. "About half of patients will report that migraines are getting better as early as the first trimester, and upwards of 83% will say that their migraines are better by the time they're in their third trimester," she said. "What this means for us as obstetricians is that oftentimes we can actually discontinue preventative therapies for patients during pregnancy."
