migraine during pregnancy are a real problem because very few medications are felt to be safe during pregnancy. i don't normally recommend prevention medications during pregnancy (zoloft inderol and occasionally verapamil) unless the nausea/vomiting and dehydration from the headaches are causing problems with the pregnancy. we use a lot of phenergan for headaches during pregnancy but it causes drowsiness in some people. tylenol with codeine or percocet are the only other medications we use in pregnant women with headaches because they are generally considered safe. you might want to ask your ob/gyn for a referral to a headache specialist while you are pregnant. breastfeeding is a seperate issue because some medications (like percocet) are in breast milk at a higher concentration that in the mothers blood and other medications (like imitrex) are present at a much lower concentration in breast milk.
what is the course of treatment for pregnant women who have migraines?
