While doctors generally recommend that pregnant women focus on preventing migraines rather than treating them through medications, acetaminophen and triptans are possible treatment options that are not strongly linked to human birth defects. Some preventative medications that are relatively safe for pregnant women include beta-blockers such as propanolol and calcium channel blockers such as verapamil, according to WebMD.
The safest way to address migraines during pregnancy is to avoid triggering them and avoid the use of medications altogether. The first step is for sufferers to learn their own individual triggers by journaling information about their migraines, including their specific symptoms, food and drink consumed in the past 24 hours, changes in environment, and any treatments used. Some common triggers include chocolate, caffeine, foods containing MSG and nitrates, and aspartame, according to WebMD.
Pregnant women should avoid certain medications because of the possible dangers they pose to the mother or fetus, according to WebMD. Nonsteroidal anti-inflammatory drugs such as aspirin carry a possible risk of bleeding or miscarriage early during a pregnancy and may cause blood pressure complications during the third trimester. Pregnant women should also avoid narcotics because they can cause addiction in both the mother and unborn baby if used for too long.
