Transcript: You know Tylenol is OK while you’re pregnant, but what if your condition is more pressing than a muscle ache? When you are pregnant, you’ll still need to deal with all of the day-to-day health issues that plague all of us. One common question women have is whether it’s safe to take an over-the-counter anti-diarrheal medication. In fact, taking Imodium while you are pregnant can be a smart precaution, since consistent diarrhea can lead to dangerous dehydration. Some women complain of motion sickness during pregnancy, and want to know what treatment options are safe. If you’re among them, it’s fine to take an OTC aid, like Dramamine, to combat nausea. Yet another common pregnancy condition is insomnia. Unfortunately, no sleeping aids have been shown to be completely safe for a fetus. While two medications—Ambien and Benadryl—are probably fine, studies on their effects have thus far been limited to animals. More intense sleep medications, like Lunesta and Sonata, may cause metabolism and brain damage to a fetus, and should be avoided. If you are unfortunate enough to get a migraine headache while you are pregnant, it is probably okay to take narcotics, like codeine, to ease the ache. But older migraine medications, like Depakote and Fiorinal, could lead to neural birth defects or paralyzation. It’s always smart to be cautious during pregnancy, so talk to your doctor before taking any kind of medication.
