Answer: In most cases, no, although there are specific circumstances in which your caregiver might advise you to take a very small daily dose. While it's highly unlikely that taking a single dose of aspirin in early or midpregnancy will have any harmful effect, the drug can cause problems for your baby (and you) when taken regularly in normal adult doses while you're pregnant, so it's best to avoid it altogether during this time. However, if you're already taking a prescribed dose of aspirin for a specific condition, you may need to continue taking it, but you should check with your healthcare provider before taking any aspirin during pregnancy or while you're trying to conceive. Here's why: Studies have linked aspirin to various pregnancy complications. A few studies show that taking aspirin around the time of conception and in early pregnancy is associated with an increased risk of miscarriage. And some researchers believe that taking aspirin at adult doses in pregnancy might affect the baby's growth and may slightly increase the risk of a placental abruption. Finally, taking full-dose aspirin later in pregnancy might delay labor and increase the risk of heart and related lung problems in your newborn, and bleeding complications for you and your baby. However, in certain situations, your caregiver may advise you to take a small dose of aspirin each day (usually no more than one-quarter of the normal adult dose), and most experts believe this low-dose aspirin therapy is safe. One example: Some experts believe that women with a condition called antiphospholipid syndrome (diagnosed in women who have specific antibodies in their blood and who also have either have a history of blood clots or certain types of pregnancy problems) benefit from taking low-dose aspirin in addition to a drug called heparin beginning early in pregnancy. Other research shows that some women at high risk for preeclampsia (including women with chronic hypertension, severe diabetes, or kidney disease, or who had severe preeclampsia in a prior pregnancy) may benefit from low-dose aspirin therapy, though not everyone agrees on who is a good candidate for this treatment. So unless your healthcare provider prescribes it, you should avoid taking aspirin altogether, as well as other NSAIDs (non-steroidal anti-inflammatory drugs), such as ibuprofen (Advil, Motrin) and naproxen sodium (Aleve), and ketoprofen (Orudis) and others, which can have similar affects. Check the labels of all over-the-counter drugs (or better yet, check with your caregiver or pharmacist) before taking them to make sure they don't contain NSAIDs. (It can be hard to tell because some products list their ingredients under different names; aspirin is sometimes called "salicylate" or "acetylsalicylic acid," for example.) When you need to take something for pain relief while you're pregnant, acetaminophen (Tylenol) is considered safe to use as directed on the label."
