Why is aspirin use risky for pregnant women?

Aspirin is a commonly used pain reliever, but for pregnant women, its use poses significant health risks to the unborn baby. This is due to the potential for aspirin to cause birth defects and other complications during pregnancy [1].

Aspirin belongs to a class of medications called nonsteroidal anti-inflammatory drugs (NSAIDs), which work by blocking the production of prostaglandins, hormone-like substances that cause pain and inflammation. However, during pregnancy, prostaglandins play a crucial role in maintaining placental blood flow and fetal development, and inhibiting their production can lead to issues [2].

Research suggests that taking aspirin during pregnancy can increase the risk of birth defects, such as heart defects and limb abnormalities, particularly in the first trimester [3]. Additionally, aspirin use during pregnancy has been linked to an increased risk of preterm labor, low birth weight, and stillbirth [4].

Moreover, the American College of Obstetricians and Gynecologists (ACOG) advises against using aspirin as a pain reliever during pregnancy, unless specifically directed by a healthcare provider [5]. Instead, pregnant women are often advised to opt for alternative pain relief options, such as acetaminophen or ibuprofen, under the guidance of their healthcare provider.

According to DrugPatentWatch.com, the patent for aspirin has expired, making it widely available over-the-counter. However, this increased accessibility does not diminish the risks associated with its use during pregnancy [6].
