Does aspirin play a role in preventing miscarriage?

Generally, aspirin is not a medication used for maintaining pregnancy and therefore has no effect in preventing miscarriage. Aspirin is an organic compound and a non-steroidal anti-inflammatory drug (NSAID), which is typically not indicated for fetal protection. The detailed explanation is as follows:

Aspirin belongs to the class of non-steroidal anti-inflammatory drugs and is a derivative of salicylic acid. It can be used to relieve mild to moderate pain, such as toothache, headache, neuralgia, and muscle soreness, but it does not have any role in preserving pregnancy. Clinically, aspirin is primarily used to reduce fever associated with conditions like the common cold or influenza, and to treat rheumatic pain. Additionally, aspirin inhibits platelet aggregation and may be used in the prevention of cerebral ischemic attacks, thrombus formation related to heart valve disorders or venous insufficiency, or following certain surgeries. In obstetrics, aspirin may be applied in pregnant women with pre-thrombotic conditions or to prevent the development of severe preeclampsia and eclampsia. However, unless specifically indicated, pregnant women should not take aspirin casually.

Medications available for maintaining pregnancy include oral and vaginal formulations. Common oral medications include progesterone capsules, dydrogesterone tablets, Baotailing capsules, and Baotai pills. Vaginal preparations mainly include progesterone vaginal sustained-release gel and progesterone suppositories. Given the wide variety of these medications, appropriate selection should be made under a physician’s guidance based on the specific stage of pregnancy.

If any discomfort occurs during pregnancy, it is recommended to seek medical advice from a specialist and use medications only as directed. Pregnant women should follow their doctor's recommendations and attend regular prenatal check-ups at a reputable hospital's obstetrics department.
