Overview
Aspirin, or acetylsalicylic acid, is a common over-the-counter NSAID used for pain relief and fever reduction. During pregnancy, its use requires careful consideration due to potential effects on the fetus. Low-dose aspirin (typically 81 mg daily) is sometimes recommended by healthcare providers, while higher doses are generally discouraged. According to ACOG guidelines, low-dose aspirin may help prevent preeclampsia in high-risk women.
Safety Details
Aspirin can cross the placenta, potentially leading to mechanisms such as inhibition of prostaglandin synthesis, which may affect fetal development. High doses (over 150 mg) have been linked in peer-reviewed studies to risks including premature closure of the ductus arteriosus and increased bleeding tendencies. FDA labeling advises against use in the third trimester for non-low-dose forms. Low-dose regimens, however, show a favorable safety profile in large trials for specific indications, with minimal placental transfer impact at 81 mg.
Trimester Guide
First Trimester: Generally avoided unless prescribed, as high doses may increase miscarriage risk per some observational data. Low-dose aspirin may be started later if indicated.

Second Trimester: Low-dose aspirin (81 mg) is often initiated between 12-16 weeks for preeclampsia prevention in at-risk patients, per ACOG 2020 recommendations.
Third Trimester: High-dose aspirin should be avoided due to risks of fetal ductus arteriosus closure and bleeding complications. Low-dose may continue under medical supervision until delivery.
Alternatives/Tips
Safe alternatives include acetaminophen (up to 3,000 mg/day as needed, per FDA) for pain and fever. Non-drug options like rest, hydration, and prenatal yoga can help manage headaches. Always discuss any medication with your OB-GYN before use.
When to Consult Your Doctor
Contact your healthcare provider immediately if considering aspirin for any reason during pregnancy. They can assess your individual risk factors, such as history of preeclampsia or clotting disorders, and recommend appropriate dosing or alternatives based on current evidence.
