(HealthDay News) — The U.S. Preventive Services Task Force recommends low-dose aspirin for preeclampsia prevention in high-risk pregnant women. The findings are presented in a final recommendation statement published in the Annals of Internal Medicine.

Researchers from the U.S. Preventive Services Task Force (USPSTF) reviewed the evidence relating to the effectiveness of low-dose aspirin for preventing preeclampsia in women at increased risk. In addition, they examined the maternal and fetal harms of low-dose aspirin use during pregnancy.

Based on the evidence, the USPSTF recommends the use of low-dose aspirin (81 mg per day) as a preventive measure after 12 weeks of gestation for women at high risk for preeclampsia (Grade B recommendation).

The recommendation applies to asymptomatic pregnant women with increased preeclampsia risk, who have no contraindications or prior adverse reactions to low-dose aspirin.

“Most women are not at high risk for preeclampsia,” Michael L. LeFevre, MD, MSPH, chair of the USPSTF, said in a statement. “Before taking aspirin, pregnant women should talk to their doctor or nurse to determine their risk level and discuss if taking aspirin is right for them.”
