What is the recommended dosage of aspirin for preventing preeclampsia as per USPSTF guidelines?

The recommended dosage of aspirin for preventing preeclampsia, according to the U.S. Preventive Services Task Force (USPSTF) guidelines, is 81 mg per day. This dosage is specifically suggested for pregnant individuals who exhibit a higher risk for preeclampsia, as it has been shown to effectively lower the incidence of this condition. The evidence supporting this recommendation highlights a balance between the benefits of reduced risk for preeclampsia and the safety of the dosage. Studies indicate that lower doses, such as 81 mg, are both effective in preventing the condition and associated with fewer side effects compared to higher doses.

Other dosages, while potentially effective in different contexts, have not been established as the standard recommended dose for this specific preventive intervention. This is why the 81 mg daily dosage is highlighted as the optimal choice in current preventive strategies.
