Could three doses a day prevent clots in pregnancy better than two?
NCT ID NCT04861103
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking the blood thinner Lovenox three times a day works better than the standard twice-a-day schedule for pregnant women at high risk of blood clots. Pregnancy increases clot risk fivefold, and many women on the standard schedule don't get enough protection. The trial will enroll 12 pregnant women and measure blood thinner levels to see if three daily doses provide more consistent protection.
