Pregnancy increases the risk of blood clots, but many blood thinners can harm the developing baby. Heparin offers a unique solution, providing protection for mom without crossing the placenta to affect the fetus.

Why Heparin in Pregnancy?
During pregnancy, a woman's blood naturally becomes more prone to clotting. This protects against excessive bleeding during childbirth, but it also increases the risk of dangerous blood clots. Some women, especially those with certain health conditions, need extra protection. Heparin, particularly low molecular weight heparin (LMWH), is the preferred blood thinner because it doesn't cross the placenta to affect the baby.
When is it Recommended?
Heparin might be prescribed if you have a history of blood clots, certain heart conditions, or inherited clotting disorders. It's also used to prevent miscarriage in women with antiphospholipid syndrome. The decision to use heparin is always individualized, weighing the potential benefits against any risks.
Dosing and Monitoring
LMWH is usually given as a daily injection under the skin. The dose may need to be adjusted as your pregnancy progresses and your weight changes. While routine monitoring isn't always necessary, your doctor will keep a close eye on your health. They may check your platelet count and, in some cases, measure heparin levels in your blood.
