The medication for habitual abortion should be used symptomatically according to the cause. If the pregnant woman has a pre-thrombotic state and her blood is hypercoagulable, she can be treated with small doses of aspirin and low molecular heparin before or during pregnancy. If a pregnant woman has diabetes, she can be treated with insulin or even oral hypoglycemic drugs throughout pregnancy. If a pregnant woman has hypothyroidism, she can be treated with oral eugenol supplements during pregnancy. If a pregnant woman does not receive good supplements, her baby may be congenitally hypothyroid and even have the risk of mental retardation.
