Thromboprophylaxis is increasingly advocated in pregnancy for certain clinical conditions. Low molecular weight heparins offer potential benefit over unfractionated heparins with increased bioavailability and a longer half-life, thus allowing for once daily administration. This study aims to determine if monitoring of anti-Xa activity is necessary in pregnant women undergoing thromboprophylaxis. Twenty-five pregnancies were prospectively followed where either tinzaparin or enoxparin was employed for thromboprophylaxis. Once the anti-Xa levels were in the thromboprophylactic range (0.03-0.5 U/ml) no patient required a change of dose. Frequent monitoring of Anti-Xa levels, once in the thromboprophylactic range, may not be required.
