Renal impairment Severe (CrCl <30 mL/min): Dosage reductions required Prophylaxis in abdominal surgery: 30 mg SC qDay Prophylaxis in hip or knee replacement surgery: 30 mg SC qDay Prophylaxis in medical patients with restricted mobility: 30 mg SC qDay DVT treatment (inpatient or outpatient) coadministered with warfarin: 1 mg/kg SC qDay Non-Q-wave myocardial infarction: 1 mg/kg SC qDay Treatment of acute STEMI (<75 years): 30 mg IV single bolus plus 1 mg/kg SC, THEN 1 mg/kg SC qDay Treatment of acute STEMI (>75 years): No initial bolus; maintenance of 1 mg/kg SC qDay

Hyper-sensitivity to either Enoxaparin, heparin or other low molecular weight heparins; major clotting disorders like history of thrombocytopenia, active gastro-intestinal ulcer or organic lesion likely to bleed, recent haemorrhagic vascular cerebral stroke. Although rare, cutaneous or systemic allergic reactions may occur.

Enoxaparin is a low molecular weight heparin w/ anticoagulant properties. It acts by enhancing the inhibition rate of activated clotting factors including thrombin and factor Xa through its action on antithrombin III.

Enoxaparin injection should not be administered by intramuscular route. Enoxaparin should be used with caution in conditions with increased potential for bleeding, such as impaired hemostasis, history of peptic ulcer, recent ischemic stroke, uncontrolled severe arterial hypertension, diabetic retinopathy, recent neuro or opthalmologic surgery and low weight patients. It is recommended that the platelet count be measured befored the initiation of the treatment and regularly thereafter during treatment. Lactation: Excretion in milk unknown; not recommended

1-10% Hemorrhage (1-4%),Elevation of serum aminotransferases (6%),Fever (5-8%),Local site reactions (2-5%),Thrombocytopenia (3%),Nausea (3%),Anemia (2%),Ecchymosis (3%) <1% Atrial fibrillation,Heart failure,Pulmonary edema,Pneumonia Potentially Fatal: Haemorrhagic complications.

Pregnancy Human data from a retrospective cohort study, suggest that enoxaparin does not increase risk of major developmental abnormalities Pregnancy alone confers increased risk for thromboembolism that is higher for women with thromboembolic disease and certain high risk pregnancy conditions; while not adequately studied, pregnant women with mechanical prosthetic heart valves may be at even higher risk for thrombosis; pregnant women with thromboembolic disease, including those with mechanical prosthetic heart valves and those with inherited or acquired thrombophilias, have an increased risk of other maternal complications and fetal loss regardless of type of anticoagulant used All patients receiving anticoagulants, including pregnant women, are at risk for bleeding; pregnant women receiving drug should be carefully monitored for evidence of bleeding or excessive anticoagulation Hemorrhage can occur at any site and may lead to death of mother and/or fetus; pregnant women should be apprised of potential hazard to fetus and mother if therapy is administered during pregnancy Lactation Unknown whether therapy is excreted in human milk; in lactating rats, passage of enoxaparin or metabolites in milk is very limited; there is no information available on effect of enoxaparin or metabolites on breastfed child, or on milk production; developmental and health benefits of breastfeeding should be considered along with mother's clinical need for therapy and any potential adverse effects on breastfed child from drug or from underlying maternal condition Excretion in milk unknown; not recommended

Increased risk of bleeding w/ anticoagulants, platelet aggregation inhibitors (e.g. dipyridamole, salicylates, NSAIDs, sulfinpyrazone). May increase bleeding w/ vit E.
