Which route is used to administer enoxaparin for deep vein thrombosis prevention?

• A. Intravenous Infusion
• B. Subcutaneous Injection
• C. Oral Tablet
• D. Topical Cream

Answer: (B)

Enoxaparin for deep vein thrombosis prevention is given by subcutaneous injection. This route provides predictable anticoagulant effects with convenient dosing and avoids the need for IV access. It is not effective to give enoxaparin orally because it is poorly absorbed from the GI tract, and it is not used topically, since a cream would not deliver systemic anticoagulation. While unfractionated heparin can be given by IV infusion, enoxaparin is formulated for subcutaneous use and is dosed accordingly for prophylaxis.
