General Drug Information and Indications

Low-molecular-weight heparin for prevention and treatment of thromboembolic disease in cats and dogs. Low-molecular-weight heparin (LMWH — enoxaparin sodium). Mechanism: binds antithrombin III → potentiates inhibition of Factor Xa (primarily) and thrombin → anticoagulant effect. Predictable pharmacokinetics; subcutaneous bioavailability ~92%. Less monitoring needed than unfractionated heparin. Renally cleared; caution in renal impairment. Key information Refrigerate. Subcutaneous injection only. Do not aspirate before injection. Low molecular weight heparin — anti-Xa monitoring available. Incompatible with other drugs in same syringe. Dose adjustment in renal impairment.

How to Give this Medication

SQ injection: administer SQ (never IM or IV bolus). Pinch skin into a fold; inject into abdominal or lateral thoracic skin fold. Alternate sides for repeat doses. Do not expel air bubble from pre-filled syringe before injection. Store refrigerated (2–8°C); do not freeze. If a dose is missed Administer as soon as you remember. If it is almost time for the next scheduled dose, skip the missed dose and resume the normal schedule. Never double up doses to make up for a missed one. Enoxaparin is given once or twice daily — consistency is important for anticoagulation. Contact your veterinarian if you are unsure about timing.

Side Effects

Hemorrhage: hematoma at injection site, internal bleeding. Thrombocytopenia (HIT — less common with LMWH than UFH). Pain/bruising at SQ injection site. Hyperkalemia. Overdose: no specific antidote (partially reversed by protamine).
