Restarting Low-Molecular-Weight Heparin After Lumbar Puncture

LMWH (e.g., enoxaparin) should be restarted only after procedural hemostasis and after an interval long enough to minimize spinal hematoma risk. Recommendations for neuraxial procedures use delayed restart intervals based on LMWH dose intensity, with therapeutic-dose LMWH requiring longer delays than prophylactic dosing. [1], [2]
