Orally administered enoxaparin is poorly absorbed and even large oral doses should not lead to any serious consequences. This may be checked by plasma assays of anti-Xa and anti-IIa activities.Accidental overdose following parenteral administration may produce haemorrhagic complications. The anticoagulant effects can be largely neutralised by the slow intravenous injection of Protamine, but even with high doses of Protamine, the anti-Xa activity of enoxaparin sodium is never completely neutralised (maximum about 60%). The initial dose of Protamine depends on the dose of enoxaparin given and also consideration of the maximum recommended Protamine dose (50mg). Data on Protamine dosing in humans for enoxaparin overdose is extremely limited. The available data suggest that in the first 8 hours after enoxaparin administration 1mg Protamine should neutralise the effects of 1mg of enoxaparin. Where the dose of enoxaparin has exceeded 50mg, an initial dose of 50mg Protamine would be appropriate, based on the maximum recommended single protamine dose. Decisions regarding the necessity and dose of subsequent Protamine injections should be based on clinical response rather than measurement of anti Xa or anti XIIa results. The physician should also consider that the amount of enoxaparin in the body drops to 50% after 8 hours and 33% or less after 12 hours. The dose of Protamine should be adjusted depending on the length of time since enoxaparin was administered.
