Lexi-Drugs Online/Pediatric Lexi-Drugs Online, Enoxaparin,, Copyright © 1978-2008 Lexi-Comp, Inc, Hudson, OH 44236 They may be used for the treatment of severe heparin overdosage. Due to the overall negative charge of heparin, the positively charged protamine competes with the thrombin-binding site of heparin and effectively blocks its anticoagulation effect (Hirsh, Anand, Halperin, & Fuster, 2001 ). Heparin antagonists are substances which inhibit the anticoagulant action of heparin. Patients with hypersensitivity to fish (vertebrate, not shellfish) and those who have received protamine-containing insulin or previous protamine therapy may be at risk of hypersensitivity reactions.ĭavid, M., et al. Protamine sulfate is a specific reversal agent used to reverse the effect of heparin. More rapid infusion may result in hypotension. If the LMW heparin dose has been given within 3-4 hours give 1 mg protamine/1 mg of enoxaparin dose. If immediate reversal is required protamine sulfate will result in partial neutralization. Protamine should be given IV over 10 minutes. What is the antidote for heparin and enoxaparin Termination of the SQ injection generally will terminate the anticoagulant effect. If the LMW heparin dose has been given within 3-4 hours give 1 mg protamine/1 mg of enoxaparin dose. If initiating treatment more than 4 hours after last dose given, give 0.5 mg protamine/1 mg of enoxaparin.Ī second dose of 0.5 mg protamine /1mg of enoxaparin dose may be given if the PTT remains prolonged 2-4 hours after the initial dose. If immediate reversal is required protamine sulfate will result in partial neutralization. Termination of the SQ injection generally will terminate the anticoagulant effect.
