Symptoms of overdose of protamine include hypertension, and possible hemorrhage due to paradoxical anticoagulation with higher doses (eg > 100mg). Protamine sulfate is a medication that is used to reverse the effects of heparin. For example, if 30-60 minutes have elapsed since heparin was injected intravenously, 0.5-0.75mg Description: Protamine sulfate, a protein derived from the sperm of salmon and other fish species, is a chemical antagonist of heparin. No more than 50mg of protamine sulfate should be given in any one dose. <1/2 hr: 1-1.5 mg/100 units of heparin.

Overdosage with intravenous injection or intravenous infusion of unfractionated heparin (if 60–120 minutes lapsed since overdose) 375–500 micrograms (max. per dose 50 mg), to be administered at a rate not exceeding 5 mg/minute, to neutralise each 100 units of unfractionated heparin. 309 Protamine has been used to neutralize anticoagulation due to unfractionated heparin administration (UFH) after cardiac bypass surgery in more than 2,000,000 patients yearly. A dose of protamine is given, by drip administered over several minutes, once the patient is off-pump, when extracorporeal circulation and anticoagulation are no longer needed. Depending on dose received and renal function, protamine reversal may not be necessary due to dalteparin metabolism. (max. per dose 50 mg), 50–100% of the total dose to be given by intravenous injection (rate not exceeding 5 mg/minute), then give any remainder of dose by intravenous infusion over 8–16 hours, 1 mg neutralises approx. 100 units of unfractionated heparin. Depends on the amount of heparin to be neutralised. Dose of protamine (mg) to neutralize 100 units of heparin. Protamine Sulfate Injection, USP-PI-ENG-v1.1-Clean Page 4 of 4 Because heparin disappears rapidly from the circulation, the dose of protamine sulfate required also decreases rapidly with the time elapsed following intravenous injection of heparin. 1 mg protamine for every 100 units dalteparin. 4.2 Dose and method of administration Adults: Protamine sulfate should be administered by slow intravenous injection over a period of about 10 minutes.
