Protamin Sulphate

Protamin Sulphate is a medicine which is used in the treatment of heparin overdose. It neutralizes the anti-blood clotting effect of heparin and stops excessive bleeding. Protamin Sulphate is generally administered by a healthcare professional. You should not self administer this medicine. Inform your doctor if you have undergone heart surgery, have had a vasectomy, have diabetes, have received protamine insulin, or allergic to fish. Using of Protamin Sulphate can cause few side effects such as decreasing your blood pressure, slow heart rate, or reactions at the site of injection. It is important to monitor the clotting levels if you are receiving multiple doses or prolonged administration of protamine. Protamin Sulphate is used to counteract the anticoagulant effect of heparin and is used to stop bleeding in patients caused by heparin.

• Heparin overdose

Protamine sulfate, prepared from the sperm or mature testes of salmon or related species, is a heparin antagonist. It combines with heparin to form a stable inactive complex. Protamine sulfate is often used in the treatment of bleeding from severe heparin overdose and should not be used in minor overdose/bleeding as heparin withdrawal will usually correct itself within a few hr. For LMWH, protamine sulfate neutralises the anti-thrombin activity but only partly neutralises the anti-factor-Xa effect. When admin in the absence of heparin, protamine sulfate has an anticoagulant effect. Protamine is not useful for reversing the effects of oral anticoagulants.

Adult Dose: Intravenous Heparin overdosage Adult: Dosage depends on administered heparin dose, its route of admin, time elapsed since heparin admin, and blood coagulation studies. For heparin administered via IV inj: If only a few min have elapsed since admin, 1 mg for every 100 U of heparin administered; if 30-60 min have elapsed since admin, 0.5-0.75 mg for every 100 U of heparin; and if >2 hr have elapsed since admin, 0.25-0.375 mg for every 100 U of heparin. Doses to be given via inj at 8 hr has elapsed since admin, infuse 0.5 mg for every 1 mg of enoxaparin administered. For dalteparin: 1 mg for every 100 anti-Xa U of dalteparin administered. If aPTT remains prolonged 2-4 hr after the 1st infusion, a 2nd infusion may be given.
