Protamine (Protamine Sulfate) - Indications and Dosage

 
 



INDICATIONS AND USAGE

Protamine Sulfate Injection, USP is indicated in the treatment of heparin overdosage.

DOSAGE AND ADMINISTRATION

Each mg of protamine sulfate, calculated on the dried basis, neutralizes not less than 100 USP Heparin Units.

Protamine sulfate injection should be given by very slow intravenous injection over a 10-minute period in doses not to exceed 50 mg (see WARNINGS ).

Protamine sulfate is intended for injection without further dilution; however, if further dilution is desired, D5-W or normal saline may be used.  Diluted solutions should not be stored since they contain no preservative.

Protamine sulfate should not be mixed with other drugs without knowledge of their compatibility, because protamine sulfate has been shown to be incompatible with certain antibiotics, including several of the cephalosporins and penicillins.

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.  For example, if the protamine sulfate is administered 30 minutes after the heparin, one-half the usual dose may be sufficient.

The dosage of protamine sulfate should be guided by blood coagulation studies (see WARNINGS ).

Parenteral drug products should be visually inspected for particulate matter and discoloration prior to administration, whenever solution and container permit.
