Sodium Tetradecyl Sulfate (sodium tetradecyl sulfate)
Venosclerosing Agents Intravenous Vial (ML)
Last reviewed · Source: First Databank (FDB) drug data
Overview
Sodium tetradecyl sulfate (STS), an anionic surfactant and detergent, is used as a sclerosing agent.
Sodium tetradecyl sulfate (STS) is an anionic surfactant and detergent used as a sclerosing agent. The drug is commercially available in the US as a sterile, nonpyrogenic 1 or 3% solution. Each mL contains 10 mg (1%) or 30 mg (3%) of sodium tetradecyl sulfate with benzyl alcohol (0.02 mL) and dibasic sodium phosphate anhydrous in water for injection.
The solution has a pH of 7.9; monobasic sodium phosphate and/or sodium hydroxide are added for pH adjustment.
Following IV injection, sodium tetradecyl sulfate causes inflammation of the intima and thrombus formation, which usually occludes the target vein. Subsequent formation of fibrous tissue results in partial or complete vein obliteration; the effect on the vein may or may not be permanent.

Dosing
No dosing information is available for this tab.
Sodium tetradecyl sulfate is administered only by IV injection. Extravasation should be avoided. (See Administration Precautions under Cautions: Warnings/Precautions.)
Sodium tetradecyl sulfate is commercially available as a 1 or 3% solution in vials (containing a total of 20 or 60 mg, respectively, in each 2-mL vial). Although the drug has been administered as an endovenous foam or microfoam, these preparations are not commercially available in the US and extemporaneous preparation of sodium tetradecyl sulfate foam is not approved by the US Food and Drug Administration (FDA).
Unopened vials of sodium tetradecyl sulfate solution should be stored at 20-25degreesC.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Sodium tetradecyl sulfate solutions that have precipitated or are discolored should not be used.
Sodium tetradecyl sulfate is incompatible with heparin; therefore, the 2 drugs should not be mixed in the same syringe.
