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.
