Sodium tetradecyl sulfate (STS), sold under the brand name Sotradecol, is a medication used to treat varicose veins, esophageal varices, and spider veins. It is used during a procedure known as sclerotherapy by injection into a vein.

Common side effects include pain, redness, swelling, increased pigmentation, and skin breakdown. Serious side effects may include pulmonary embolism, stroke, and anaphylaxis. It is an anionic surfactant and detergent which results in inflammation, blood clot formation, and scarring of the vein into which it is injected.

Sodium tetradecyl sulfate was approved for medical use in the United States in 1946. It is relatively low in cost. In the United States 5 doses costs about 330 USD as of 2021. In the United Kingdom this amount costs the NHS about £34.
