Sodium tetradecyl sulfate (STS), sold under the brand name Sotradecol, is a medication used to treat varicose veins, esophageal varices, and spider veins.[1][2] It is used during a procedure known as sclerotherapy by injection into a vein.[2]

Common side effects include pain, redness, swelling, increased pigmentation, and skin breakdown.[1] Serious side effects may include pulmonary embolism, stroke, and anaphylaxis.[1] It is an anionic surfactant and detergent which results in inflammation, blood clot formation, and scarring of the vein into which it is injected.[2]

Sodium tetradecyl sulfate was approved for medical use in the United States in 1946.[2] It is relatively low in cost.[1] In the United States 5 doses costs about 330 USD as of 2021.[3] In the United Kingdom this amount costs the NHS about £34.[4]

Medical uses

It is occasionally used for the treatment of stabilisation of joints that regularly dislocate, particularly in patients with Ehlers-Danlos syndrome.[5]

Dosage

Up to 2 mL may be given at easy site of injection.[2] A small initial dose is recommended before further doses to rule out a significant reaction.[2]

In the UK, Ireland, Italy, Australia, New Zealand and South Africa, it is sold in concentrations of 0.2%, 0.5%, 1.0%, and 3%.[6]

Synthesis

It may be prepared by the aldol condensation of methyl isobutyl ketone and 2-ethylhexanal (which is itself formed by the aldol self-concensation of butyraldehyde), followed by sulfonation of the resulting alcohol.
