Uses

Sodium Tetradecyl Sulfate (STS) is a synthetic detergent that is primarily used as a sclerosing agent, particularly in the treatment of varicose veins and other malformations related to blood vessels. Below are some of the primary uses of Sodium Tetradecyl Sulfate-

  • During the sclerotherapy procedure, it is often used to treat leg varicose and spider veins (at concentrations between 0.1% and 3%). When injected directly into the vein, it damages the endothelium, the inner lining of the blood vessel. This leads to inflammatory destruction of the internal lining of the vein and thrombus formation eventually leading to sclerosis of the vein.
  • In some circumstances, STS may be administered off-label as a sclerotherapy for hemorrhoids.
  • Additionally, some lymphatic malformations, a kind of vascular aberration that impacts the lymphatic system, are treated using STS.
  • In individuals with Ehlers-Danlos syndrome, it is sometimes used to treat the stabilization of joints that frequently dislocate.

Side effects

Side effects associated with the use of Sodium tetradecyl sulfate are –

  • Pain, redness, and swelling at the injection site
  • Bruising around the injection site
  • Mild headache
  • Nausea & vomiting
  • Allergic reactions
  • Pain or swelling in one or both legs
  • Chest pain, sudden cough, wheezing, rapid breathing, fast heart rate
