Acts by irritation of the vein intimal endothelium and causes thrombosis formation leading to occlusion of the injected vein
Use: Labeled Indications
Varicose veins: Treatment of small, uncomplicated varicose veins of the lower extremities that show simple dilation with competent valves.
Hypersensitivity to sodium tetradecyl sulfate or any component of the formulation; acute superficial thrombophlebitis; valvular or deep vein incompetence; phlebitis migrans; acute cellulitis; acute infections; allergic conditions; bedridden patients; patients with uncontrolled systemic disease such as diabetes, toxic hyperthyroidism, tuberculosis, asthma, neoplasm, sepsis, blood dyscrasias, and acute respiratory or skin diseases; huge superficial veins with wide open communications to deeper veins; allergic conditions; varicosities caused by abdominal and pelvic tumors (unless tumor has been removed)
Canadian labeling: Additional contraindications (not in US labeling): Recent superficial or deep thrombophlebitis (6 months to 2 years); potential underlying arterial disease; renal or cardiac insufficiencies accompanied by venous stasis and dilatation; angina pectoris; hyperthyroidism
Sclerosing agent: IV: Note: The strength of solution required depends on size and degree of varicosity; in general, the 1% solution is used most often, with the 3% solution being reserved for larger varicosities.
Test dose: 0.5 mL followed by several hours of observation is recommended before larger doses are administered.
Usual dose: 0.5 to 2 mL (preferred maximum: 1 mL) in each vein; maximum dose: 10 mL per treatment session of the 3% solution (Dietzek 2007)
The following concentrations have been recommended upon size of affected vein (Dietzek 2007):
Vessel diameter <1 mm: 0.1% to 0.3% concentration
Vessel diameter 1 to 3 mm: 0.5% to 1% concentration
Vessel diameter 4 to 6 mm: 1% to 2% concentration
Branch varicosities: 2% to 3% concentration
