Polidocanol is a local anaesthetic and antipruritic component of ointments and bath additives.
The substance is also used as a sclerosant, an irritant injected to treat varicose veins leading to fibrosis inside varicose veins and occlusion the lumen of the vessel.
This helps to reduce varicosity.
Polidocanol injections for the treatment of
- Uncomplicated spider veins (very small varicose veins < 1 mm in diameter)
- Uncomplicated small varicose veins (1 to 3 mm in diameter) known as reticular veins
Polidocanol works by damaging the cell lining of blood vessels, causing them to close and eventually be replaced by other types of tissue.
Recently, Polidocanol has been reported to be used in tennis elbow.
