Asclera® (polidocanol) is a prescription medicine that is injected into the affected vein during sclerotherapy therapy. It is administered by a healthcare provider to treat two types of veins:
- 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.
Asclera® works by damaging the endothelium, the cells lining the inside of blood vessels. This causes blood platelets and cellular debris to attach to the lining of the vessels; eventually, cellular debris and platelets cause the blood vessel to clot and close. Over time, the clotted vein will be replaced with healthy tissue.
