Asclera® (polidocanol) is prescription medicine used in sclerotherapy or the treatment of uncomplicated spider veins (very small varicose veins ≤ 1 mm in diameter) and reticular veins (small varicose veins 1 to 3 mm in diameter) by injecting a solution, typically sodium tetradecyl sulfate (STS) directly into the vein.
Asclera is a sclerosing agent that 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; cellular debris and platelets cause the blood vessel to clot. Over time, the clotted vein will be replaced with healthy tissue and fade from view.
87% of patients treated with Asclera were satisfied or very satisfied with the results of their treatment after just 12 weeks as compared to only 64% satisfaction reported by patients treated with STS.
Asclera sessions take approximately 15 to 45 minutes. Typically, one injection is administered per inch and multiple injections are administered per session. Compression stockings or support hose should be worn continuously for 2-3 days after treatment and for 2-3 weeks during the day time. If repeat sessions are required, they are usually done 1 to 2 weeks apart.
