Polidocanol
Asclera (polidocanol) is an injectable prescription medication used for sclerotherapy to treat visible spider veins and small varicose veins. It works as a sclerosing agent that is administered directly into affected veins, causing them to collapse and eventually be absorbed by the body. This treatment is typically performed by healthcare professionals in clinical settings.

Asclera is indicated for the treatment of spider veins (telangiectasias) and small varicose veins (varices) of the lower extremities. It is used when these cosmetic or symptomatic vein conditions require medical intervention.
Asclera is a sclerosing agent that works by damaging the endothelium (inner lining) of the target blood vessel when injected. This causes the vein to collapse, fibrin to form, and the vessel to eventually be reabsorbed by the body, redirecting blood flow to healthier veins.
Asclera should only be administered by qualified healthcare professionals experienced in sclerotherapy techniques. It is not suitable for patients with known allergies to polidocanol, those with acute thromboembolic diseases, or individuals with certain vascular conditions. Common side effects may include injection site reactions, bruising, and discoloration. Patients should follow post-procedure care instructions including compression stockings as directed.
