Treatment of varicose veins and spider veins (telangiectasias) associated with venous insufficiency. May be used when conservative treatments like compression stockings have not provided adequate relief.
Sotradecol is a detergent-based sclerosant that, when injected into the vein, damages the endothelium (inner lining) and causes protein denaturation. This leads to platelet aggregation, fibrin deposition, and eventual fibrosis of the vein, causing it to collapse and be absorbed.
Must be administered by a qualified healthcare professional experienced in sclerotherapy techniques. Contraindicated in patients with severe systemic illness, blood clotting disorders, or known hypersensitivity to the drug. Common side effects include temporary bruising, discoloration, and mild discomfort at the injection site. Patients typically require multiple treatment sessions for optimal results.
