Polidocanol

Asclera ® (polidocanol) is indicated to sclerose uncomplicated spider veins (varicose veins ≤1 mm in diameter) and uncomplicated reticular veins (varicose veins 1 to 3 mm in diameter) in the lower extremity. Asclera has not been studied in varicose veins more than 3 mm in diameter. Asclera (polidocanol) is a sclerosing agent indicated to sclerose uncomplicated spider veins (varicose veins ≤1 mm in diameter) and uncomplicated reticular veins (varicose veins 1 to 3 mm in diameter) in the lower extremity. Asclera has not been studied in varicose veins more than 3mm in diameter.

The active ingredient of Asclera is polidocanol. Polidocanol is a sclerosing agent that locally damages the endothelium of blood vessels. When injected intravenously, polidocanol induces endothelial damage. Platelets then aggregate at the site of damage and attach to the venous wall. Eventually, a dense network of platelets, cellular debris, and fibrin occludes the vessel. Finally, the occluded vein is replaced with connective fibrous tissue.

For intravenous use only. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if particulate matter is seen or if the contents of the vial are discolored or if the vial is damaged in any way. For spider veins (varicose veins ≤1 mm in diameter), use Asclera 0.5%. For reticular veins (varicose veins 1 to 3 mm in diameter), use Asclera 1%. Use 0.1 to 0.3 mL per injection and no more than 10 mL per session. Use a syringe (glass or plastic) with a fine needle (typically, 26- or 30-gauge). Insert the needle tangentially into the vein and inject the solution slowly while the needle is still in the vein. Apply only gentle pressure during injection to prevent vein rupture.

Asclera is contraindicated for patients with known allergy to polidocanol and patients with acute thromboembolic diseases. Known allergies to polidocanol. Patients with acute thromboembolic diseases.

Be prepared to treat anaphylaxis. Venous Thrombosis and Pulmonary Embolism. Arterial Embolism. Tissue ischemia and necrosis: Do not inject intra-arterially.

The most common adverse reactions occurring at least 3% more frequently than on placebo are mild local reactions at the site of injection.

No drug-drug interactions have been studied with Asclera.

Store at 15°C to 30°C, (59°F to 86°F).
