Updated 3/2017 -- all links (except to my own posts) removed as many no longer active.
The FDA recently (March 2010) approved Asclera (poliocanol) injection for the treatment of small spider veins (tiny varicose veins less than 1 millimeter in diameter) and reticular veins (those that are 1 to 3 millimeters in diameter).
Asclera is a detergent sclerosant and produces endothelial damage through interference with the cell's surface lipids.and acts by damaging the cell lining of blood vessels. This causes the blood vessel to close, and it is eventually replaced by other types of tissue.
Common adverse reactions to Asclera include leakage and collection of blood from damaged blood vessels at the injection site (hematoma), bruising, irritation, discoloration, and pain at the injection site.
Although they usually occur in the legs, varicose veins also can form in other parts of the body. Factors such as genetics, age, female gender, pregnancy, obesity, and prolonged periods of standing may increase the risk for varicose veins.
Asclera is distributed by BioForm Medical Inc. of Franksville, Wis., and manufactured by Chemische Fabrik Kreussler & Co. of Wiesbaden, Germany.
