Varithena is the only FDA-approved injectable foam used to treat spider veins, varicose veins, and venous reflux disease. It's the brand name of polidocanol, a sclerosing agent that's injected into malfunctioning veins, including great saphenous veins (GSV) and accessory saphenous veins above and below the knee, to gently close them and redistribute blood to healthier, stronger veins.
Venus reflux disease occurs when veins don't properly allow blood flow back to your heart, sometimes causing blood to flow in reverse and pool in the legs.Â
Treating this disorder improves symptoms like heaviness, achiness, swelling, throbbing leg pain, and itchiness.Â
A canister of Varithena contains a mixture of oxygen and carbon dioxide, which are easily soluble in blood. It's released as a microfoam with small, dense, uniform bubbles, which its manufacturer claims withstand breaking down for longer than other sclerotherapy treatments.Â
This staying power gives it a high success rate in collapsing the vein walls of the diseased vein and redirecting blood flow to healthy blood vessels.
