Asclera® is used in a procedure called sclerotherapy to treat spider veins. Asclera® is injected into the vein and works by damaging the cells lining the inside of blood vessel. This causes the vein to scar and collapse, forcing blood to reroute through healthier veins. The collapsed vein is reabsorbed into local tissue and eventually fades.
A typical sclerotherapy session lasts 15 to 45 minutes. Following treatment compression stockings or support hose should be worn continuously for 2-3 days and for 2-3 weeks during the day time. After sclerotherapy, treated veins tend to fade within a few weeks, although occasionally it may take up to a month to see the full results. In some instances, several sclerotherapy treatments may be needed.
