How does Sclerotherapy work?


Sclerotherapy involves injecting a solution directly into unwanted spider or varicose veins. We use Asclera, a solution which causes less stinging at the injection site than other options. Once injected, Asclera damages the unwanted veins, causing blood to reroute through healthier vessels. The injected veins then collapse, are reabsorbed into the body and fade away, typically within six weeks. The length of the procedure depends on the number of veins you would like treated, but typically ranges from 15 to 30 minutes. There is a limit to how much solution can be injected at any one visit.

Is Sclerotherapy safe?

The FDA has approved Asclera to safely treat spider veins and small varicose veins. Sclerotherapy has an excellent safety profile. Like any surgical or non-surgical procedure, there are risks. Dr. Cox stresses the importance of finding a physician experienced in this procedure.

Sclerotherapy downtime

Sclerotherapy treatment is very well tolerated. We suggest that patients come dressed in loose clothing or wear shorts we provide for the treatment. There is no true downtime associated with sclerotherapy. Mild itching, tingling and burning are normal side effects that subside within minutes of treatment. You will be asked to wear support stockings for approximately two weeks following treatment to maintain vein compression and maximize results. After treatment, you may notice veins appearing darker before subsiding. This is a temporary and normal part of the healing process.

Sclerotherapy results

Sclerotherapy is clinically proven to reduce the appearance of spider veins and smaller varicose veins. Veins typically begin to fade three weeks after treatment, with full effect visible about six weeks post treatment. In addition to the cosmetic benefit, sclerotherapy also may improve aching, swelling, burning and cramping sometimes associated with varicose and spider veins. A series of treatments is required to produce results.
