FDA-approved medications called Sotradecol® and Asclera® are used in our office for sclerotherapy. These medications are placed in the spider veins, causing the vein to seal shut. Once the vein is sealed, blood flows into healthier veins. The treated vein is absorbed and eventually disappears. Sotradecol® and Aslcera® give much better results and are far less painful than traditional hypertonic saline injections.
