Spider Vein Treatment by Sclerotherapy

Sclerotherapy is a form of spider vein treatment in which a sclerosing solution is injected into the blood vessel. The solution causes irritation and clotting in the vein, resulting in total collapse and eventual fading from view. Viewed by many as the most effective and time-tested of all spider vein treatment options, Sclerotherapy garners more results than topical treatments and induces less pain than laser therapies.


Patients being treated with Sclerotherapy will find that the process is a fairly simple outpatient procedure requiring no anesthesia. During treatment, the patient’s legs are elevated to reduce the amount of blood in each vessel. This makes the vessels more receptive to injection of the solution.

Each session may range in length from 5 to 45 minutes or more, depending on several factors including the range of the affected area receptiveness of the veins to treatment. Patients may need multiple treatments for permanent results, but potential candidates for Sclerotherapy should consult one of the skin care professionals at Island Dermatology for a more accurate assessment.

Side Effects

Most clinical procedures cause side effects and Sclerotherapy is no different. Most effects are minimal and include raised red areas at injection sites, brown spots or lines near the injection site (sometimes permanent), bruising, itching and swelling.

Rare side effects include the sudden onset of edema in the treated leg, small ulcers at the injection site and red streaking located near the groin. In the event of a rare side effect, one of the physicians at Island Dermatology should be contacted immediately for advice and treatment.


With as many as 50 to 80 percent of spider veins eliminated with each treatment, the prognosis is very good. Smaller veins will begin to disappear in three to six weeks and larger veins may take up to four months. Very few patients do not respond to Sclerotherapy for spider vein treatment, and must consider alternatives. For optimal results, consult a reputable dermatologist or skin care professional at Island Dermatology.
