Sclerotherapy with Asclera

If you are unhappy about the appearance of visible veins beneath your skin, you may be a candidate for sclerotherapy. This minimally invasive procedure is one of the most effective treatments for eliminating unsightly spider veins and smaller varicose veins. In our New York practice, we perform sclerotherapy using Asclera®, a unique injectable solution that yields excellent results.

How sclerotherapy with Asclera works

During a sclerotherapy treatment, the patient will be injected Asclera into the unwanted vein, which damages the cells that line the inside of the vein. Over time this causes the blood vessel to clot and then close completely. Eventually the damaged vein will be replaced with healthy tissue and will no longer be visible beneath the skin’s surface.

Sclerotherapy has been in use since the 1930s and is considered to be the gold standard in treating smaller veins. Over the years, doctors have experimented with a variety of injectable solutions with varying results. Asclera, which was approved by the FDA in 2010, has proven to be one of the most effective solutions for sclerotherapy. In fact, nearly 90% of our New York patients report that they are happy with the results provided by Asclera!

what to expect after your treatment

Sclerotherapy is a minimally invasive procedure with a quick recovery period, but certain precautions need to be taken to ensure optimal results. This includes the use of compression garments or bandages for several days after your treatment. The amount of time required varies based upon the number and size of veins that are being treated. We ask that sclerotherapy patients follow these post-treatment instructions:


Asclera is an excellent choice for many of our NYC patients. It can be used to treat the following types of visible veins:

It is approved for use in patients who are at least 18 years old. Anyone who has a known allergy to polidocanol or acute thromboembolic disease should not undergo treatment with Asclera. In this case, another solution or vein treatment may be recommended. Sclerotherapy should also be avoided if you are pregnant or nursing.

Results of sclerotherapy

The full results of your treatment will be seen within 4 – 8 weeks. If veins are still visible after 4 weeks, you may be recommended to have another sclerotherapy treatment session. It is normal for patients to require 2 – 3 session to completely clear unwanted veins using sclerotherapy.
