What is sclerotherapy?

Sclerotherapy is a safe, injectable treatment to remove spider veins. A single session lasts up to 30 minutes, depending on the number of veins treated. The treatment involves injection of a sclerosant solution into the targeted spider veins. This solution is formulated to irritate the walls of the veins. After treatment, the targeted veins gradually collapse and disappear—leaving you with more even-toned legs.

Typically, a treated spider vein takes about three to six weeks to disappear. Larger ones may take a little longer. Blood that circulated through a treated vein is harmlessly redirected.

Spider Veins vs Varicose Veins

Do you have spider veins or varicose veins? Below are some distinguishing features of both types:

  • Spider veins, or telangiectasias, are normally 0.1 mm - 1 mm in diameter while varicose veins have a diameter of more than 1 mm.
  • Varicose veins can be red, blue or even the same colour as your skin. Spider veins tend to be blue or red.
  • Spider veins are located closer to the surface of your skin and look like thin jagged lines.
  • Varicose veins typically appear as bulging cords on the legs.

Sclerotherapy is able to treat spider veins.

A study published in the British Journal of Surgery reported that sclerotherapy is a safe treatment for veins, achieving successful results in 91% of cases with no serious complications reported.

Our Comprehensive Approach to Sclerotherapy

Sclerotherapy is designed to eliminate the spider veins that concern you. You'll meet with one of our board-certified dermatologists for an assessment to determine if this treatment is suitable for you.

We are able to treat your unsightly spider veins:

  • Without pain – patients have described the treatment as feeling like a mosquito bite.
  • Without surgery – the treatment only involves injections.
  • Without downtime – you can return to work or other daily activities immediately following a treatment (however, this does not include vigorous physical activity, which you’ll need to avoid for about 24 hours).

The treatment itself is well tolerated by our patients, therefore no anesthesia is typically required. A small needle is used to administer the sclerotherapy solution. You may feel a temporary tingling or slight burning sensation that quickly resolves.

Once the injections are complete, you’ll be able to return to your normal daily activities.

You may require up to four sessions scheduled about one month apart to achieve your desired results. Residual veins that are too small for sclerotherapy can subsequently be treated with Nd:YAG laser.

We recommend that sclerotherapy be performed during the fall, winter, and spring because the treated areas should not be exposed to the sun.

Common side effects include bruising and pigmentation.

Sclerotherapy FAQ

What is sclerotherapy?

Sclerotherapy is a treatment that involves the injection of a solution into a targeted spider vein. The solution collapses the veins walls, eliminating it.

How long does sclerotherapy last?

In more than half of patients, results are permanent after their treatment protocol is complete. Any veins that disappear are gone permanently, however new veins may appear in the targeted area.

What are the side effects and risks of sclerotherapy?

The following is a list of common side effects that may occur. These are all considered temporary.

  • itching
  • swelling, redness and bruising
  • tenderness
  • hyperpigmentation
  • before disappearing, treated veins may darken first

Other more serious risks that are extremely uncommon but would require immediate medical attention include the following:

  • allergic reaction
  • deep vein thrombosis (blood clot in leg)
  • ulceration at the injection site(s)
How do you get rid of trapped blood after sclerotherapy?

In some cases, a small pool of blood may become "trapped" in the targeted area. This blood is typically absorbed by your body over the weeks and months following your treatment. Trapped blood may also be drained to expedite the removal process.

How many treatments does it take to get rid of spider veins?

Typically, a treated spider vein takes about three to six weeks to disappear. Larger ones may take a little longer.  Multiple treatments are often required for significant improvement.  Small residual veins may be treated with Nd:YAG laser.

What should I avoid after sclerotherapy?

You'll be encouraged to walk around and perform gentle exercises following your treatment. High-impact and strenuous exercise should be avoided for about a week after treatment along with hot baths and showers. 

Is sclerotherapy covered by OHIP?

OHIP does not cover sclerotherapy. However, some private insurance providers may cover the treatment depending on your situation.
