Sclerotherapy is one of the best methods of treating spider veins. Have you noticed blue, purple, or red lines on your skin? These damaged veins are called spider veins and come in the form of a thin line, webs, or branches on the surface of the legs or face. There are neither harmful nor painful, but they do stand out against one’s features and draw unwanted attention.


What Is Sclerotherapy?

Sclerotherapy is a non-surgical medical procedure that is used to eliminate spider veins and smaller varicose veins. It is also used to treat lymph vessel disorders.

It involves the injection of a salt-based solution called a sclerosant into a vein in order to completely destroy it. Sclerosant irritates the vessels and causes them to swell. It damages the endothelium – the innermost lining of the vessel – and results in a clot that blocks blood circulation through the vein.

Besides spider veins, sclerotherapy is most often used for varicose veins, which come about due to chronic venous insufficiency, which swells and bulges the veins. It is caused by weak vein walls, which lead to weak vein valves.

Sclerotherapy is also used to treat hydroceles, malformed lymph vessels, and hemorrhoids.

Am I a Good Candidate?

You can consider this treatment if you have prominent veins that are causing you physical issues or embarrassment. The veins may cause pain and form a rash near them. The skin around them may be patchy or dry, and the affected leg may feel heavy or sore.

If small varicose veins and spider veins are causing difficulties, then schedule a consultation immediately. Your vein specialist will consider sclerotherapy as a treatment option after assessing your problematic vein or lymph vessel.


You will receive a set of instructions to be followed prior to the treatment, which includes the following:

  • Avoid certain medications as suggested by your doctor, including various over-the-counter drugs and dietary supplements. Make sure to tell your doctor about any medications or supplements you are currently taking.
  • Do not apply any lotion or oil to the treatment area before the procedure.
  • You may be asked to take antibiotics before the treatment.
  • Avoid taking anti-inflammatory drugs at least three days before the treatment.


What Should You Expect from This Treatment?

The treatment is incredibly simple and very convenient, and it does not require any anesthesia. During the treatment, the areas surrounding the affected veins are first cleaned using a cleanser or antiseptic.

A small needle is then inserted into the vein and the irritating solution is injected. You may feel a burning sensation or even tingling. Some people may feel nothing at all. The treated area is then slowly and gently massaged, which prevents the blood from re-entering the vein. To collapse the veins completely, you may need follow-up treatments.

After Sclerotherapy

Recovery after sclerotherapy is relatively easy. You may need to wear a compression sock or bandage in the treated area for a few days or as recommended by your doctor. It is recommended that you stay active after the procedure to avoid a blood clot.
