The number of treatments is defined according to the severity of the case, the response to treatment and the results desired by the patient. Each person requires a different number of treatments depending on their situation. During your first treatment, the nurse will be able to give you an estimate of the number of sessions to plan following her assessment.


What is sclerotherapy?

This is the treatment of superficial varicose veins by injection. The term sclerotherapy comes from the Latin "sclerus" meaning scar. Sclerotherapy is a treatment that therefore causes scarring of the injected varicose vein. This treatment consists of injecting drugs into the incompetent veins to interrupt their functioning. The veins will close and eventually deteriorate.

How is the treatment going?

The sclerotherapy session takes place in the clinic, with a valid individual prescription only. The document to be completed by your doctor before your appointment is attached below. The session is carried out by authorized clinical nurses who have received specific training in this area.

Sclerotherapy does not require anesthesia or incision, as the injections are made with fine needles. A sclerosing product is injected into the incompetent veins (varicose veins, reticular veins and telangiectasias). The concentration of the product is chosen according to the caliber of the vein to be treated. After disinfecting the skin, the nurse injects the sclerosing product into different parts of the vein to be treated. You can resume activities the same day. Wearing compression stockings is generally recommended after the session.


  • Bruises may appear following the treatment. These will go away after about 2-3 weeks.

  • Hard bumps may appear as a result of the treatment. If they do not diminish after 4 to 5 weeks, let us know.

  • You may feel a little discomfort following the treatment. However, if you experience excessive pain, contact us.

  • Avoid heat (very hot bath, spa, sauna, etc.) for a period of 2 weeks after the treatment.

  • If you feel any discomfort, you can take Tylenol/acetaminophen (1g) if you are not allergic to it.

  • If you experience burning, tingling and/or itching, you can apply cold compresses to the sensitive areas.

  • To optimize the treatment received, wearing support stockings is strongly suggested for 2 weeks from morning to evening. Remove the stockings at night and for your shower.

  • A follow-up visit is recommended 2-3 weeks after your treatment.

  • You can practice your sports activities without any problem. On the other hand, avoid any impact sport with your legs for a period of 2 weeks.

What are the results ?

Above all aesthetic, sclerotherapy also reduces the symptoms associated with venous disorders, such as pain and burning sensation in the legs, since by removing varicose veins, blood circulation in the operational veins is improved. It thus makes it possible to stabilize the superficial venous disease. Several sessions are often necessary for optimum results. However, since varicose disease is a progressive disease, varicose veins can recur.

What are the risks ?

Sclerotherapy is a technique with very little risk. Besides bruises which are common and temporary (2-3 weeks), inflammatory hyperpigmentation (brownish spots) or small ulcerations may appear in a minority of cases. These side effects subside after a few weeks to a few months depending on the case.


No sclerotherapy treatment will be carried out without the evaluation of the nurse and receipt of the prescription signed by your doctor.
