Sclerotherapy: Before Your Procedure

What is sclerotherapy?

Sclerotherapy is a treatment to get rid of varicose veins and spider veins. A chemical called a sclerosant is injected into the vein. This causes the vein to close.

The procedure may cause some pain. The chemical that is injected may cause burning or cramping for a few minutes where the shot was given.

The procedure can take up to 30 minutes, depending on how many veins are treated and how big they are. You should be able to walk on your own after the treatment.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How do you prepare for the procedure?

Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.

Preparing for the procedure

  • Plan to wear loose, comfortable clothes. You may want to bring shorts to wear during the procedure.
  • Don't use any lotion on your legs before the procedure.
  • Be sure you have someone to take you home. Anesthesia and pain medicine will make it unsafe for you to drive or get home on your own.
  • Understand exactly what procedure is planned, along with the risks, benefits, and other options.
  • Tell your doctor ALL the medicines and natural health products you take. Some may increase the risk of problems during your procedure. Your doctor will tell you if you should stop taking any of them before the procedure and how soon to do it.
  • If you take aspirin or some other blood thinner, ask your doctor if you should stop taking it before your procedure. Make sure that you understand exactly what your doctor wants you to do. These medicines increase the risk of bleeding.
  • Make sure your doctor and the hospital have a copy of your advance care plan. If you don't have one, you may want to prepare one. It lets others know your health care wishes. It's a good thing to have before any type of surgery or procedure.

What happens on the day of the procedure?

  • Take a bath or shower before you come in for your procedure. Do not apply lotions, perfumes, deodorants, or nail polish.
  • Do not shave the surgical site yourself.
  • Take off all jewellery and piercings. And take out contact lenses, if you wear them.

At the doctor's office or clinic
