Sclerotherapy: Before Your Procedure

Skip to the navigation

What is sclerotherapy?

Sclerotherapy is a treatment to get rid of varicose veins. A chemical called a sclerosant is injected into the varicose 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.

What happens before the procedure?

Having a procedure can be stressful. This information will help you understand what you can expect and how to safely prepare for your procedure.

Preparing for the procedure

  • Bring a list of questions to ask your doctors. It is important that you understand exactly what procedure is planned, the risks, benefits, and other options before your procedure.
  • Tell your doctors ALL the medicines and natural health products you take. Some of these can increase the risk of bleeding or interact with anesthesia. Your doctor will tell you which medicines to take or stop before your procedure.
  • If you take blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin, be sure to talk to your doctor. He or she will tell you if you should stop taking these medicines before your procedure. Make sure that you understand exactly what your doctor wants you to do.
  • You may need to stop taking certain medicines a week or more before your procedure, so talk to your doctor as soon as you can.
  • 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.

Taking care of yourself before the procedure

  • Build healthy habits into your life. Changes are best made several weeks before the procedure, since your body may react to sudden changes in your habits.
    • Stay as active as you can.
    • Eat a healthy diet.
    • Cut back or quit alcohol and tobacco.
  • If you have an advance care plan, let your doctor know. If you do not have one, you may want to prepare one so your doctor and loved ones know your health care wishes. Doctors recommend that everyone prepare these papers before a procedure, regardless of the type of procedure or condition.

What happens on the day of the procedure?

  • Follow the instructions exactly about when to stop eating and drinking, or your procedure may be cancelled. If your doctor has instructed you to take your medicines on the day of the procedure, please do so using only a sip of water.
  • Take a bath or shower before you come in for your procedure. Do not apply lotions, perfumes, deodorants, or nail polish.
  • Remove all jewellery, piercings, and contact lenses.
  • Leave your valuables at home.

At the doctor's office or clinic

  • Bring a picture ID.

Going home

  • You will be given more specific instructions about recovering from your procedure, including activity and when you may return to work.

When should you call your doctor?

  • You have questions or concerns.
  • You don't understand how to prepare for your procedure.
  • You become ill before the procedure (such as fever, flu, or a cold).
  • You need to reschedule or have changed your mind about having the procedure.
