Polidocanol Injection


What is Polidocanol used for?


  • Polidocanol is a medication that is used for the treatment of varicose veins. It scars (scleroses) the veins, thereby reducing pain and swelling.
  • It is also commonly used to treated tendonitis and tenosynovitis (inflammation of the tendons).
  • In an attempt to heal the body of the tendonosis, new blood vessels and nerves (neovessels) grow into the diseased tendon, producing pain.
  • A polidocanol injection involves the use of an ultrasound machine which will demonstrate the presence of these neovessels, which are then injected with Polidocanol. .


Prior to the Procedure

  • All blood thinning products (except aspirin) must be stopped prior to your procedure. You will be advised by letter when to stop taking these medications at the time that your admission date is arranged.
  • You are able to take your other regular medications with a sip of water on the morning of your procedure.
  • If you are an insulin dependent diabetic you will always be at the beginning of the list. Please bring your insulin with you and it will be given to you following your procedure.
