Sclerotherapy Information Hampshire Uk


Excellent for:


  • Veins that can be seen but not felt


Good for:


  • Veins that can be felt but are protected by good valves


Poor for:


  • Varicose veins where the veins leak. These are better treated surgically 



How does sclerotherapy work?

A chemical called polidocanol is injected through a very fine needle into the vein. The polidocanol irritates the vein which is then removed by the body's white blood cells.

These fine veins are not needed by the body because the main flow of venous blood goes through the deep veins within the muscles of the leg.


What are the advantages of sclerotherapy over laser treatment of leg veins?

Research shows that it is a more comfortable and effective treatment for leg veins than laser treatment.


Is sclerotherapy safe?

Yes sclerotherapy is very safe in well trained hands.

Sclerotherapy should not be used on the face because there are communications between the veins on the face and the veins inside the brain.


Does sclerotherapy hurt?

No, the small pin-pricks that are involved in sclerotherapy are tolerated by all and are much more comfortable than laser treatment.


How should I prepare for sclerotherapy treatment?

There is no need to shave the leg or wax. Do not moisturise your legs on the day of treatment.


What is involved in sclerotherapy treatment?

The skin will be cleaned before treatment. You will then be given a series of injections with a very fine needle. Each injection clears a patch of veins the size of a 50p piece.


How will I look immediately after sclerotherapy treatment?

Afterwards, the site of each pin-prick will be covered with Micropore tape that can be removed after a few hours.


Is there any important sclerotherapy aftercare?

It is important that you go for a ten minute walk before driving away from the Clinic.

The treatments will be more effective if you wear medium support tights for 48 hours after each treatment.


How soon after the sclerotherapy injections will I notice an improvement?

The veins turn dark brown after treatment. The finer red veins will disappear after two to four weeks but the bigger blue ones can take several months to clear.


How many sclerotherapy treatments will I need?

Most people will need between 1-3 treatments given 4-6 weeks apart.

You can reduce the number of treatment sessions needed by exercising the legs for 20 minutes a day between each treatment session.


How long does sclerotherapy last?

The veins that have been cleared do not grow back. However, some people will grow more veins and need repeat treatment every few years.


Does sclerotherapy produce any side-effects?



  • Itching: You may experience mild itching for 1-2 days after treatment.
  • Brown lines: 10-15% of patients find that some veins do not clear within six weeks. Instead, these veins "remain" as mid-tan brown lines that last 6-12 months before clearing. Rarely, and usually around the ankle, the pigmentation is permanent.
  • Finer veins: Some patients develop leashes of very fine veins as a result of treatment. These will usually disappear during further treatment sessions.



  • Ulcers: A small ulcer may develop at the site of one of the injections. It heals over 4-8 weeks to leave a small white scar.
  • Allergies: Allergic reactions to the injections are serious but extremely rare. They only occur during the injection, which is why it is best to have the injections done in a well equipped clinic with medical help close at hand.
  • Superficial thrombophlebitis occurs in approximately 0.1% of patients. It is uncomfortable, lasts 2-4 weeks but is not dangerous.


Who shouldn't have sclerotherapy treatments?


  • Sclerotherapy should be avoided during pregnancy
  • Sclerotherapy should be approached with care if your ankles swell, or if you have had a deep vein thrombosis, a pulmonary embolus or a leg ulcer.
