What is sclerotherapy?

Sclerotherapy is the injection of a solution called a sclerosant directly into the affected blood vessel using a fine needle. This solution irritates the lining of the vessel causing it to swell and stick together, the sealed vein is then disposed of by the body.

This isn't an immediate result and the vein fades slowly typically taking 8 weeks or more to disappear.

Usually 2 or 3 treatments are needed, but once successfully removed the results are permanent, however if new veins appear further treatments may be required.

What side effects can occur?

Complications are rare and the treatment has been around in some form since the 1920's. However occasionally some patients can develop darkening of the skin which may take up to 12 months to resolve.

Localised swelling, bruising and tenderness can also occur after treatment, however these symptoms are minor and resolve quickly.

What happens after treatment with sclerotherapy?

You will be required to wear strong support tights or stockings (these must be brought with you to your appointment) for up to 6 weeks. Failure to do so may compromise the effectiveness and ultimately the outcome of your treatment.

You may have redness and bruising in the treated area but this usually resolves within a week. We recommend taking arnica tablets for a week pre- and post treatment, also the use of aloe vera gels has been reported to help.

Do not undertake any vigorous or high impact exercise for 2 weeks following treatment.

Avoid taking aspirin and ibuprofen for a week post treatment.

Avoid sunbathing, saunas, solariums and hot baths for 2 weeks following treatment.

Do not fly for 4 weeks post treatment.

Please note that the affected area will look worse before it looks better this is normal, but should be considered when planning your treatment.
