Frequently asked questions

Are there any possible side effects of sclerotherapy?

Even though sclerotherapy (obliteration) is a safe method of treatment, it may have undesirable side effects like with any medical procedures or medicines that you take.

Small areas of bleeding in the skin, haematomas, and temporary discolouration may occur around the site of the treated varicose veins, although these usually resolve soon after treatment. The insertion of the fine needle can obviously be felt as a short prick. All in all, sclerotherapy is regarded as a particularly painless method in comparison with other treatments, such as laser therapy.
Local blood clots in the treated veins are not dangerous and can easily be dealt with by your doctor. The chronic nature of the condition does mean that varicose veins may again develop in the area treated, even after successful treatment no matter what method was used. These new varicose veins can be treated with sclerotherapy again whenever necessary.

The reactions mentioned here are the most common side effects of sclerotherapy. Systemic allergies or circulatory reactions are, for example, very rare. In contrast to surgical procedures, there is no risk of bleeding after treatment, scar formation from the incisions, or wounds that might not heal properly.

Before you start treatment, your doctor will explain the possible side effects to you – even though they are rare – and answer any questions you may have.
