Does micro-sclerotherapy have any side effects?

Although micro-sclerotherapy is a safe method of treatment, undesirable side effects cannot be ruled out completely like with any medical procedure or taking medicine. Small areas of bleeding in the skin, haematomas, and temporary discolouration may occur around the site of the treated spider veins, although these usually resolve soon after treatment. The insertion of the fine needle can obviously be felt as a short prick, which may last for a moment, but 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 spider veins are not dangerous and can easily be dealt with by your doctor. The chronic nature of the condition does mean that spider veins may appear again in the treated area after some time, even after successful treatment with any method. The new spider veins can also be treated if necessary.

These reactions are the most common side effects of micro-sclerotherapy. Systemic allergies or circulatory reactions are, for example, very rare.

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.
