What is Sclerotherapy?
Sclerotherapy is a minimally invasive medical procedure used for varicose vein removal and to eliminate spider veins. During the procedure, a solution called a sclerosant is injected into the affected veins, causing them to collapse and eventually fade away. For a more detailed description, read our past sclerotherapy blog here.
How Many Sclerotherapy Sessions Are Needed?
The number of sessions required for the spider vein laser treatment varies depending on the severity and number of veins being treated. Typically, 2-4 sessions are recommended, spaced 3-4 weeks apart. Some patients may see results after just one session, while others may need more.
What Are the Sclerotherapy Results: Before and After?
Patients often notice a noticeable improvement in the appearance of their veins after treatment. Before and after photos typically show reduced visibility of spider and varicose veins, with the treated areas looking smoother and healthier.
How Effective is Sclerotherapy for Varicose Veins?
Sclerotherapy is highly effective for treating spider veins and varicose veins. It is considered one of the most effective non-surgical treatments available, with a success rate of 75%- 90%. Most patients experience a significant reduction in symptoms and cosmetic improvement.
What Can I Expect During a Sclerotherapy Session?
The procedure is quick, usually taking between 15-60 minutes. When performed by a skilled AMARA specialist at a varicose vein clinic, the procedure typically takes about 20 to 30 minutes and does not require hospitalization or anesthesia. It involves injecting the sclerosant into the veins using a fine needle. There is no downtime, and patients can resume normal activities immediately after the session.
Is Sclerotherapy Painful?
Most patients tolerate sclerotherapy well and report minimal discomfort. The procedure does not typically require anesthesia, but a topical numbing agent can be used if needed. When performed by a skilled AMARA specialist, patients may feel a slight prick, but the procedure is generally painless.
What are the Side Effects of Sclerotherapy?
Common side effects include bruising, itching, swelling, skin discoloration, and redness around the injection site. These side effects are usually temporary and resolve within a few days to weeks. Serious complications are rare.
What Should I Avoid After Sclerotherapy?
For best results after sclerotherapy, it’s important to follow certain guidelines. Patients should wear compression stockings as advised by their healthcare provider. They should also avoid strenuous exercise for a few days and hot baths or saunas to support proper healing.
Are There Alternatives to Sclerotherapy?
Yes, there are alternatives to sclerotherapy for vein treatment, including laser therapy, radiofrequency ablation, and vein stripping surgery. Each option has its own benefits and considerations, so it’s important to discuss these with a qualified specialist to determine the best treatment for your condition.
Does Sclerotherapy Work for Everyone?
While sclerotherapy is compatible with most patients, there is no absolute guarantee of success for everyone. Under 10% of patients may experience poor to fair outcomes, where veins do not completely disappear after six treatments. In rare cases, the condition of the veins may worsen following treatment.

Frequently Asked Questions
