Imagine looking down at your legs and noticing thin, blue or purple lines snaking under your skin. For many people, these are spider veins or small varicose veins. They can make you feel self-conscious, and sometimes they ache or itch. But what if a simple injection could make them disappear? This is the promise of sclerotherapy, a treatment that has helped many people regain confidence in their legs. Read ahead to know more about it.
What Is Sclerotherapy?

Sclerotherapy is a medical treatment for spider veins and small varicose veins. Dr Nirav Panchani, Interventional Cardiologist, Aadicura Hospitals, Vadodara, explains, “Sclerotherapy is where a liquid is injected directly from a fine needle into the varicose veins. This liquid irritates the wall of the veins so that it collapses. This stops the flow of blood, and the body absorbs that vein.”
During the procedure, you usually lie down with your legs slightly raised. The doctor cleans the area and uses a very fine needle to inject a special solution into the problem vein. This solution, called a sclerosant, irritates the vein’s lining, causing it to swell and stick together. Over time, the vein turns into scar tissue and fades away.

How Does Sclerotherapy Work?![3 - 2025-06-20T133254.120]( "Sclerotherapy for veins")
The main goal of sclerotherapy is to close off the faulty vein. Once the vein is closed, blood naturally reroutes through healthier veins. The treated vein is slowly absorbed by the body and eventually disappears. Most people see improvement within a few weeks, but sometimes it can take a month or more for full results. Some veins may need more than one treatment session.
Dr Panchani adds, “But this treatment is only for spider veins and small varicose veins. For large and bulging veins, laser or surgery is a better option. But keep in mind that sclerotherapy is not safe for everyone. For example, if you have a pregnancy, blood clot history, or an allergy, then consulting a specialist first is a must.”

The procedure is quick, usually taking about 15 to 45 minutes. You might feel a small pinch from the needle and a mild burning or cramping sensation as the solution is injected. After the procedure, your doctor may massage the area and apply a compression pad or stocking. Walking is encouraged to help prevent blood clots. Most people can return to their normal activities the same day, but you may need to wear compression stockings for a few days.

Sclerotherapy is not for everyone. Dr Panchani warns, “If you are pregnant, have a history of blood clots, or have allergies to the injection solution, it’s important to talk to your doctor first.” Also, sclerotherapy is not suitable for large, bulging veins. In those cases, other treatments like laser therapy or surgery may be better options.
Are There Any Risks?
Sclerotherapy is generally safe, but like any medical procedure, it has risks. Possible side effects include bruising, redness, or small brown spots at the injection site. Rarely, more serious problems like blood clots or allergic reactions can occur. Varicose veins are not just a cosmetic issue. If ignored, they can lead to more serious health problems like deep vein thrombosis (DVT) and skin ulcers. Treating them early can help prevent complications and improve your quality of life.
