Varicose veins and spider veins affect millions of people, causing both cosmetic concerns and physical discomfort like aching, heaviness, and swelling. Sclerotherapy offers an effective, minimally invasive solution that has successfully treated venous conditions for decades. This proven procedure involves injecting a special solution into problematic veins, causing them to close and eventually disappear, with success rates exceeding 80%.
How does Sclerotherapy work?
During sclerotherapy, a healthcare provider uses a fine needle to inject a sclerosing solution directly into the affected vein. This solution irritates the vein’s inner lining, causing the walls to swell and stick together, effectively sealing the vessel closed. Over the following weeks, the body naturally breaks down and absorbs the closed vein while rerouting blood flow through healthy veins. The treated veins gradually fade from view, typically showing improvement within 2-4 weeks.
Key Benefits
Sclerotherapy provides dramatic improvement in leg appearance, with unsightly varicose and spider veins fading and disappearing. Many patients experience significant relief from physical symptoms like aching, throbbing, and leg heaviness. Results are typically long-lasting, with successfully treated veins rarely recurring. The minimally invasive procedure requires no incisions or general anesthesia, allowing most patients to return to normal activities within 1-2 days.
Who Should Consider Treatment?
Ideal candidates include individuals with small to medium-sized varicose veins or spider veins causing cosmetic concerns or mild symptoms. The treatment works particularly well for spider veins and reticular veins. However, pregnant women should postpone treatment, and patients with blood clotting disorders, severe circulation problems, or those taking certain medications may need alternative approaches. A consultation with a vein specialist determines the best treatment plan.
Treatment Preparation

What to Expect?
Treatment sessions typically last 30-60 minutes with 15-30 small injections. Most patients describe mild pinprick sensations followed by brief cramping. Compression stockings are applied immediately after treatment, and light walking is encouraged. Initial darkening of treated veins is normal, with gradual fading beginning within 2-4 weeks. Multiple sessions may be needed, typically spaced 4-6 weeks apart.
Managing Side Effects
Common temporary effects include mild pain, itching, swelling, and bruising at injection sites. These typically resolve within days to weeks. Rare complications requiring medical attention include allergic reactions or signs of blood clots. Following post-treatment care instructions, wearing compression stockings as directed, and avoiding sun exposure help minimize risks and optimize results.
Frequently Asked Questions About Sclerotherapy
How many treatment sessions will I need?
Most patients require 2-4 treatment sessions to achieve optimal results, though this varies based on the extent of vein problems and individual response to treatment. Spider veins often respond well to fewer sessions, while larger varicose veins may require additional treatments. Sessions are typically spaced 4-6 weeks apart to allow proper healing.
Is sclerotherapy painful?
Most patients tolerate sclerotherapy very well, describing the sensation as similar to getting a vaccination. The injections cause brief, mild discomfort that quickly subsides. Some cramping or burning may occur as the solution takes effect, but this typically lasts only a few minutes. Over-the-counter pain medication can help manage any residual discomfort.
How long do results last?
Successfully treated veins rarely recur, making sclerotherapy results essentially permanent for those specific veins. However, the underlying tendency to develop varicose veins may remain, so new veins could potentially develop over time. Maintaining a healthy lifestyle, regular exercise, and proper weight can help prevent new vein problems.
Can I exercise after sclerotherapy?
Light walking is encouraged immediately after treatment to promote healthy circulation. However, strenuous exercise, heavy lifting, and high-impact activities should be avoided for 48-72 hours following treatment. Swimming and hot tubs should also be avoided for several days to prevent infection and optimize healing.
