Sclerotherapy for Spider Veins & Small Varicose Veins
Spider veins and small varicose veins can be frustrating—whether you’re bothered by how they look or how your legs feel at the end of the day. Sclerotherapy is a minimally invasive, in-office treatment that can reduce the appearance of these veins and, in some cases, relieve associated discomfort.
At Coastal Vascular Center, our vascular specialists take a personalized approach. We’ll evaluate your veins, discuss your goals, and recommend the most appropriate treatment plan for both appearance and long-term vein health.

Sclerotherapy isn’t “one treatment for everyone.” During your visit, we’ll confirm what type of veins you have and whether there are signs of underlying vein disease that should be addressed first.
If sclerotherapy isn’t the best option—such as when veins are larger or symptoms suggest venous reflux—we may recommend other vein treatments as part of a complete care plan.
What is Sclerotherapy?
Sclerotherapy is a minimally invasive treatment used to reduce or eliminate spider veins and treat select small varicose veins. A solution is injected into the targeted vein using a very small needle. The solution irritates the vein lining, causing it to seal closed over time so the vein can gradually fade.
How Sclerotherapy Works
Sclerotherapy involves injecting a specialized chemical solution directly into the problematic vein. This solution irritates the lining of the vein, causing it to scar and collapse. Blood is then rerouted through healthier veins, and over time, the treated vein is reabsorbed by the body and gradually fades from view, leaving your skin clearer and smoother. The procedure is performed in a doctor’s office and does not require anesthesia, making it a convenient outpatient option.
What Does Sclerotherapy Treat? (Including Varicose Veins)
- Varicose veins: Twisted and enlarged veins, often appearing blue or purple, that can cause discomfort and cosmetic concerns.
- Spider veins: A mild form of varicose veins that appear as small, thin red or blue lines, typically on the legs or face.
Who Can Benefit
Did you know that approximately 55% of women and 40-45% of men experience vein-related issues at some point in their lives? Varicose veins, in particular, can be highly visible and may cause embarrassment or discomfort for many individuals. Sclerotherapy is especially effective for small veins such as spider veins and small varicose veins.
During your consultation, we’ll review your medical history, examine the veins you’d like treated, and discuss what kind of results are realistic for your situation.
Expected Results
Many patients notice improvement over time, but results aren’t instant.
- Spider veins often begin fading in 3–6 weeks
- Larger veins can take longer—sometimes a few months
- Multiple sessions may be recommended depending on the number and size of veins treated
We’ll also review what to do after treatment to help support the best possible outcome.

Benefits and Risks of Sclerotherapy
The procedure improves the appearance of veins, and treated vessels typically show significant improvement. Sclerotherapy typically results in the elimination of 50 to 80 percent of the injected veins (treated vessels) after treatment. Treated veins tend to fade within a few weeks, but it may take up to two months to see full results. Varicose veins that go away with treatment generally do not come back, but new ones can appear over time, and ignoring them can raise concerns about the dangers of leaving varicose veins untreated.
Key Benefits
- Minimally Invasive: Unlike some surgical options, sclerotherapy does not require anesthesia and involves only the injection of a solution, reducing risk and recovery time
- Convenient: performed in-office with minimal downtime
- Effective for spider veins: and many small varicose veins
- Cosmetic improvement: many patients experience significant improvement in the appearance of treated veins.
- Pain Relief: Provides relief for those who experience aching or discomfort from varicose veins.
- Improved Venous Health: Redirects blood to healthier veins, improving overall venous circulation and reducing the risk of further vein issues associated with chronic venous insufficiency and venous reflux disease.
Potential Risks and Side Effects
Sclerotherapy is considered safe for most patients, but side effects and risks can occur. These may include:
- Temporary redness, tenderness, or bruising at injection sites
- Temporary skin discoloration near treated veins
- Mild inflammation or swelling
- Rare allergic reaction to the solution
- Rare clotting complications that may require additional treatment
- Infection risk is low, but possible with any injection
- Very rarely, nerve damage may occur in the treatment area, usually temporarily.
- Occasionally, tiny air bubbles can inadvertently enter the bloodstream during sclerotherapy. This may cause symptoms such as nausea, headaches, coughing, and, in rare cases, visual disturbances.
What to Expect After Treatment
- Recovery: Most patients can return to normal activities on the same day, although strenuous exercise should be avoided for a few days.
- Results: Treated veins typically fade within a few weeks, but it may take up to two months to see full results.
- Follow-Up: A follow-up visit is usually scheduled to assess the effectiveness of the treatment and decide if more sessions are needed.
The decision to undergo sclerotherapy should be based on a thorough consultation with a vascular specialist who can assess your condition and medical history. For many individuals, the benefits of sclerotherapy significantly outweigh the risks, particularly when performed by experienced professionals at reputable centers such as the Coastal Vascular Center. Here, the focus on advanced techniques and patient safety can further mitigate treatment-related risks, ensuring a positive outcome.
What to Expect During and After Treatment
Consultation and Preparation
Before treatment, you’ll meet with a vein specialist who will evaluate your veins and symptoms. In some cases, an ultrasound may be recommended to assess underlying vein function.
You’ll also review your medical history and medications with your provider. If you take blood thinners or supplements, follow your provider’s instructions—do not stop medications unless you’re specifically told to.
The Procedure (Step-by-Step)
Sclerotherapy is typically straightforward:
- The treatment area is cleaned
- A small needle is used to inject the solution into targeted veins
- You may feel mild stinging or cramping briefly
- Compression may be applied after treatment
Appointments often take 15–45 minutes, depending on how many veins are treated.
After Treatment
Most patients return to normal daily activities the same day. You may be advised to:
- Walk regularly after treatment
- Wear compression stockings for a period of time
- Avoid strenuous exercise for a short time
- Avoid sun exposure on treated areas to reduce the risk of discoloration
Follow-Up
A follow-up visit may be scheduled to check progress and determine whether additional sessions would help you reach your goals.
Who Is a Candidate for Sclerotherapy?
Ideal Candidates Often Include People Who:
- Have Spider or Small Varicose Veins: The primary candidates are those with visible, small—to medium-sized spider or varicose veins. These veins often appear twisted and bulging and can be blue, red, or purple.
- Are in Good General Health: Candidates should be in overall good health without serious underlying conditions that could complicate the procedure or recovery.
- Have Realistic Expectations: It is important to understand the potential outcomes and limitations of sclerotherapy. While the procedure can significantly improve the appearance of treated veins, it is not a guarantee against new vein problems in the future.
- Are Not Pregnant or Nursing: Sclerotherapy is not recommended for women who are currently pregnant or breastfeeding. Pregnancy can exacerbate vein problems, and it’s best to wait until after pregnancy and nursing to assess the true extent of vein issues.
- Do Not Have a History of Blood Clotting Issues: If you have a history of blood clotting disorders or a previous deep vein thrombosis (DVT), you may not be a suitable candidate. A vascular specialist needs to evaluate your risks.
- Have Discomfort or Symptoms from Varicose Veins: Those experiencing aching, swelling, burning, night cramps or other discomforts from varicose veins may find relief from sclerotherapy.
Who May Not Be a Good Fit
Sclerotherapy may not be recommended for everyone. Your provider will review this with you, but it may not be ideal for people who:
- Individuals with Severe Varicose Veins: Patients with large varicose veins may require alternative treatments such as endovenous thermal ablation or surgery.
- Mobility-Impaired Individuals: Patients who cannot walk or move around easily may not be good candidates because movement post-procedure is important for recovery and circulation.
- Those with Certain Medical Conditions: People with heart conditions, circulatory disorders, or those currently fighting an infection may be discouraged from sclerotherapy.
Next Steps for Potential Candidates
If you believe you might be a candidate for sclerotherapy, the next step is to schedule a consultation with a qualified vascular specialist. During the consultation, the specialist will:
- Evaluate the severity and type of vein issues you have.
- Review your medical history.
- Discuss your treatment goals and what to expect from the procedure.
- Explain any preparatory steps and post-treatment care.
Remember that the eligibility for sclerotherapy is individual and can only be accurately determined by a healthcare professional. If you are considering sclerotherapy, ensure you seek advice from a reputable vein specialist who can guide you through the decision-making process with your safety and well-being as the top priority.

Understanding the Sclerotherapy Procedure: What Happens During Treatment?
Sclerotherapy is a minimally invasive, in-office procedure used to treat spider veins and certain small varicose veins. It typically does not require anesthesia. During treatment, a vascular specialist injects a solution into the targeted vein using a very small needle. The vein gradually closes, blood flow reroutes to healthier veins, and the treated vein fades over time.
Some veins respond best to a specific technique or solution (including foam in certain cases). Your provider will recommend the approach that fits your vein pattern and goals.
Before treatment, you’ll meet with a vein specialist to evaluate your veins and discuss your symptoms and goals. This visit may include a physical exam and, in some cases, an ultrasound to assess vein function—especially if you have larger varicose veins, swelling, or other symptoms.
To help your appointment go smoothly:
- Wear loose, comfortable clothing
- Let your provider know about all medications and supplements you take
- Follow any pre-visit instructions you’re given (including guidance on blood thinners—do not stop medications unless you’re specifically instructed)
The Procedure: Step-by-Step
While every patient is different, most sclerotherapy visits follow a simple process:
- Cleaning: The treatment area is cleaned to reduce infection risk.
- Injection: A small needle is used to inject the solution into targeted veins. You may feel mild stinging or brief cramping.
- Compression: Compression may be applied after injections to support healing and improve results.
- Duration: Most sessions take about 15–45 minutes, depending on how many veins are treated.
What to Expect Afterward
Most patients return to normal daily activities the same day. After treatment, you may be advised to:
- Walk regularly (movement helps support circulation)
- Wear compression stockings for a period of time
- Avoid strenuous exercise for a short time
- Avoid sun exposure on treated areas (or use sunscreen) to reduce the risk of discoloration
Follow-Up and Results
Results appear gradually. Spider veins often begin fading in 3–6 weeks, while larger veins can take longer. Some patients need multiple sessions for best results, especially when treating clusters of veins.
A follow-up visit may be recommended to evaluate progress and determine whether additional treatment would help you reach your goals.
