Sclerotherapy in Singapore: What is It And is It Right for You?
Varicose Veins Treatment
Have you heard of sclerotherapy, but are unsure whether it’s the best course of action for treating your spider or varicose veins?
Continue reading to learn everything there is to know about sclerotherapy in Singapore, including its process, costs, and alternatives.
WHAT is it
What is Sclerotherapy and How Does it Work?
Sclerotherapy is a minimally invasive treatment which leaves a tiny puncture mark at the injection site. A solution is injected into varicose or spider veins, causing them to collapse and fade over time. Foam and liquid types target different vein sizes, with suitability depending on your vein condition, health status, and treatment goals—assessed by a vascular specialist.
How Sclerotherapy Works
The sclerotherapy process begins with your vascular specialist identifying the specific veins requiring treatment through visual examination and ultrasound imaging. A very fine needle is used to inject a special solution (sclerosing agent) directly into the targeted vein. Once injected, the sclerosing agent irritates the vein’s inner walls, causing them to swell and stick together. This immediately blocks blood flow through the treated vein, forcing circulation to reroute through healthier vessels nearby.
The body’s natural healing mechanisms then take over, gradually breaking down and absorbing the sealed vein tissue over several weeks to months. This process is completely normal and safe, as these problematic veins were already functioning poorly and not contributing to healthy circulation.
Modern sclerotherapy techniques have evolved considerably from early methods, incorporating advanced imaging guidance and refined sclerosing solutions to maximise effectiveness whilst minimising discomfort and side effects.
Types of Sclerotherapy: Foam vs Liquid Sclerosants
There are two main types of sclerosants: liquid and foam.
- Liquid sclerotherapy is usually used for smaller veins (i.e. spider veins and small varicose veins), using solutions like sodium tetradecyl sulphate or polidocanol in various concentrations. These liquid agents work well for surface veins and smaller vessels.
- Foam sclerotherapy tends to be more effective in treating larger varicose veins as this foam has better contact with vein walls and displaces blood more effectively. Ultrasound-guided foam sclerotherapy enables treatment of veins that aren’t visible on the surface, allowing specialists to target deeper varicose veins with precision. This technique has expanded the range of conditions treatable with sclerotherapy rather than requiring surgical intervention.
Your vascular specialist will determine the most appropriate type of sclerosant based on your specific vein anatomy, size, and treatment goals during your consultation.
Who Is a Good Candidate for Sclerotherapy?
Ideal candidates for sclerotherapy are those who:
- Have spider veins or small to medium-sized varicose veins
- Are generally in good health, not pregnant or breastfeeding
- Do not have a history of blood clots, certain autoimmune conditions, or severe peripheral artery disease
Your suitability for sclerotherapy can only be properly determined through professional medical evaluation, including assessment of your overall health and detailed examination of your vein condition.
PROCEDURE
Sclerotherapy Procedure & Recovery
Here’s what to expect before, during, and after a typical sclerotherapy treatment session.
What Happens During Treatment
The procedure usually takes 15 to 45 minutes, depending on the number of veins being treated.
Your sclerotherapy appointment begins with a thorough review of your medical history and examination of the veins to be treated. The specialist uses a very fine needle to inject the sclerosing agent directly into each targeted vein. You may feel a mild stinging or cramping sensation during injection, but most patients find this quite tolerable.
Each injection typically takes just a few seconds, and multiple veins can be treated during a single session. The total number of injections depends on the extent of your vein problem and the treatment plan developed specifically for you. After completing the injections, compression stockings or bandages are applied to the treated areas. You’ll be able to walk immediately after treatment, which is actually encouraged to promote healthy circulation.
At the Vascular and Interventional Clinic
The actual sclerotherapy procedure is performed in our clinic as an outpatient treatment, requiring no general anaesthesia or hospital admission.
Most patients can return to work the next day, though some activity restrictions apply during the initial recovery period.
What to Expect
What to Expect During Sclerotherapy Recovery
The first 24-48 hours after sclerotherapy require some activity modifications to optimise healing.
Walking is encouraged, but avoid strenuous exercise, hot baths, saunas, and prolonged sun exposure during this initial period.
Wearing prescribed compression stockings is important for proper healing and best results. These stockings help maintain pressure on treated veins and support healthy blood flow during the recovery process.
Some patients experience mild discomfort, bruising, or swelling in treated areas, which is normal and typically resolves within a few days to weeks. Over-the-counter pain relievers can help manage any discomfort.
When to Expect Results
Initial results from sclerotherapy become visible within 2-4 weeks as treated veins begin to fade, but full results typically take 2-3 months to develop completely as the body gradually absorbs the sealed vein tissue.
Spider veins often respond more quickly than larger varicose veins, with some patients noticing improvement within the first week. However, the healing process varies between individuals.
Some veins may require multiple treatment sessions to achieve optimal results, particularly larger or more stubborn veins. Your specialist will assess your progress and determine if additional treatments are needed during follow-up appointments.
The final cosmetic result continues to improve for up to six months after treatment as any residual discolouration fades and the skin returns to its normal appearance
How Long Do Results Last after Sclerotherapy
Successfully treated veins are permanently closed and will not return, as the sclerosing process destroys the vein wall structure completely. This represents one of the key advantages of sclerotherapy over temporary treatments.
However, sclerotherapy doesn’t prevent new veins from developing over time. Factors like genetics, hormonal changes, pregnancy, weight gain, or prolonged standing can contribute to new vein formation in different areas.
RISKS
Sclerotherapy Risks and Side Effects: What You Need to Know
Sclerotherapy techniques have a good safety profile when performed by a qualified vascular specialist. But, like any medical procedure, it carries some risks and potential side effects.
Most side effects are mild and temporary, resolving without intervention as your body heals from the treatment. However, being aware of potential complications enables you to follow post-treatment instructions carefully and seek appropriate care if needed.
Common Side Effects: Bruising, Swelling, and Discolouration
- Bruising at injection sites affects nearly all patients to some degree and represents a normal response to the needle insertion and sclerosing agent. This bruising typically peaks within the first week and gradually fades over 2-4 weeks.
- Post-treatment swelling in the treated leg is common, particularly after treating larger veins or multiple areas in one session. This swelling usually subsides within a few days and responds well to leg elevation and compression therapy.
- Temporary brown discolouration (hyperpigmentation) may occur as trapped blood and iron deposits are gradually absorbed. This discolouration is usually mild and fades within 6-12 months, though it can occasionally persist longer.
- Red raised areas or hives near injection sites can occur in patients sensitive to the sclerosing agent but typically resolve within hours to days with or without antihistamine treatment.
Rare but Serious Complications to Watch For After Sclerotherapy
- Deep vein thrombosis (blood clots in deep veins) is an extremely rare complication, occurring in very few patients.
- Allergic reactions to sclerosing agents are uncommon, but can range from mild skin reactions to severe anaphylaxis.
- Skin ulceration at injection sites is rare but can occur if sclerosing agent leaks into surrounding tissues.
- Nerve injury causing numbness or tingling is extremely rare with current techniques, but can occur if sclerosing agent affects nearby nerves.
How to Minimise Sclerotherapy Risks
Choosing an experienced vascular specialist who performs sclerotherapy regularly reduces your risk of complications and ensures proper technique and patient selection.
Following all pre-treatment instructions, including medication adjustments and avoiding certain supplements that increase bleeding risk, helps prepare your body for optimal healing.
Strict adherence to post-treatment guidelines, particularly wearing compression stockings and avoiding prohibited activities, substantially reduces complication risks and improves outcomes.
Attending all scheduled follow-up appointments allows early detection and management of any complications, ensuring the best possible results from your treatment.
COSTS
Sclerotherapy Costs in Singapore
Sclerotherapy pricing in Singapore varies based on several factors including the extent of treatment needed, type of sclerosing agent used, number of sessions required, and whether you choose public or private healthcare facilities.
Understanding the cost structure helps you budget appropriately for treatment and compare options between different providers. Many patients find sclerotherapy cost-effective compared to other vein treatments, particularly for spider veins and smaller varicose veins.
The total investment in sclerotherapy should be considered alongside the long-term results and potential need for future treatments, as successfully treated veins are permanently eliminated.
Insurance coverage and Medisave eligibility depend on whether your condition is considered medically necessary or purely cosmetic, which varies based on symptoms and documentation.
Cost of Sclerotherapy
The cost of sclerotherapy in Singapore can vary depending on the severity of your vein condition, the number of sessions required, and whether ultrasound guidance or foam is used.
According to the Ministry of Health’s fee benchmarks, the surgeon’s fee for sclerotherapy typically ranges from $1,900 to $4,300. This makes it one of the more affordable options compared to surgical or laser-based treatments for varicose veins. The table below outlines how sclerotherapy compares to other common vein treatments in terms of estimated surgeon’s fees.

Public Hospital vs. Private Clinic Costs for Varicose Veins Treatment
Public hospital sclerotherapy services typically offer lower costs but may have longer waiting times and less flexibility in scheduling appointments. Treatment quality remains high, as these facilities employ qualified vascular specialists.
Private clinics generally charge higher fees but offer shorter waiting times, more personalised service, and often more flexible scheduling options. Some private clinics also offer additional services like advanced imaging or combination treatments.
The choice between public and private care often depends on your urgency for treatment, budget considerations, and personal preferences regarding healthcare delivery.
Both public and private providers in Singapore provide high standards of care, so the decision often comes down to cost, convenience, and individual preferences.
Insurance & Medisave Coverage
Medisave coverage for sclerotherapy is available when the treatment is deemed medically necessary. Conditions like painful varicose veins with documented symptoms may qualify for partial coverage.
Private insurance coverage varies widely between policies and providers. Some comprehensive health insurance plans cover medically necessary vein treatments, whilst others exclude these procedures entirely or have specific limitations.
To qualify for insurance coverage, you typically need documentation of symptoms like pain, swelling, skin changes, or functional impairment rather than purely cosmetic concerns.
Pre-approval from insurance providers is recommended before proceeding with treatment to understand your coverage.
ALTERNATIVES
Sclerotherapy Alternatives
Not everyone is best suited for sclerotherapy, and understanding alternative treatments helps ensure you receive the most appropriate care for your specific condition.
Different vein treatments work better for different types of veins, symptoms, and patient circumstances. Your vascular specialist can help determine which approach offers the best balance of effectiveness, safety, and cost for your situation. Some patients benefit from combination treatments using multiple approaches to address different aspects of their vein problems comprehensively.
Sclerotherapy vs Laser Therapy: Pros and Cons
Laser therapy works well for very small spider veins and surface vessels, using focused light energy to heat and destroy targeted veins without injections. However, it’s generally less effective for larger veins and can be more painful than sclerotherapy.
Laser therapy may be preferred for patients with needle phobia or those who cannot tolerate sclerosing agents due to allergies. However, multiple laser sessions are often needed to achieve results comparable to sclerotherapy.
Cost considerations often favour sclerotherapy, as laser treatments typically require more sessions and can be more expensive overall despite lower individual session costs.
When Surgery Is Better Than Sclerotherapy
Large or complex varicose veins (>3-4mm diameter) with underlying venous insufficiency often respond better to surgical treatments like endovenous laser ablation, radiofrequency ablation, or surgical removal rather than sclerotherapy alone.
Patients with significant symptoms like severe pain, recurrent infections, skin ulcers, or bleeding from varicose veins typically need surgical intervention to address the underlying venous insufficiency effectively.
Your vascular specialist will use duplex ultrasound imaging to assess your vein anatomy and determine whether surgical treatments would provide better outcomes than sclerotherapy.
Combination Treatments for Optimal Results
Many patients achieve good results combining different treatment approaches, such as surgical treatment of large varicose veins followed by sclerotherapy for remaining spider veins or smaller vessels.
Endovenous procedures to treat underlying venous insufficiency can be combined with sclerotherapy to address surface veins, providing comprehensive treatment of the entire vein problem.
Sequential treatments allow specialists to address different aspects of vein problems systematically, starting with underlying issues and progressing to cosmetic concerns for better outcomes.
Combination approaches often provide better long-term results than single treatments alone, particularly for patients with complex vein problems or extensive disease.
FAQs about Sclerotherapy
Is sclerotherapy painful?
Most patients describe sclerotherapy as mildly uncomfortable rather than painful, comparing the sensation to a small pinprick followed by possible mild cramping or stinging that lasts just a few seconds per injection.
The fine needles used for sclerotherapy are much smaller than those used for typical injections or blood draws, minimising discomfort during the procedure.
Post-treatment discomfort is usually minimal and well-controlled with over-the-counter pain relievers like paracetamol or ibuprofen if needed.
How many sessions are needed for sclerotherapy?
The number of sclerotherapy sessions required varies based on the extent of your vein problem, size of veins being treated, and your individual response to treatment.
Spider veins often respond well to 1-2 sessions, whilst small varicose veins may require 3-4 sessions spaced 4-6 weeks apart to achieve complete clearance.
Each session can treat multiple veins, but there are limits to how much can be safely treated in one appointment. Your specialist will develop a treatment plan based on your specific needs.
Some patients achieve satisfactory results with fewer sessions, whilst others with complex vein problems may benefit from additional treatments for complete clearance.
Can veins return after sclerotherapy?
Successfully treated veins are permanently closed and cannot return, as the sclerotherapy process destroys the vein structure completely.
However, new veins can develop over time due to ongoing factors like genetics, hormonal changes, pregnancy, weight fluctuations, or occupational demands that contributed to your original vein problems.
The development of new veins typically occurs gradually over years rather than months, and these new veins can be treated with additional sclerotherapy if desired.
