Sclerotherapy

Sclerotherapy in Sarasota & Bradenton

Spider Veins, Treated. An In-Office Procedure That Takes Less Time Than Lunch.

Sclerotherapy is the most widely used and well-validated treatment for spider veins and small varicose veins. A sclerosant solution is injected directly into the affected vein, causing the vein wall to swell, stick together, and seal closed. The closed vein is gradually absorbed by the body and fades over several weeks to months.

At Vascular Wellness Institute, sclerotherapy is performed in the office without the need for anesthesia or downtime. Most patients return to their normal activities the same day.

Why We Look Before We Treat

Sometimes spider veins are just spider veins. Sometimes they are the surface sign of a larger vein underneath that is not working properly — and that is the reason they come back after treatment.

Every patient here is evaluated by a board-certified vascular surgeon, and when the pattern suggests something deeper we perform an ultrasound to look. If the veins you can see are being fed by a vein you cannot, treating only the surface means treating it again in a year, and then again after that.

That is not an upsell. Sometimes the answer is that sclerotherapy is exactly right and nothing further is needed. Sometimes it is that sclerotherapy alone would be the wrong choice, and we will tell you so before you spend money on it.

What Sclerotherapy Treats

  • Spider veins (telangiectasias) — small red, purple, or blue veins visible at the skin surface
  • Reticular veins — slightly larger blue-green feeder veins under the skin
  • Small varicose veins remaining after endovenous ablation
  • Residual varicosities after other vein procedures


Sclerotherapy treats the veins you can see. It does not treat the larger vein underneath that is usually causing them. When ultrasound shows reflux in a saphenous vein, that vein is closed first — with radiofrequency ablation (RFA), Varithena® foam, or VenaSeal™ adhesive, depending on the anatomy — and sclerotherapy is then used to clear the surface veins that remain. Injecting surface veins without addressing the source is the most common reason spider vein treatment disappoints.

What to Expect

Using a very fine needle, a small amount of sclerosant solution is injected into each targeted vein. Most patients describe a mild stinging or burning sensation that passes within seconds. Multiple veins are typically treated in a single session. The session takes 15-30 minutes. Compression stockings are worn after treatment. Patients are instructed to walk immediately and avoid prolonged sitting, sun exposure on the treated areas, and strenuous exercise for 48 to 72 hours.

How Many Sessions Will I Need?

Most patients need more than one. Spider veins clear gradually, and each session treats the veins that are visible at that time — as those fade, smaller ones underneath often become apparent. Two to three sessions spaced several weeks apart is typical, though it depends on how extensive the veins are.

Results appear over weeks rather than immediately. Treated veins fade progressively, and the final result is usually apparent two to three months after the last session.

Cosmetic sclerotherapy is generally not covered by insurance and is paid out of pocket. When spider veins are accompanied by symptoms — aching, heaviness, swelling — or when an ultrasound identifies an underlying problem, treatment may be covered. We check before you commit to anything.

Frequently Asked Questions

  • How many sclerotherapy sessions will I need? +

    The number of sessions depends on the extent of your spider veins. Many patients see significant improvement after two to four sessions. Each session can address multiple veins. Touch-up treatments are common over time — new spider veins can develop with age and additional treatment may be needed.

  • How long does it take to see results from sclerotherapy? +

    Spider veins typically begin to fade within three to six weeks. Larger reticular veins may take three to four months to fully resolve. Immediately after injection, veins may look slightly worse before they begin to improve — this is normal.

  • Does sclerotherapy work for large varicose veins? +

    Sclerotherapy is most effective for spider veins and small to medium varicose veins. Large varicose veins caused by saphenous vein reflux require endovenous ablation first to eliminate the underlying cause. Sclerotherapy is then used to treat residual surface veins. Attempting to inject large varicosities without treating the underlying reflux typically produces poor results.

  • Is sclerotherapy covered by insurance? +

    Sclerotherapy for cosmetic spider veins is generally not covered by insurance. When performed for symptomatic varicose veins — documented pain, swelling, or skin changes related to venous disease — coverage may apply. Our staff will review your situation and advise you on coverage before scheduling.

  • Are there any restrictions after sclerotherapy? +

    Avoid sun exposure to treated areas for two weeks to minimize pigmentation. Wear compression stockings as directed. Avoid hot baths, saunas, or hot tubs for 48 hours. Walking is encouraged; prolonged sitting or standing should be avoided for the first 48 hours. Most normal activities can be resumed the same day.
