Sclerotherapy is a widely used, minimally invasive treatment for spider veins and small varicose veins. For first-time patients, it can feel unfamiliar—even intimidating. Yet knowing what to expect during a sclerotherapy session can significantly ease anxiety, enhance cooperation during the procedure, and help ensure optimal outcomes. This guide provides a detailed, medically grounded overview for anyone preparing for their first treatment.

How Sclerotherapy Works and Why It’s Recommended
At its core, sclerotherapy involves injecting a specially formulated solution directly into the affected veins. This solution—commonly a saline or chemical sclerosant—irritates the lining of the vein, causing it to collapse. Over time, the treated vein is absorbed by the body and blood is rerouted through healthier vessels.
The procedure is particularly effective for small varicose veins and spider veins that are not causing significant discomfort but are visible or potentially progressing. Sclerotherapy is not cosmetic fluff—it is a proven medical procedure with decades of clinical success behind it.
Patients who benefit most include those with:
- Small-to-medium varicose or spider veins
- No history of blood clotting disorders
- Realistic expectations about gradual, rather than immediate, cosmetic results
While outcomes vary based on vein size and location, most individuals see noticeable improvement within several weeks to a few months.
Preparing for Your First Sclerotherapy Appointment
Before your first sclerotherapy session, your vascular specialist will perform a thorough consultation. This usually involves reviewing your medical history, performing a physical examination, and possibly using ultrasound to map your venous system. You’ll be asked to avoid certain skincare products (like lotions or creams) on your legs for 24 hours prior and to wear loose-fitting clothing to your appointment.
Certain medications, including blood thinners, may need to be paused under physician guidance. Hydration, moderate movement, and avoiding shaving the treated area are often part of pre-session advice.
What Actually Happens During the Procedure
A typical session lasts between 30 to 45 minutes, depending on the number and size of veins being treated. Patients remain awake and alert throughout.
After positioning you comfortably, your specialist will cleanse the skin and begin injecting the sclerosant solution using a very fine needle. You might feel a mild burning or cramping sensation at the injection site, but discomfort is usually brief and tolerable.
Each treated vein receives a small injection, after which compression—via bandages or stockings—is applied. In many cases, treated areas look red or raised immediately after the procedure, but these effects subside quickly.
Importantly, Sclerotherapy does not require anesthesia, and there’s no need for incisions or stitches.
Post-Procedure Expectations and Aftercare
Once the procedure is complete, most patients are encouraged to walk immediately to promote circulation. However, strenuous exercise, hot baths, and direct sun exposure should be avoided for at least 48 hours. Compression stockings should typically be worn for one to two weeks following treatment, depending on your specialist’s instructions.
Bruising, slight swelling, or darkening of the treated veins can occur, but these effects are temporary. It’s also common to require more than one session to achieve full cosmetic or medical improvement, especially for larger clusters of veins.
Following your doctor’s guidance closely during the recovery period is key to optimizing results.
When to Follow Up and What Long-Term Results to Expect
While some veins may disappear almost entirely after a single session, others may require repeat treatments, spaced several weeks apart. The total number of sessions needed will depend on the severity and number of veins treated, your body’s healing response, and any underlying venous insufficiency.
Regular follow-up visits help monitor progress and adjust the treatment plan if needed. Patients are also encouraged to discuss lifestyle modifications to prevent future vein issues—like improving posture, exercising regularly, and elevating the legs when sitting for long periods.
