Sclerotherapy is a medical procedure used to treat varicose veins and spider veins. It involves injecting a solution directly into the affected veins. The solution irritates the lining of the blood vessel, causing it to swell and stick together. Over time, the vessel turns into scar tissue that fades from view.

This procedure is commonly used for cosmetic purposes to improve the appearance of spider veins, which are small, damaged veins that can appear on the surface of the legs or face. Sclerotherapy can also help alleviate symptoms associated with varicose veins, such as aching, swelling, burning, and night cramps. Multiple sessions may be required.

During a sclerotherapy session, here's what you can generally expect:

  • Consultation: Your healthcare provider will begin by discussing your medical history and assessing your veins to determine if sclerotherapy is appropriate for you. They will explain the procedure, discuss potential risks and benefits, and answer any questions you may have.
  • Preparation: You will be asked to wear loose, comfortable clothing and refrain from applying lotion or oil to your legs on the day of the procedure. Our nurse may also recommend avoiding certain medications, such as blood thinners, prior to treatment. Ensure you bring your compression stockings/socks with you, be well hydrated to ensure the optimal results. Minimum 2L recommended to drink within 24 hours of treatment.
  • Positioning: You'll be asked to lie down on a treatment table, and your legs will be elevated to facilitate access to the veins being treated.
  • Cleaning: The skin over the targeted veins will be cleaned thoroughly with an antiseptic solution to reduce the risk of infection.
  • Injection: Using a fine needle, our healthcare provider will inject a sclerosing solution directly into the affected veins. The solution irritates the lining of the vein, causing it to collapse and eventually fade from view.
  • Monitoring: After each injection, our provider will apply gentle pressure to the treated area and may massage the area to distribute the sclerosing solution evenly.
  • Multiple Injections: Depending on the extent of your vein issues, multiple sessions may be necessary to treat all affected veins. Our nurse will work systematically to address each area of concern.
  • Post-Treatment Care: Once the injections are complete, your legs may be bandaged or wrapped in compression dressings to help promote healing and reduce swelling. Our nurse will provide specific instructions on how to care for your legs following the procedure, including wearing compression stockings and avoiding certain activities.
  • Follow-Up: You will be scheduled for a follow-up appointment to assess the results of the treatment and determine if additional sessions are needed.
  • Results: It may take several weeks to months for you to see the full results of sclerotherapy, as the treated veins gradually fade from view. Multiple treatment sessions may be required to achieve optimal results.

Throughout the procedure, your healthcare provider will prioritize your comfort and safety, and they will be available to address any concerns you may have.


The number of sclerotherapy treatments needed varies depending on the size and number of veins being treated, as well as individual response to the procedure. Generally, multiple sessions spaced several weeks apart are required to achieve optimal results.

For spider veins, smaller veins near the surface of the skin, significant improvement can often be seen after just one session. However, additional treatments may be necessary to fully eliminate them.

For larger varicose veins, it may take several sessions to achieve satisfactory results. The exact number of treatments needed will be determined by your healthcare provider based on your specific condition and response to treatment.

It's essential to follow your healthcare provider's recommendations regarding the number and frequency of sclerotherapy treatments to achieve the best possible outcome.

Wearing compression stockings after sclerotherapy is important for several reasons:

  • Promoting Healing: Compression stockings help promote healing by applying pressure to the treated veins, which helps reduce swelling and inflammation. This pressure also encourages the walls of the treated veins to stick together, aiding in the closure of the vessels.
  • Preventing Blood Clots: Compression stockings help prevent the formation of blood clots by improving blood circulation in the legs. After sclerotherapy, there is a risk of blood clots forming in the treated veins. Compression stockings reduce this risk by facilitating blood flow and preventing blood from pooling in the veins.
  • Minimizing Bruising and Discoloration: Wearing compression stockings can help minimize bruising and discoloration that may occur after sclerotherapy by reducing blood leakage from the treated veins into the surrounding tissue.
  • Enhancing Treatment Results: Compression stockings help maintain the pressure on the treated veins, which can improve the effectiveness of the sclerotherapy treatment. They can also help prevent the recurrence of treated veins by supporting the surrounding veins.

Overall, wearing compression stockings after sclerotherapy is an essential part of the post-treatment care regimen to promote healing, reduce complications, and improve treatment outcomes. It's important to follow your healthcare provider's recommendations regarding the duration and type of compression stockings to wear after sclerotherapy.

The timing for flying after sclerotherapy can vary depending on several factors, including the extent of the treatment, your overall health, and your risk factors for developing complications such as blood clots. However, many healthcare providers recommend waiting a minimum of 2 weeks before flying after sclerotherapy. Long road trips should also be avoided or discussed with our nurse.

Flying involves sitting for an extended period, which can increase the risk of blood clots forming in the legs, especially after a procedure like sclerotherapy. Additionally, the changes in cabin pressure and altitude during a flight can potentially affect circulation and increase the risk of complications.

Here are some general guidelines to consider:

  • Consult Your Healthcare Provider: Before planning any travel, including flying, after sclerotherapy, it's essential to consult your healthcare provider. They can assess your individual situation and provide personalized recommendations based on your specific condition and treatment.
  • Wait for Healing: It's important to allow sufficient time for the treated veins to heal before subjecting them to the potential stresses of air travel. This typically involves waiting at least 1-2 weeks, but your healthcare provider may recommend a longer period depending on your circumstances.
  • Take Precautions During Travel: When you do fly after sclerotherapy, there are some precautions you can take to reduce the risk of complications. These may include wearing compression stockings during the flight, staying hydrated, and periodically moving and stretching your legs during the journey.
  • Consider Shorter Flights Initially: If possible, consider taking shorter flights initially before attempting longer flights. This can help you gauge how well you tolerate flying after sclerotherapy and allow you to make adjustments as needed for future travel plans.

Ultimately, the decision on when it's safe to fly after sclerotherapy should be made in consultation with your healthcare provider, who can provide personalized guidance based on your individual circumstances.
