Sclerotherapy FAQ

At Elmore Medical, we treat most spider veins with a treatment called sclerotherapy. Here are answers to ten common questions patients ask about this treatment method.

1. What is sclerotherapy?

Sclerotherapy is a common spider vein treatment that is also sometimes used in the treatment of varicose veins. It is the most effective procedure for spider veins and patients experience great results with one or more procedures. 

During the procedure, a sclerosing solution is injected into the affected veins. This solution causes an irritation to the inner lining of the vein, causing it to collapse. Over time, the treated vein fades away enough to not be seen.

2. Who can perform sclerotherapy?

The laws vary by state, but in California, only a licensed healthcare provider such as a Physician, Nurse Practitioner (NP), Physician Assistant (PA), or Registered Nurse (RN) is legally able to perform sclerotherapy. It is important to go to someone who has a great deal of experience to avoid complications.

Our sclerotherapy providers are some of the most sought-after in the Central Valley and have extensive experience in treating spider veins with this method.

3. How is the procedure administered?

After cleaning the affected area, the doctor will use a very fine needle to inject the sclerosant into the affected vein. Following the procedure, you will only be required to wear medical compression stockings for 1-2 weeks.

4. Is sclerotherapy painful?

Sclerotherapy is virtually painless. The needle is similar to an insulin needle or smaller. You may apply a topical numbing agent to eliminate the pricking sensation of the injection needle, but it is not required.

5. What areas of the body can be treated?

Sclerotherapy can be administered almost anywhere on the body, but the legs are the most common areas. 

6. Is sclerotherapy safe?

Sclerotherapy is considered safe for most patients. During your initial consultation, we will review your medical history and examine your veins to determine if you’re a good candidate for the procedure.

7. What results can I expect after sclerotherapy?

You can expect to see results within three to six weeks after your procedure. Some larger veins can take longer, and may require more than one treatment. After your procedure, the treated veins will not return.

8. What is the recovery time?

One of the incredible aspects of sclerotherapy is that it requires no downtime. You will be able to immediately return to most regular activities. Walking is strongly encouraged after treatment. However, aerobic or vigorous exercise should be avoided for several days after treatment.

9. What kind of aftercare is required?

Following sclerotherapy, we advise patients to wear compression garments to help speed up the healing process. We encourage patients to walk 20-30 minutes daily. Additional treatments may be needed based on the severity of your case. Additional treatment may be scheduled about 3 weeks apart.

10. What is the effectiveness of sclerotherapy?

According to the Mayo Clinic, the success rate of sclerotherapy is between 60 to 80 percent. For the 20 to 40 percent of cases where treatment doesn’t show full results after a single treatment, the procedure can be repeated to improve your results.
