Sclerotherapy FAQs

Do you use a local anesthetic?

Lidocaine is part of the solution that is injected into the vein, therefore the application of a topical anesthetic is not necessary. In addition, the needle used to inject the solution is very small, thereby reducing pain.

I am afraid of needles – can this be done under general anesthetic?

This procedure is not performed under anesthesia unless it is performed in combination with a surgical procedure such as vein ligation and stripping. An anesthetic cream may be applied to the area.

How long does the treatment take?
The treatment takes about 30 minutes, depending on how many veins are treated.

What kind of dressing is used?

A thigh-high compression stocking is applied to each treated leg after the injections and is worn for 1-3 weeks, depending on the size of the vessels being treated.

Will I be able to drive myself home?
Yes, you should be able to drive home after the treatment.

What are the side effects?
You may experience itching or raised, red areas or bruising at the injection site. This should disappear in a few days. Brown lines or spots may also appear at the injection site, which usually resolve after a few months. Larger injected veins may become lumpy or hard for several months before resolving.

Will I need to take time off work?
You may want to take a day off from work on the day you have your sclerotherapy treatment so that you can keep your legs elevated. It’s okay to return to work the next day. Exercise should be limited for a week to 10 days due to the necessity of wearing the compression stockings.
