Nearly all cases of spider veins—the result of genetics, pregnancy, obesity, hormonal changes or prolonged standing (not leg crossing, that’s a myth)—can be cleared with in-office sclerotherapy. Specifically, Dr. Kirman uses FDA-approved Asclera®. These medication injections safely ‘shut down’ the blood vessels, causing them to tighten up and disappear. The good news is uncomplicated spider veins don’t pose any real threat to your health and your body doesn’t need these veins for circulation, so they can be easily and safely eliminated.

Sclerotherapy is used to treat the following conditions:

• Spider veins

• Small varicose veins (usually 4mm or less)

What To Expect

A sclerotherapy injection takes just minutes to administer. However, it can result in temporary bruising, and veins may get darker before they disappear, which makes this an ideal cold weather treatment since you can hide under clothes without having to turn down any pool party invitations.


Most patients take a Tylenol® at least an hour before the vein treatment to help cut down the sting from the needle, but many say it’s less painful than laser hair removal or even waxing.


Some veins may sting while others won’t hurt at all during the vein treatment. Asclera®, which quickly works its way through the veins, can leave an itching feeling for a few minutes.


Your legs will be wrapped tightly with Ace bandages and you’ll want to sleep in support hose at night for a few days following the treatment to reduce swelling and keep the veins compressed. Asclera® therapy typically requires from three to five sessions, about once a month. 

Things To Consider

•Sclerotherapy is not suitable for if you are pregnant or breast-feeding.

•If you have more serious blood clots or DVT (deep vein thrombosis), alternative treatment will be necessary.

 • Side effects often include swelling, stinging and bruising.

•In rare cases, it’s possible for a treated vein to reopen and consequently reappear.


Q. Will it hurt?

A. Sclerotherapy involves needles and no anesthesia. It will hurt a little, but it’s perfectly tolerable.

Q. What is the recovery time?

A. You can go home right away, but will need to wear compression dressings for several days after your vein treatment. You should also avoid strenuous workouts for a good two weeks and stay out of the sun.

Q. Will I experience any scarring? 

A. Typically not. More common side effects are itching, redness and bruising, which should fade and disappear in a matter of days.

Q. How long will my results last?

A. After completing your session, or course of sessions, treated veins shouldn’t return, however new ones can appear as you get older so consider multiple visits to our Bay Area office in Walnut Creek.
