What types of Veins is Asclera Approved For?
The injections are approved by the FDA for uncomplicated spider veins (very small varicose veins, less than 1mm in diameter) and reticular veins (uncomplicated small varicose veins that are 1 to 3 mm in diameter).
Can Asclera Be Used for Larger Veins?
The product is not FDA approved for treating larger veins (anything above 3mm in diameter). However, doctors suggest Asclera can be used ‘off-label’ by agitating the product into foam first before injecting the vessel. It is claimed the foam fills a larger space better than liquid. If you have concerns about larger veins, ask your doctor which treatment he/she recommends.
How long does Asclera take?
The treatment sessions themselves are relatively quick, taking only 15 to 45 minutes per session. Most patients require multiple injections, since one injection is used per inch. You may need several treatments depending on the size of the area you wish to treat. Most patients end up having two or three treatments initially then touch up treatments after one to five years to treat new veins. Following injections, the veins take several weeks before they disappear. Doctors suggest you have the treatment at least three months before you need vein free legs (whether it’s a formal occasion or looking to wear shorts or a bikini during the bathing season).
What Happens to the Veins After Asclera Treatment?
Once the injections are administered, the inner lining of the vessel is dissolved. After about 2 to 12 weeks, the vein will completely close. In time, the body ends up absorbing the scarred vein.
When can I return to Work after Asclera Injections?
The results vary among patients, however most people are able to return work and normal daily activities immediately. The manufacturer’s advice stipulates you should avoid heavy exercise, sunbathing, long plane flights, hot baths and saunas for two to three days following the treatment. If you’re unsure about your proposed activities, ask your doctor. Generally, you will be required to wear a compression bandage day and night for two to three days and throughout the day for the following 2-3 weeks. Your doctor will advise how long you need to wear the compression garment for, usually longer for reticular veins than spider veins.
What Are the Asclera Risks and Side Effects?
Asclera injections are made from a chemical call polidocanol which can cause severe allergic reactions including anaphylactic reactions which can be fatal. The severe cases occur where a larger volume (more than 3mL) is used. Advise your doctor if you are allergic to polidocanol, have an acute vein or blood clotting (thromboembolic) disease or are pregnant or nursing. You should not be treated with Asclera if any of these situations apply to you.
If the liquid leaks into the skin, then you may experience small ‘burns’ or ulcers. These heal in due course but may leave scarring. If the doctor accidentally injects an artery, this can cause severe necrosis, ischemia or gangrene. A practitioner may unintentionally inject outside the vein which can be painful. If this occurs, your doctor can provide local anaesthetic (without adrenalin) to alleviate discomfort.
Some adverse reactions have been found in clinical studies including hematoma, irritation, discoloration, pain, itching, warmth and clotting at the injection site and neovascularization.
