Asclera™ (
polidocanol) is a prescription medication used to treat
spider veins and reticular veins. It belongs to a class of drugs known as sclerosing agents. As with all medicines, it is probably possible to overdose on Asclera. The specific effects will vary, depending on a number of factors, including the
Asclera dosage and whether it was taken with any other medicines or substances.
It is important to understand that Asclera works by damaging the lining of the veins, causing the vein to be replaced by scar tissue. If too much Asclera is injected, there is a risk that the medication may leak out of the treated vein and into the surrounding tissue, perhaps causing damage, which could be severe.
If this occurs, you may need to see a specialist (such as a vascular surgeon) right away to help minimize the damage. Severe damage is especially likely if Asclera is accidentally injected into an artery instead of a vein.
As you can see, careful injection is absolutely critical. Therefore, the best way to minimize the chances of an Asclera overdose is to make sure your healthcare provider is properly qualified to perform sclerotherapy.
An Asclera overdose also increases the risk of dangerous allergic reactions. It is recommended that no more than 10 mL total (no matter what the strength) be injected per treatment session, and no more than 0.3 mL per treated vein. If you have extensive spider or reticular veins, you might need multiple treatment sessions.
