Recently, the FDA approved a new drug for sclerotherapy. Sclerotherapy, involves injecting spider veins with a solution that will collapse the vein. The drug is called Asclera. The use of lasers has caused the number of sclerotherapy procedures to decrease. Some of the previous sclerosing agents caused discomfort with the injection or caused some skin discoloration afterwards. 

 

Asclera is supposed to cause less discomfort and discoloration when compared to hypertonic saline (concentrated form of sterile salt water). Another popular sclerosing agent is Sotradechol. Many surgeons use a combination of injecting spider veins and lasering spider veins.   Spider vein treatment is considered cosmetic by most insurance companies.
