Should Babies be Weaned Before Having Sclerotherapy?

I would not recommend sclerotherapy while nursing. Although the risk of transfer of medication to the baby is probably small, there are no studies to prove that sclerotherapy with any agent is safe while breastfeeding. Treating the spider veins is elective and it would be safer to wait for treatment until the breastfeeding has ended.

Cosmetic procedures, including sclerotherapy, neurotoxins, fillers, and lasers are not recommended during pregnancy and nursing.  Effects on the baby are unknown and not worth taking the risk.
