Not risky for breastfeeding or infant.
Various locally-applied products to treat varicose sclerosis: aqueous saline solution, microfoam, hydroxy-polyethoxy-dodecane, sodium tetradecyl sulfate, polidocanol / lauromacrogol, chromated glycerin, sodium salicylate, etc. (MedlinePlus 2017) are irritants that, when applied correctly, do not enter the bloodstream in significant quantities and, therefore, neither to breastmilk.
Other procedures to treat varicose veins, such as laser, cryosclerosis, phlebectomy or varicose vein ablation, also do not affect breastfeeding.
It is not intended to replace the relationship you have with your doctor but to compound it.
Thank you for helping to protect and promote breastfeeding.
