Is Delfen Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Delfen? Is Delfen safe for nursing mother and child? Does Delfen extracts into breast milk? Does Delfen has any long term or short term side effects on infants? Can Delfen influence milk supply or can Delfen decrease milk supply in lactating mothers?

Delfen is a relatively nontoxic nonionic surfactant and only trivial amounts of the drug have been found in the milk of animals after vaginal administration.[1] Limited information indicates that breastfed infants of mothers using vaginal Delfen experienced no adverse effects. Vaginal use of Delfen is acceptable in nursing mothers.

In a study comparing various methods of contraception, the breastfed infants of women who used a Delfen-containing foam had no observable adverse effects.[2]

Compared with a combination contraceptive containing ethinyl estradiol 30 mcg and levonorgestrel 150 mcg, women who used either Delfen foam or copper-T IUD had less inhibition of lactation than the combined oral contraceptive.[2]
