This is why I was peeved about not knowing that it contained hormones (again, I SHOULD have done my homework before stupidly allowing my OB to insert one at the 6-week postpartum exam... she knew I was nursing, even told me this was a great compromise over the pill because of the nursing...).
My understanding is that the FDA doesn't recommend any hormonal contraception in breastfeeding moms, but it can still be used safely. :
Progestogen-only contraceptives such as an IUS are not believed to affect milk supply or infant growth. However, a study in the Mirena application for FDA approval found a lower continuation of breastfeeding at 75 days in IUS users (44%) versus copper IUD users (79%).
Levornogestrel is found in nursing infants at 7% of the concentration found in their mothers using the Mirena IUS. A six-year study of breastfed infants whose mothers used a levonorgestrel-only method of birth control found the infants had increased risk of respiratory infections and eye infections, though a lower risk of neurological conditions, compared to infants whose mothers used a copper IUD. No longer-term studies have been performed to assess the long-term effects on infants of levornogestrel in breast milk.
There are conflicting recommendations about use of Mirena while breastfeeding. The U.S. FDA does not recommend any hormonal method, including Mirena, as a first choice contraceptives for nursing mothers. The World Health Organization recommends against immediate postpartum insertion, citing increased expulsion rates. It also reports concerns about potential effects on the infant's liver and brain development in the first six weeks postpartum. However, it recommends offering Mirena as a contraceptive option beginning at six weeks postpartum even to nursing women. Planned Parenthood offers Mirena as a contraceptive option for breastfeeding women beginning at four weeks postpartum.
