Levonorgestrel Implant

This record contains information specific to the levonorgestrel implant, which is not available in the United States. Although nonhormonal methods are preferred during breastfeeding, progestin-only contraceptives such as levonorgestrel are considered the hormonal contraceptives of choice during lactation. Fair quality evidence indicates that levonorgestrel does not adversely affect the composition of milk, the growth and development of the infant. Expert opinion and a metanalysis hold that the risks of progestin-only contraceptive products usually are acceptable for nursing mothers at any time postpartum.[1-5] A meta-analysis that immediate postpartum progestin contraceptive implant insertion (etonogestrel or levonorgestrel) does not interfere with lactogenesis, and does not reduce breastfeeding continuation at three or six months.[6] Some evidence indicates that progestin-only contraceptives may offer protection against bone mineral density loss during lactation, or at least do not exacerbate it.[7-9]
