The hormonal 
intrauterine system (IUS)

The levonorgestrel intrauterine system (IUS)—also known as the hormonal IUS—is a highly effective, long-acting, reversible contraceptive with additional non-contraceptive health benefits, including a reduction in menstrual cramps and blood loss, fewer side effects compared to other hormonal methods, and alleviation of anemia for some women. Despite its advantages, availability and use of the method globally has been limited in low-resource settings around the world. This may be changing as new, more affordable hormonal IUS products enter the global market.

*Note: Manufacturers' labels for LNG IUS products do not currently include an indication for immediate postpartum insertions. However, the World Health Organization's Medical Eligibility Criteria for Contraceptive Use categorizes immediate postpartum insertion [<48 hours] of the LNG IUS as a category 1 [no restrictions] in non-breastfeeding women and as a category 2 [benefits outweigh the risks] in breastfeeding women.
