Most women have a significant decrease in uterine blood loss with the LNg IUD. Some studies report up to a 95% reduction in blood loss.1 Increased spotting during the first couple of months is common, followed by less bleeding thereafter.
What are common side effects?
The LNg IUD can reduce menstrual bleeding and cramps and, in many women, eventually cause menstrual periods to stop altogether. In this case, not menstruating is not harmful.
The LNg IUD may cause hormonal side effects similar to those caused by oral contraceptives.
