How long does Liletta last?
Liletta is a levonorgestrel-releasing intrauterine device (IUD). Its approved duration is up to 8 years for people who get the IUD for contraception [1].
When does it start working?
Liletta’s effectiveness depends on when it’s inserted during your menstrual cycle. If inserted at certain times, it can begin working immediately; otherwise, it may take up to about 7 days to become fully effective [1].
What happens after the duration ends?
Once Liletta reaches the end of its approved duration, it should be removed or replaced to keep contraception protection. Using it past the labeled timeframe is not recommended [1].
Does duration change if I’m using it for heavy periods?
Liletta is also used to help treat heavy menstrual bleeding. The duration guidance tied to its labeled use is the same overall timeframe (up to 8 years) [1].
Can it be removed earlier than the full term?
Yes. You can have Liletta removed at any time, and fertility generally returns after removal [1].
If I’m worried about pregnancy risk, what should I do?
If you think you might be pregnant (for example, missed periods or unusual symptoms) or you’re near the end of the device’s labeled duration, contact a clinician promptly for pregnancy testing and next steps.
