Is it safe to have the hormones from the IUD inside you all the time?

Yes. Levonorgestrel is the hormone used in the hormonal IUDs—Mirena, Liletta, Kyleena, and Skyla—and it’s used in other birth control methods too. It’s a synthetic version of progesterone, a hormone made by the body. It’s been studied and found to be very safe. If you decide to get your IUD removed, the hormones will be out of your body within a day or two.

Still not working?

Want to use a method that doesn’t have any hormones, try the non-hormonal, copper IUD. You can also try other non-hormonal methods, including the diaphragm, condoms, or internal condoms.
