Kyleena is a hormonal coil similar to the Mirena, but is slightly smaller in size so it may be more comfortable to fit. It also has a lower dose of progestogen in it, so possibly fewer side effects than the Mirena coil
. Due to the low level of hormone, your bleeds may not be as light or more frequent than they would be on other hormonal coils. Kyleena can stay in for up to 5 years.
