Lutera vs. Mirena
See how Lutera and Mirena compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Lutera is a daily pill taken at the same time each day, while Mirena is a hormonal IUD placed once by a clinician and left in for up to 8 years.
Both release a progestin hormone to prevent pregnancy, but Mirena is also FDA-approved to treat heavy menstrual bleeding for up to 5 years.
Lutera depends on daily user adherence and carries clot risks tied to estrogen, while Mirena requires an insertion procedure and carries device-specific risks like expulsion.

Roughly $20 to $99 per month before insurance, less upfront than Mirena's device cost

Increased clot risk, especially for smokers over 35
Not recommended right after childbirth due to clot risk
