Mirena is approved for contraception for how long?

• A. 4 years
• B. 6 years
• C. 8 years
• D. 10 years

Answer: (C)

Mirena is a hormonal intrauterine device intended as long-acting reversible contraception. It releases levonorgestrel locally to prevent pregnancy while staying in place for a prolonged period without daily action from the user. The labeling specifies that Mirena provides contraception for up to eight years. This duration reflects the clinical data showing sustained effectiveness and an acceptable safety profile for eight years; beyond that, the device’s performance and safety are not established, so replacement or removal is recommended. The other options fall outside the labeled use—four and six years are shorter than the approved period, and ten years goes beyond what the label supports.
