The MIRENA intrauterine system releases levonorgestrel at 20 mcg/day and is licensed for which of the following durations in the UK/India for contraception?
- A 5 years ✓
- B 3 years
- C 7 years
- D 10 years
Correct answer: A. 5 years
Explanation
The Mirena LNG-IUS is licensed for 5 years for contraception (and 5 years for management of heavy menstrual bleeding). However, research data show efficacy up to 7 years, and the device is now licensed for 8 years in some countries. For the purpose of NEET-PG examination based on standard textbook teaching, 5 years remains the standard licensed duration for contraception. Copper IUCDs like the Cu-T 380A are licensed for 10 years.
