About levonorgestrel
Levonorgestrel was first created in the 1960s and began to be used as a contraceptive in the 1980s. It was officially commercialized in France as NorLevo in France in 1999, and has been officially approved in each country since then. It is one of the essential medicines of the World Health Organization and the most important medicine that is indispensable to the basic health system. It is available as a generic drug. The wholesale price of the dose required for emergency contraception is $ 0.23 – 1.65. In the United States, it is sold as an over-the-counter drug for all age groups.
In Japan, the introduction was delayed and it was approved as an emergency contraceptive drug Norrevo on February 23, 2011 (only Japan and North Korea did not approve it in Asia). It is not sold as an over-the-counter drug, and on July 26, 2017, the Ministry of Health, Labor and Welfare's "Evaluation Review Conference on Conversion from Medical Use to Guidance Required / General Use" considered conversion to over-the-counter drugs. It was shelved as premature.
