Question: how long has the mini pill been around?
Answer: The first POP to be introduced contained 0.5 mg chlormadinone acetate and was marketed in Mexico and France in 1968. However, it was withdrawn in 1970 due to safety concerns pertaining to long-term animal toxicity studies. Subsequently, levonorgestrel 30 µg (brand name Microval) was marketed in Germany in 1971.
