The ring is inserted into the vagina and left for 21 days, then removed, washed and stored for seven days, during which the user experiences a period (withdrawal bleeding.) This can be repeated thirteen times, for one full year of use.[8] Unlike NuvaRing, another vaginal ring contraceptive, the combination ring does not need to be refrigerated before being dispensed and can be stored at room temperature up to 30 degrees Celsius.[3]
The medication was developed by the Population Council, an international non-profit organization, and licensed to TherapeuticsMD.[7] It was approved for medical use in the United States in August 2018,[9] and in Canada in December 2024.[1]
