Flex Disc should not be worn for more than 12 hours. After 12 hours, you must remove the disc, dispose of it, and insert a new one.
Both menstrual discs and cups are regulated by the FDA; they have established that the maximum wear time for these products is 12hrs. We urge you to use our products as directed.
We know that the disc can be so comfortable, you may forget about it, so we highly recommend setting a reminder or alarm on your phone so you don't forget to change it when the time comes!
