You will need to empty your MCUK at least every 4-8 hours, depending on your menstrual flow.

Our recommendation to empty and rinse the MCUK every 4 – 8 hours is based upon safe practice for users and has nothing to do with the capacity of the MCUK menstrual cup vs. other period cup brands.

This recommendation is based on safety and hygiene reasons: to limit the risk of infections for our MCUK customers. It is also important to note that some regulatory bodies, such as the Therapeutic Goods Administration in Australia (TGA) and ANSES in France, state that a menstrual cup should not be worn for longer than 8 hours.

As the MCUK menstrual cup holds three times more than a regular tampon, most MCUK users find they need to empty their MCUK less often than they previously had to change tampons or pads.
