Can I Leave My Menstrual Cup In for 24 Hours?

Menstrual cups are a popular, eco-friendly alternative to pads and tampons, loved for their comfort and long wear time. But a common question many users ask is: Can I leave my menstrual cup in for 24 hours?

Recommended Wearing Time for Menstrual Cups

Most menstrual cup manufacturers and health experts recommend wearing the cup for up to 12 hours at a time. This is generally safe for most people, whether you have a light or heavy flow.

Why Not 24 Hours?

  • Risk of infections: Leaving any menstrual product in for longer than recommended can increase the risk of bacterial growth and infections, including Toxic Shock Syndrome (TSS), although TSS risk is lower with cups than with tampons.

  • Comfort: After 12 hours, your cup may feel full or cause slight discomfort.

  • Leakage: A full cup can leak, defeating the purpose of using it.

When Might Longer Wear Be Okay?

Some people with very light flows or who use smaller cup sizes might find they can comfortably wear a menstrual cup a bit longer — but it’s still safest not to exceed 12-16 hours.

Tips for Safe Menstrual Cup Use

  • Empty and clean your cup at least twice a day.

  • Wash your hands thoroughly before insertion and removal.

  • Sterilize your cup before and after your period by boiling it for 2-3 minutes.

  • Choose the right size for your flow and anatomy.

What If I Accidentally Leave It In Longer?

If you accidentally leave your cup in for over 12 hours, don’t panic. Remove it as soon as possible, rinse with clean water, and monitor for any unusual symptoms like discomfort or odor. If symptoms occur, consult a healthcare professional.
