How Long Can I Wear It For?

You can wear Casco Cup for up to 12 hours, though it's a good idea to change it more often than that.

How Do I Use Casco Cup?

Great question. Check out our best menstrual cup guide for step-by-step instructions. Easy-peasy.

What's My Size?

Take our menstrual cup quiz to find your size. Still not sure? We recommend the Mini for users under 18 or anyone with a low cervix, the Size 1 for most other menstruators, and the Size 2 for anyone who has given birth.

Can I Use Casco Cup If I'm Pregnant?

No. Speak with your gynecologist.

Can I Use the Casco Cup If I'm Going Through Menopause?

Yes. In fact, many women who are going through menopause prefer the Casco Cup because, until tampons, it does not dry out the vagina and helps maintain healthy vaginal pH.

I Have an IUD. Can I Wear a Cup?

Please check with your gynecologist before attempting to use Casco Cup with an IUD. They may recommend trimming your IUD strings or not using one at all.

Can I Use a Casco Cup During Menarche?

Yes, but if you have questions speak with your doctor.

How Do I Clean It?

Cleaning your Casco Cup is critical. We recommend rinsing it out with cold water between uses whenever possible. Additionally, we recommend boiling it a minimum of once per cycle and once at the end of your cycle before putting it away. This means leaving your cup fully submerged in boiling water for several minutes.

Some brands sell washes and other things you don't need. The best (and more affordable) way to clean Casco Cup is the old fashioned way: boiling water.
