We suggest that you talk with your personal physician, OB/GYN, or other health care provider concerning medical questions about either THE KEEPER or MOON CUP.


How does THE KEEPER or MOON CUP menstrual cup work ... how does it stay in place?

THE KEEPER or MOON CUP is designed to catch your menstrual flow rather than absorb it. Its bell shape allows THE KEEPER or MOON CUP to fit snuggly and comfortably up against your vaginal walls, below but not touching your cervix. The rim is designed to help create a suction that keeps THE KEEPER or MOON CUP in place and collects your menstrual flow inside of it. The small holes around the rim are to help release the suction when you remove the cup.


THE KEEPER and MOON CUP are both simple devices, that are easy to use.


What is the THE KEEPER made from?

THE KEEPER is made from natural gum rubber (latex).


What is the MOON CUP made from?

The MOON CUP is made from medical-grade silicone (non-latex).


What about latex allergy?

If you are sensitive to rubber, THE KEEPER may not be for you. Instead, please consider THE MOON CUP, which is made from non-latex medical-grade silicone and has all the benefits of THE KEEPER. Please consult with your physician, OB/GYN, or other health care provider if you are unsure if you have such an allergy.


Who makes THE KEEPER and THE MOON CUP?

THE KEEPER and THE MOON CUP are manufactured in America by THE KEEPER, Inc.

How long has THE KEEPER been available?

The KEEPER menstrual cup first came on the market in 1986 and is coming close to being available for 30 years.


Has THE KEEPER or MOON CUP been approved by the Food and Drug Administration (FDA)?

Yes. The FDA in America has approved them both.

Has Toxic Shock Syndrome (TSS) been an issue with THE KEEPER?

No. THE KEEPER has not been linked to TSS. It has been laboratory tested, and results have indicated that it is very unlikely to amplify the bacteria responsible for TSS. It is known that most of the cases of TSS that were tied to menstrual products occurred because tampons absorb menstrual fluid. The Keeper is non-absorbent.

Has Toxic Shock Syndrome (TSS) been an issue with THE MOON CUP?

No. The MOON CUP is a relatively new product. But, it is known that most of the cases of TSS that were tied to menstrual products occurred because tampons absorb menstrual fluid. We therefore think it is safe to assume that there will be no such problem with The MOON CUP, since it is non-absorbent.


Isn't THE KEEPER or MOON CUP a little expensive?

Comparatively speaking, no. Most other forms of feminine protection cost anywhere from $4.00 to $7.00 each month. The average cost of THE KEEPER or MOON CUP is only pennies per month over its useful life!


How long does THE KEEPER last?

With proper care (ex: no contact with harsh chemicals), THE KEEPER has a potential life expectancy of up to 10 years. Please see the Usage and Care page for specific instructions on caring for your KEEPER or MOON CUP to maximize its useful life.


How long does THE MOON CUP last?

The MOON CUP has not been on the market as long as THE KEEPER, so we cannot yet make any claims on its life expectancy.


Is it comfortable? It looks so big.

At first you may notice THE KEEPER or MOON CUP, but once you get used to it (usually during your first day of use), you will not be aware of its presence.


Is using a KEEPER or MOON CUP messy?

No, not once you get comfortable with it. In the beginning, you need to become accustomed to removing and emptying your KEEPER or MOON CUP. If the suction seal is not properly released before you remove the cup, it can sometimes be messy. Once you learn to release the cup properly, there should not be any problem. Pulling THE KEEPER or MOON CUP out too fast, or tipping it at too steep an angle could cause some messiness. Again, once you get some practice removing and emptying THE KEEPER or MOON CUP, things should be fine. Just remove the cup slowly and as close to straight down (with minimal tipping) as possible.


Will THE KEEPER or MOON CUP leak?

No, THE KEEPER or MOON CUP itself does not leak. However, there are conditions that could cause leakage. If the cup has not been inserted properly or if something has caused the cup to move out of place, some leakage may occur.


Will I be able to feel THE KEEPER or MOON CUP when it is inside?

Not if it has been properly inserted. If you do feel it, then it has probably not been inserted in the correct position and is too close to the vaginal opening. Adjust or reinsert THE KEEPER or MOON CUP slightly higher in the vaginal cavity. Remember, the entire stem remains outside of your body.


Is it possible for THE KEEPER or MOON CUP to get lost inside of me?

No.


Does THE KEEPER or MOON CUP touch or come close to the cervix?

No.


How often should THE KEEPER or MOON CUP be emptied?

You never want anything to stay in your body for an extended length of time without removing it. THE KEEPER or MOON CUP should be emptied and rinsed at least every 8 to 12 hours. Empty it more often if you are experiencing a heavy menstrual flow.


Can THE KEEPER or MOON CUP be worn overnight?

Yes.


When I urinate or have a bowel movement, do I need to remove my KEEPER or MOON CUP?

No. However, you may find that your KEEPER or MOON CUP has traveled down closer to the entrance of your vagina if you push your muscles harder than normal. So, the cup may need to be readjusted after urination or a bowel movement.


What if I need to empty my KEEPER or MOON CUP in a public restroom?

First, wash your hands. You may find it useful to take a wet paper towel into the stall with you. Remove, empty, and wipe THE KEEPER or MOON CUP before reinserting (you may use toilet tissue to do this). Then, use the wet paper towel to wipe off your fingers. Wash your hands again before leaving the restroom.


Can I wear THE KEEPER or MOON CUP during intercourse?

No. THE KEEPER or MOON CUP is positioned below the cervix and at the vaginal opening, so it would interfere with intercourse.


I sometimes use my diaphragm for menstrual protection. Does THE KEEPER or MOON CUP work as a method of birth control?

No. THE KEEPER or MOON CUP is NOT like a diaphragm and CANNOT be used as a method of birth control.


Can a virgin use THE KEEPER or MOON CUP?

Yes, it would be much like a tampon. However, if you have strong personal feelings about keeping the hymen "intact," you may not want to use THE KEEPER or MOON CUP. Please check with your personal physician for advice.


I have a tilted uterus, so can I use THE KEEPER or MOON CUP?

Yes.


I am physically active and very involved in sports. Can I wear THE KEEPER or MOON CUP?

Absolutely! Many women who are active in sports find KEEPER or MOON CUP very convenient and effective.


Can IUD users use a KEEPER or MOON CUP?

Yes, they can. But we suggest that you speak with your own personal physician, OB/GYN, or other health care provider when you have concerns about using THE KEEPER or MOON CUP.


What about possible infection?

A few women have found that their KEEPER or MOON CUP aggravated a urinary tract infection. Please check with your health care provider.

What if I have a yeast infection?

First and foremost, you must get medical treatment for your yeast infection. The manufacturer's (THE KEEPER, Inc.) consultants report that all that is needed to clean your KEEPER or MOON CUP is to simply clean it with warm soapy water. You may also soak your cup for a few minutes in a solution of one part vinegar in nine parts water (a 10% vinegar solution). However, do not soak your cup in this solution for more than a few minutes, as that can damage it and reduce its useful life. You may use a small, soft brush and a mild soap to gently clean THE KEEPER or MOON CUP before putting it away in its cloth bag until your next period.
