Care and Cleaning

The MedFem Menstrual cup can last for years with proper cleaning and care.

If you follow our instructions on how to use and clean your MedFem Menstrual cup it’s a very hygienic and safe method of managing your period.

You should always make sure to wash your hands with soap and water when handling your menstrual cup.

Before first use

Before using your MedFem Menstrual cup for the very first time, you have to boil your menstrual cup in water for 3-5 minutes. Please make sure to keep an eye on the pot so the water doesn’t vaporize, or the cup falls to the bottom and burns.

Can I sanitize my menstrual cup in a microwave

or pour boiling water over it?

We recommend that you boil it in a pot because it’s important to make sure the water reaches 100 degrees Celsius and kills any bacteria.

This is more difficult to control if you’re using a microwave and also when you simply pour boiling water over the cup, since the water’s temperature drops quickly.

During your period

While on your period, we recommend that you empty the cup in the toilet or sink and simply rinse it with clean water and reinsert it.

It’s not necessary to use soap to clean your cup, but if you prefer using soap, it’s important to use a perfume free and pH-balanced soap.

After your period

Once your period has finished, you have to boil your MedFem Menstrual cup in water for 3-5 minutes. Again, please make sure to keep an eye on it so it doesn’t accidentally burn.

If you are not able to boil your MedFem Menstrual cup, you can sanitize it using a Wipes.

After your MedFem Menstrual cup has dried, store it in the Breathable cotton Pouch.

If needed, you can wash the Breathable Cotton Pouch in the washer on 30 degrees Celsius.

If you have lost the bag, you can use any other cotton Pouch. 


Tips and tricks

Using MedFem Menstrual cup with an IUD

We have consulted a many gynecologist on the matter and as the MedFem Menstrual cup is placed low at the base of the vaginal canal, it shouldn’t interfere with an IUD. However, you should always make sure to release the suction seal when you’re removing the cup.

As with any other gynecological concern, we’d always recommend you talk with your gynecologist before you start using a cup with an IUD.


Discolouration of your MedFem Menstrual cup is due to the residual build-up and it is very normal. However, it is possible to make it look “as new” again with the following steps:

Buy some hydrogen peroxide 2% either online or in your local pharmacy/drugstore

In a bowl, mix 1/2 water and 1/2 hydrogen peroxide.
Submerge the cup and leave it overnight in the mixture.

This should make your cup appear almost as new. Just remember to clean it thoroughly before use!


Medical-grade silicone (the MedFem Menstrual cup material) is odorless. However, it is possible that your cup develops an odor with use.

The most common reason for a menstrual cup to develop a smell is that you leave it in for longer than the advised 8-12 hours.

Here are a few ways to eliminate the cup’s smell:

Soaking it in a hydrogen peroxide mix. Mix 1/2 hydrogen peroxide 2% and 1/2 water in a bowl. Submerge the cup and leave it overnight in the mixture. Just remember to boil the cup for 3-5 minutes before you use it again!

Using fresh lemon juice. You can either wipe the inside and outside of your cup with it or soaking your cup in the juice for around an hour. Once finished, boil your cup for a few minutes in water to ensure all residue is removed.

Rinsing the cup with cold water. After removing and emptying your menstrual cup, make sure to rinse it with cold water first. You can use lukewarm after if preferred. Using warm water first may cause the smell

Tip 1: Wear a panty liner until you feel comfortable

 Until you feel 100% comfortable with your menstrual cup, you might want to wear a panty liner so you don’t have to worry about leaking. 

Tip 2: Try to locate your cervix

 We all have differently positioned cervixes and the cup should be placed below the cervix, if not, it will most likely leak. Try to locate your cervix with your finger, you should feel for a slightly firmer area of tissue and position your cup under it. 

Tip 3: Trim the stem of the cup

 If you can feel the stem and find it uncomfortable after using the cup a couple of times, you can cut it shorter. However, do not trim the stem while the menstrual cup is inserted!

Tip 4: Practice before your period

No one expects you to be an instant menstrual cup pro, so we recommend you practice inserting and removing your cup before you get your period. 

Tip 5: Use lubrication

 You can use water or a water-based lubricant to make insertion easier.
