Are menstrual cups safe?

Menstrual cups can be used by most menstruating people of all ages. With the correct cup size and proper hygiene practices, your cup will allow you to maintain an active lifestyle while it is inserted.

There are some risks you should be aware of when considering using a cup or if you are a cup user.

1. Material, allergies and sensitive skin

The silicone used in the manufacture of JuJu cups is 100% medical grade silicone and has been independently evaluated for biosafety. JuJu cups are hypoallergenic and do not contain any additional colours or dyes, are latex and BPA free, fragrance-free and free from bleaches and absorbency agents.

Whilst medical grade silicone allergies are rare we recommend you discontinue use of your menstrual cup if you develop a red, raised (bumpy or swollen) or itchy rash in the area or contact with the menstrual cup and consult an allergy specialist for a diagnosis.

2. Toxic shock syndrome (TSS)

If you have previously suffered from TSS, it is recommended that no internal sanitary products, including tampons and menstrual cups, be used again unless under the direction of your medical practitioner. The recommended maximum time for how long can you leave a menstrual cup in is no longer than eight hours. Leaving the cup in any longer may encourage the growth of harmful bacteria.

3. Birth control and intrauterine devices IUDs

JuJu can be used in conjunction with the oral pill and contraceptive injection.

If you are looking to use the JuJu cup in conjunction with an IUD such as Mirena, it is advisable that you consult a medical professional for proper guidance. There are specific directions which may need to be followed if a menstrual cup is to be used in conjunction with an IUD. Read more on menstrual cups and IUDs.

JuJu should not be considered a method of contraception and will not protect you against pregnancy.

4. Sexually transmitted infections (STIs)

A menstrual cup will not protect against sexually transmitted infections or diseases (STI/STD). Before engaging in intercourse, ensure that the JuJu cup has been removed. Failure to remove your menstrual cup prior to having sex may result in the cup getting stuck or the stem on the cup may cause injury to your partner.

5. Unable to remove a menstrual cup

A menstrual cup getting stuck is rare but can happen if you have a particularly long vaginal canal/high cervix or if you have allowed the cup to open too high in the vaginal canal which may result in the cup suctioning to the cervix, as opposed to the with the vaginal walls. Please see menstrual cup removal tips if you are having difficulty removing your menstrual cup.


Are menstrual cups hygienic?

Menstrual cups are hygienic, however maintaining good hygiene practices is important when using any internal sanitary product.

Always thoroughly wash your hands every time you insert or remove your cup and follow the menstrual cup cleaning guide

Your JuJu Cup is intended for personal use only and should never be shared with another individual. Sharing a cup can result in the transmission of STDs. Ensure you read usage guide prior to using your cup.


Can I use a menstrual cup after having a baby?

JuJu menstrual cup is not suitable for use postpartum. A menstrual cup is not recommended while you are still bleeding following childbirth, following a miscarriage or termination or during labour. Vaginal tenderness, swelling, bruising and open wounds may be agitated by a menstrual cup and the use of a cup may increase your risk of infection.

JuJu should only be used once your normal menstrual cycle returns and following your final check up with your Obstetrician, Gynecologist or GP which is usually performed around 6 weeks after giving birth.


Will a menstrual cup give me thrush?

While there is no evidence a menstrual cup increases the risk of thrush, preventative measures can be taken to reduce the risk of its onset. See more on thrush/yeast infections. If you are suffering from thrush, please discontinue the use of your menstrual cup immediately. 


What is the JuJu Cup made of?

JuJu Cup is made from a medical grade silicone.

JuJu menstrual cups are made in Australia. They are manufactured in a clean, sterile environment in adherence to strict standards set by the International Organisation for Standardisation (ISO).

During the research and design phase of JuJu, some of Australia's leading ergonomists and product designers were consulted to create a high-quality product.


How often should I empty my menstrual cup?

Menstrual cups should be emptied every 8 hours. If you have a heavy flow you may need to empty your cup more often. 

Our previously recommended empty frequency of 12 hours was updated to 8 hours in 2017 following a review of the usage guide by TGA clinical evaluators in order to minimise the risk of the growth of bacteria.

Set an alarm if you are prone to forgetting to remove and empty your menstrual cup.

We also recommend you empty your cup before going to sleep and after you wake.


Can I get TSS from using a menstrual cup?

TSS is a bacterial infection that has been linked to prolonged use of some high-absorbency tampons.

TSS can be life-threatening and is characterised by the following symptoms; fever, vomiting, diarrhea, a skin rash that looks like sunburn, peeling patches of skin on the feet and hands, muscular aches, headaches, a sore throat, red eyes, confusion, a drop in blood pressure, joint pains, sensitivity to light, kidney failure, fainting or collapsing.

If you experience any of these symptoms you should remove your menstrual cup immediately and contact the local emergency department.

People who have previously experienced TSS should not use any form of internal sanitary protection such as JuJu unless done so under the direct supervision of a qualified medical practitioner.

Can I use a menstrual cup with a Mirena® or another IUD?

In 2012 a study of 930 participants conducted investigated the use of tampons and menstrual cups and if there was any correlation to early IUD expulsion. The study concluded that "there is no evidence that women who report using menstrual cups or tampons for menstrual protection had higher rates of early IUD expulsion"

That said, we still strongly recommend you seek the advice of your medical practitioner/gynaecologist should you wish to use a menstrual cup in conjunction with an IUD. Your doctor may trim the IUD strings if they are long or sit low in the vaginal canal. 

If your GP has given you the all clear to use a cup in conjunction with your IUD, it is recommended you;

  1. Ensure you have the right size menstrual cup
  2. Wait for 2 full cycles after the insertion of your IUD before using JuJu to give your IUD time to settle.
  3. Follow the regular usage guidelines taking care to;
    • ensure you place your JuJu low, near the vaginal opening, as the cervix and the IUD strings often sit lower during your period
    • always ensure you break the suction seal prior to removing as per the removal instructions to avoid dislodging your IUD
    • remove the cup slowly 

Can I use a JuJu cup if I have sensitive skin or latex allergies?

Yes. JuJu is made from a medical grade silicone. It does not contain any toxins, bleaches or BPAs. JuJu does not contain any dyes and is latex-free so it is suitable for people with latex allergies.


Will a menstrual cup give me thrush?

There is currently no known evidence to support an increased risk of a yeast infection (candida albicans) with a menstrual cup.

It is estimated that 75% of people experience thrush at some time and whilst thrush does not cause any long-term health issues it can be very uncomfortable and can be recurrent. 

Thrush presents as vaginal discomfort, tears in the skin, abnormal discharge, stinging, itching or swelling. If you are experiencing any of these symptoms, we recommend you consult your GP as soon as possible for correct diagnosis and appropriate treatment. 

There are preventative measures you can take to reduce your risk of a yeast infection;

Cleaning your cup

Rinse your cup thoroughly after washing to ensure there is no soapy residue left on the cup as this can upset your pH balance.

Vaginal Irritation

  • Discontinue the use of your cup if you experience irritation from inserting or removing your JuJu.
  • Rubbing caused by a cup sitting low may due to incorrect insertion or anatomical reasons such as pelvic organ prolapse, poor pelvic floor tone or a low cervix. This may cause discomfort so remember, it’s fine to take a break from your cup whilst you are learning to use it and return to using tampons or pads for a couple of days.
  • Take it slow if using a menstrual cup is a big change for you and seek medical advice if you feel there are anatomical or medical reasons for your discomfort.
  • Practice inserting and removing your cup a couple of times a week when you do not have your period. We recommend you do this in the shower as you will be relaxed and you can use some warm water on the cup to lubricate it.
  • Doing a few ‘dry runs’ before your period starts will make the transition to using a cup easier.
  • Do not do this if you have used your cup when you have had a yeast infection as you may risk re-infecting yourself.
  • Avoid lubricants and find an alternative to latex condoms if you find they are causing irritation.


Cleaning your Body

  • Avoid perfumed soap or wash.
  • Avoid vaginal deodorants.
  • Avoid perfumed toilet paper and personal wipes.
  • Do not douche as this can destroy good bacteria.
  • Wipe from front to back to avoid a spread of the infection to the vagina.



  • Try to keep your diet consistent during your cycle.
  • Reducing the number of refined carbohydrates and sugars you eat can help reduce the risk of infection as thrush thrives on sugar.
  • Garlic supplements may help fight infection as they are a natural antibiotic.
  • Vitamin C can boost your bodies immune system.
  • Acidophilus Bifidus (aka probiotics) can be taken to help promote the growth of ‘good bacteria particularly if you have recently taken antibiotics.
  • Check with your GP if you are on any medication before taking supplements.



  • Wear loose clothing made from natural fibres that allow the vaginal area to breathe.
  • Avoid synthetic underwear and pantyhose. Stockings are a better option than pantyhose.
  • Avoid tight-fitting jeans or pants.
  • Change your washing powder or liquid if you think this may be the cause of recurrent infection.
  • Avoid fabric softeners as they are often scented.
  • If you have any concerns, please seek the advice of your medical practitioner. 


Can I use a menstrual cup if I have thrush?

We recommend you discontinue the use of your menstrual cup and do not use any internal treatment creams in conjunction with your menstrual cup.

It is best to replace your menstrual cup to eliminate the risk of reinfection and only use your new menstrual cup once the infection has completely cleared.


Can I share a menstrual cup?

We'd love you to spread the word about JuJu to your friends but please never share your own JuJu with anyone else.

JuJu is intended for your personal use only and sharing your cup with another person may transmit infections or diseases.


Can I wear a menstrual cup when exercising?

Yes. Since JuJu is worn internally and has no strings or wings like tampons and pads, it is perfectly suited to the active woman's lifestyle. JuJu also holds three times as much fluid as tampons or pads so only needs to be changed half as often as other disposable forms of feminine hygiene. JuJu can be worn when swimming, doing yoga, running or any other form of exercise.

Will a menstraul cup leak or slip out during exercise?

Generally speaking, there should be no impact on the effectiveness of a cup during exercise if the correct size cup is being used and a good seal has been formed. There are however, some cases where a menstrual cup may feel as though it is being pushed lower or feels like it is being expelled during high impact activities, squatting or deadlifting heavy weights which causes an increase in abdominal pressure. This may occur if a person has a particularly low cervix, suffers from pelvic organ prolapse and/or have experienced a loss in pelvic floor tone

Tip for exercising with a menstrual cup;

  1. Ensure you have the right size menstrual cup for your anatomy
  2. Follow the user guide, ensuring the cup is inserted at a 45-degree angle, not straight up
  3. Ensure a good seal has been formed
  4. Insert the cup when it is completely dry – having lubricant on the cup may cause it to slip lower


General exercise tips;

  1. Maintain good posture/form and brace your core before lifting heavy weights
  2. Build up to heavier weight gradually under the guidance of a qualified trainer
  3. If doing an activity hurts (not muscle soreness or fatigue but if an activity that makes you cringe or wince pain), don’t do. If the pain is chronic or persistent, pay attention to it and see a Physiotherapist.
  4. Perform regular kegel exercises to maintain good pelvic floor tone.  


Can I use a menstrual cup during sex?

JuJu should not be worn during sexual intercourse. Wearing a reusable menstrual cup during sex may cause injury to yourself or your partner. The menstrual cup may also be forced higher into the vaginal canal or cause it to get stuck to the cervix which will make removal difficult. 

JuJu is not a contraceptive and provides no protection against sexually transmitted diseases (STDs).


Can I wear a menstrual cup after giving birth?

Menstrual cups should not be used for post-partum bleeding. The use of internal sanitary products including menstrual cups, tampons and sponges increases the risk of infection and may prevent wounds from healing so only use pads only for bleeding after vaginal birth or a caesarean section. At around 6 weeks post birth you will have a postnatal check-up. Ask your Doctor at this appointment if it is OK to return to using your menstrual cup.


What size cup will I need after having a baby?

Once given the all clear by your Doctor at your postnatal check-up, you can use a menstrual cup for your period. If you already have a menstrual cup, check to see if the size you have is still a good fit for you. Many people are still able to use the smaller Model 1 post birth however most people find they need to size up to a Model 2 once they have had a baby. Some women also find they may need to switch to a Model 4 if they have lost some pelvic floor tone or their cervix sits lower after becoming.
