Are Menstrual Cups Safe? What You Need to Know.

Menstrual cups are safe provided good hygiene is practice and the usage guidelines are followed.

Whilst menstrual cups can be used by most menstruating people of all ages and with varying anatomical differences, there are a number of considerations you should take into account prior to using a menstrual cup.

Anatomical differences

There may be some anatomical differences or conditions such as vaginismus, pelvic organ prolapse, retroversion of the uterus or loss of pelvic floor tone, which may make it too difficult for some people to use a menstrual cup. Some people also find one particular brand of cup may work better for their anatomy than another as different cups have different shapes and design features.

If you have any concerns or question regarding the suitability of a menstrual cup in your particular situation, you are advised to seek the advice of a qualified health care professional.

Skin irritation

Skin irritation may occur;

  • when inserting or removing a menstrual cup
  • if the menstrual cup has not been lubricated
  • if residual cleaning soaps are left on the cup or
  • if an incorrect size has been selected

This is most likely to happen whilst learning to use a menstrual cup for the first time. Follow these first-time tips for using a menstrual cup prior to using a menstrual cup to avoid skin irritation. 

Silicone allergies

JuJu cups are made of 100% medical grade silicone. 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 of contact with the menstrual cup and consult an allergy specialist for a diagnosis.

JuJu cups are latex-free, BPA free, fragrance-free and free from bleaches and absorbency agents. The clear JuJu cup does not contain any pigments for colouring and the silicone used in the manufacture of JuJu cups has been independently evaluated for biosafety. 

Toxic shock syndrome (TSS)

TSS is a rare but serious disease that has been associated with internal personal care products and may be life-threatening.

It is important to keep your menstrual cup clean and do not exceed the maximum wear time of 8 hours. Leaving the cup in for longer than 8 hours may encourage the growth of harmful bacteria and put you at risk of contracting TSS.

If you experience any of signs or symptoms of TSS immediately remove your menstrual cup and go to your nearest hospitals emergency department. 

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.

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 menstrual cup should not be worn during penetrative intercourse. Menstrual cups are not a method of contraception and will not protect against pregnancy.

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 being pushed up and suctioning to the cervix which will be difficult to remove and may cause injury to your partner.

Unable to remove a menstrual cup

A menstrual cup getting stuck is rare but can happen if you have a particularly long vaginal canal or 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. 

See the menstrual cup removal tips if you are having difficulty removing your menstrual cup.


Menstrual cups are single person use products 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. 

Postpartum bleeding

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

Menstrual cups 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.

Thrush or infection

Whilst there is no evidence menstrual cups are a direct cause of infections such as bacterial vaginosis (BV) or vaginal thrush, these infections may occur if vaginal pH levels are out of balance and whilst using a menstrual cup.

Discontinue use of your menstrual cup if you have an infection or yeast overgrowth. Over the counter medication is available for the treatment of thrush and a doctor should be consulted if you suspect you have BV.

Follow these tips to preventative vaginal thrush.

Correct storage of your menstrual cup

Wash and disinfect your menstrual cup prior to storing it.

Always store JuJu in a ventilated area; never keep in a plastic bag or airtight container as moisture cannot evaporate without airflow and your cup will not dry.

Keep menstrual cups out of reach of children and animals.
