Recommendations for continuous use of the menstrual cup

The menstrual cup is the best alternative to tampons or pads for your period. Although there is no global standard, the recommendation for duration of continuous use of a menstrual cup from Ruby Cup, our partner, is a maximum of 8 hours between insertion and removal to empty and clean the cup.

Menstrual cups are very comfortable and safe

For those who do not yet know of it, the menstrual cup is a product for menstruation for internal use, it is inserted into the vagina and collects the menstrual flow (instead of absorbing the flow like a tampon does ). Being a reusable and very comfortable product, the menstrual cup is the best alternative to tampons and pads for periods.


Typically composed of medical grade silicone, the menstrual cup is flexible and soft and does not cause discomfort when inserting or removing. If you still are not familiar with and want to see instructions for use, we recommend you read this excellent guide for beginners from Rubycup.


In addition, menstrual cups are very durable with a lifespan of more than 10 years.

Its silicone composition makes the menstrual cup hypoallergenic, non-absorbent and does not contain additives or harmful chemicals. This makes the cup very safe and better for your health than disposable products which frequently contain both plastics and other harmful chemicals.


A recent study published by the prestigious medical journal "The Lancet" concludes that the menstrual cup is safe and better than disposable products.


Like any other product, menstrual cups need to be used correctly, giving attention to hygiene measures when inserting and emptying it as well as when sterilizing and storing it between each cycle.


What is the recommended wearing time of the menstrual cup? 

Despite being very safe, leaving the cup in for too long without emptying carries the risk of bacteria proliferation in the vagina and this is why there is a maximum recommended time of continuous use. 

At the moment there is no standard between the recommendation of different brands with some suggesting a maximum of 12 or 8 hours, Ruby Cup, our partner at Redpanti, prefers to use caution and therefore recommends a maximum use of 8 continuous hours use of their menstrual cup.

This maximum wear time may be shorter during heavy flow days, as the cup must be emptied once full to avoid any leakage.


Is there a risk that the menstrual cup can cause toxic shock syndrome?

Toxic Shock Syndrome (TSS) is a very rare but life-threatening condition associated with tampon use in which bacteria that usually live on the skin penetrate deeper into the body. The risk of TSS associated with a menstrual cup is very low globally and well below that of tampons but it is not risk 0.

This risk can be reduced by washing the hands thoroughly with soap and water before and after handling the cup, also by emptying and rinsing the menstrual cup every 8 hours.


Is it recommended to sleep with a menstrual cup on?

Yes you can use a menstrual cup at night. However, if you tend to sleep longer than eight hours, you may prefer to use a washable pad or menstrual underwear, as menstrual cups (like tampons) should not be worn for more than eight hours.

Our recommendations for optimal use of the menstrual cup:

  • Wash your hands well with soap and water before using your menstrual cup.
  • Rinse your menstrual cup with water before and after use.
  • Do not leave your menstrual cup more than 8 hours without emptying and rinsing.
  • Disinfect your menstrual cup at the end of the cycle, either by boiling in a container of water for 2-3 minutes or using Rubycup Sterilizer.
