One of the best things about menstrual cups is that they can be reused again and again, for many years - saving waste, and saving money! But how long does a menstrual cup last, and how do you know when it’s time to be replaced?
Firstly, we should note that there is no ‘rule’ about the lifespan of a menstrual cup and that's why we don’t give a set time limit on when you should replace a menstrual cup or disc.
Medical-grade silicone and TPE are two common materials used in the manufacture of discs and cups. It is an incredibly durable material and some people find that they can use the same cup or disc for 7 years or more with no issues, whereas others might need to replace theirs after 2-3 years. It all depends on how often the cup is used, how long it is worn for, how well it is cared for and can even depend on your body’s individual pH!
Some menstrual cup users like to replace their cup every couple of years just for peace of mind, or if their cup has become stained (read about How to remove menstrual cup stains), although it is not necessary.
Signs It’s Time to Replace Your Menstrual Cup or Disc
How do you know when it’s time to replace your menstrual cup or disc? Here are some guidelines on what to look out for:
- Cracking or Tear Marks: You notice any cracks, tears, holes or other damage. Even though these might not affect how well the cup or disc performs, it can make the cup harder to clean properly and put you at an increased risk of infections like TSS.
- Persistent Odour: Your cup or disc develops an odour that can’t be removed with regular menstrual cup cleaning or menstrual disc cleaning
- Discolouration: The surface of your menstrual cup changes texture or colour (other than regular staining, which will look yellow or brown)
- Loss of Flexibility or Shape: If your cup or disc feels flimsy or stiffer than usual, it it doesn’t return to its original shape or if it becomes harder to insert or remove, it could indicate that the material has lost its flexibility, making it more difficult to form a proper seal.
- it may no longer provide the comfortable seal required for cups or become uncomfortable to insert and remove, this indicates that it’s time to replace it.
- Anatomical Changes: You need a different size after pregnancy or childbirth, or due to changes in your pelvic floor.
Why Should You Replace Your Menstrual Cup or Disc?
While it may be tempting to keep using your menstrual cup or disc well beyond its expected lifespan, doing so can lead to several issues including:
- Hygiene and Health Concerns: Over time, the materials used in menstrual cups and discs can break down, which may lead to bacterial build-up. Using an old, worn-out product increases the risk of infections such as bacterial vaginosis or yeast infections.
- Increased Risk of Toxic Shock Syndrome (TSS): Although rare, improper cleaning or using a damaged menstrual product can increase the risk of Toxic Shock Syndrome (TSS), a serious but rare condition caused by bacterial infection.
- Leaks and Discomfort: A worn-out menstrual cup or disc may not form a proper seal, leading to leaks, discomfort, or even spills. This can be especially problematic during heavy flow days or when engaging in physical activity.
- Decreased Effectiveness: A cup or disc that no longer maintains its elasticity or shape might not perform as effectively, leading to an overall decrease in its ability to contain menstrual flow.
Extending the Life of your Menstrual Cup or Disc
Caring for your reusables by following the detailed cleaning and care instructions set out by the manufacturer is the best way to get as many years of use as possible. Always be extra mindful to:
- Clean Thoroughly: Wash your menstrual cup or disc with mild, unscented soap and warm water after each use and sterilise your cup at the end of each cycle by boiling it in water for a few minutes.
- Set an alarm: When boiling your Menstrual Cup or Disc to avoid over-boiling or burning on the stove.
- Avoid Harsh Chemicals: Don’t use bleach, harsh detergents, or fragrances to clean your menstrual products, as these can degrade the material.
-
Use the Correct Removal Technique:
- Never pull the stem or tail of your cup or disc when removing it. The stem and tail are designed to help you locate the cup inside you and move it slightly lower in the vaginal canal, but you should always pinch the base of the cup or disc to remove it. Pulling on the stem or tail can cause it to weaken over time and break.
- Don't use fingernails to grip the cup or disc as this can cause small tears or nicks in the cup or disc. Instead, grip the cup or disc with the finger pads of the index finger and thumb.
- Inspect Regularly: Before each use, check your menstrual cup or disc for any signs of damage, wear, or discolouration. If you spot anything unusual, it’s time to replace it.
- Cold Water Rinse: Prevent staining by rinsing your cup or disc in cold water first and never exceed the recommended wear time.
- Store Properly: Store your menstrual cup or disc in a breathable fabric pouch to avoid exposure to heat and light, which can cause degradation. Avoid storing them in plastic bags or airtight containers, as this can increase the risk of bacterial growth.
With proper care, your cup or disc will give you many years of period bliss!
