There isn't one replacement date that applies to every menstrual cup or reusable disc. Depending on the product, manufacturers may recommend anything from a couple of years to as long as 10 years with appropriate care.
The best guide is the information supplied with your specific product, together with regular checks for cracks, tears, changes in texture or other signs that the material is deteriorating.
How long does a menstrual cup or reusable disc last?
Lifespan varies considerably between products, even when they are made from similar materials. Manufacturer guidance can range from up to 2 years to up to 10 years.
These are manufacturer recommendations for those particular products, not a rule that can be applied to every menstrual cup or disc.
A product also doesn't necessarily need replacing simply because it has reached a certain age. Follow the replacement guidance for your product and regularly check that the material is still intact and behaving as intended.
Lifespan is not the same as wear time
Lifespan refers to how many months or years a reusable cup or disc may remain suitable for use. Wear time is how long it can be left in during a single use before it needs to be removed, emptied or cleaned.
For menstrual cups supplied in Australia, product information must specify a maximum duration of use of no more than 12 hours. Some manufacturers recommend a shorter interval, and your flow may mean you need to empty your cup much sooner.
Reusable menstrual discs have their own product-specific instructions, so follow the wear time stated by the manufacturer.
See How Long Can You Wear a Menstrual Cup or Disc? for more information.
When should you replace a menstrual cup or disc?
Inspect your reusable cup or disc regularly and replace it if the material shows clear signs of deterioration or damage.
Cracks, tears, splits or holes
Check the rim, body, base and any stem, loop, tab or other removal feature. Stop using the product if you find a crack, tear, split, puncture or other damage.
A sticky, tacky or changed surface
A change in texture can indicate that the material has deteriorated. If the surface becomes unusually sticky, tacky, oily or swollen, stop using it and check the manufacturer's replacement guidance.
A noticeable change in flexibility or shape
If a cup or disc becomes significantly harder, softer, distorted or less able to return to its usual shape, it may no longer sit or function as designed.
Persistent odour after correct cleaning
Some temporary odour can occur with reusable period products. Clean and sanitise the product using the method recommended by its manufacturer. If a strong odour remains, check the manufacturer's guidance to see whether replacement is recommended.
When it is time to replace your product, see How to Dispose of an Old Menstrual Cup or Disc.
Does staining mean you need a new cup or disc?
Usually not. Menstrual fluid can gradually discolour reusable cups and discs, and staining on its own does not generally mean the material has worn out.
Look instead for changes to the material itself, such as cracking, tearing, tackiness, distortion or a significant change in flexibility.
For help with discolouration, see How to Remove Menstrual Cup and Disc Stains.
How can you help your cup or disc last longer?
Follow the care instructions supplied with your specific product. Cleaning, sanitising and storage recommendations differ between brands and materials.
During use
- Wash your hands before handling the product.
- Clean it using the method recommended by the manufacturer.
- Use only cleansers and lubricants that are compatible with the material.
- Check the product for damage before reinserting it.
During insertion and removal
Handle the product gently and avoid sharp fingernails or objects that could nick or puncture the material.
For menstrual cups, release the seal before removal rather than pulling firmly on the stem. Reusable discs have different removal designs, including rims, notches, loops and tabs, so follow the instructions for your particular disc.
See How to Use a Menstrual Cup or How to Use a Menstrual Disc for step-by-step guidance.
Between periods
Sanitise your cup or disc using a method approved by its manufacturer. Some products can be boiled or steam sanitised, but temperatures and times vary.
Allow the product to dry and store it using the method recommended for that product. Many cups come with a breathable pouch, while some products are supplied with their own storage case.
Period Shop's cleaning products and cup and disc sanitisers may be useful, but always check compatibility with your particular product.
What if your cup or disc leaks or no longer feels right?
A change in leaking or comfort does not necessarily mean the product has reached the end of its life.
Cervix position, flow, placement, cup or disc size and changes in your body can all affect fit. If the product is intact but no longer works as well as it once did, troubleshoot the fit before assuming the material is worn out.
Use the Menstrual Cup Troubleshooter or Menstrual Disc Troubleshooter to work through common problems.
If your body or needs have changed and your current product no longer suits you, that may be a reason to choose a different size or design even if the original product itself is still in good condition.
Frequently asked questions
How many years does a menstrual cup last?
It depends on the product. Some manufacturers state that their menstrual cups can last up to 10 years with appropriate care, while other products have shorter recommended lifespans. Follow the guidance supplied with your cup and replace it sooner if the material becomes damaged or deteriorates.
How long does a reusable menstrual disc last?
Reusable disc lifespan varies between products. Some reusable silicone discs are marketed for up to 10 years, while others have much shorter recommended lifespans. For example, INTIMINA currently recommends replacing its Ziggy Cup reusable disc after up to two years. Check the instructions for your particular disc rather than applying cup lifespan advice to every reusable disc.
Do you have to replace a menstrual cup every year?
Not generally. Many reusable menstrual cups are designed to last for several years. There is no universal one-year replacement rule, so follow the manufacturer's lifespan guidance and regularly inspect the material for deterioration.
Does staining mean a menstrual cup or disc needs replacing?
Usually not. Staining is commonly cosmetic. A product may still be suitable to use if it is intact, cleans normally and has not developed cracks, tears, tackiness or other changes in the material.
Can silicone menstrual cups expire?
Silicone menstrual cups do not all have a single expiry date. Their recommended lifespan depends on the product and manufacturer. Over time, damage, material changes or incorrect care may mean a cup needs replacing even if it has not reached the manufacturer's maximum stated lifespan.
Should I replace my cup or disc if it starts leaking?
Not automatically. Leaking is often related to fit, position, flow or technique rather than material deterioration. Inspect the product for damage, then troubleshoot the fit before deciding whether replacement is necessary.
The bottom line
There is no single lifespan that applies to every menstrual cup or reusable disc. Some products are designed to last for many years, while others have shorter replacement recommendations.
Follow the guidance for your specific product and pay attention to its condition. Cracks, tears, tackiness, distortion or significant material changes are more useful reasons to replace a product than staining or age alone.
If your cup or disc is still in good condition but no longer suits your body, use the Period Product Comparison Hub or Find Your Best Fit Quiz to explore other options.
If use of a cup or disc causes persistent pain, irritation, unusual discharge or other concerning symptoms, stop using it and seek medical advice. If you suspect Toxic Shock Syndrome, seek emergency medical care. See our Toxic Shock Syndrome guide for more information.
