Your menstrual cup or disc is the eco-friendly hero in your bathroom cabinet. It has saved you from countless tampon runs and liberated you from pads. But even these body-safe silicone heroes have an expiration date.
Knowing how often to replace your menstrual cup isn't just about hygiene. It's also about maintaining optimal menstrual cup performance and ensuring it works safely for your body. Considering a person can expect to use approximately 10,000 menstrual products in their lifetime, switching to a reusable option makes a significant impact throughout your menstrual cycle journey.
In this guide, we’ll walk you through the real lifespan of your cup or disc, the red flags to watch for, and simple care tips.
What Is The Real Lifespan of a Menstrual Cup?
A menstrual disc like nixit, for example, is designed to last up to five years with proper care.This multi-year lifespan is what makes it so sustainable and cost-effective over time.
It’s easy to get confused between how long you can wear your cup and how long the product itself lasts. Reusable menstrual cups are durable and designed to last months to multiple years, with longevity depending on proper care and material quality. High-quality cups are manufactured from medical-grade silicone, which is body-safe, durable, and resistant to bacterial growth when cared for properly.
The FDA classifies them as Class II medical devices, and their longevity depends on silicone quality and your cleaning routine.

Remember to remove, empty, and clean your cup or disc every 8-12 hours during your period. Rinsing with warm water between insertions helps maintain hygiene and keeps the silicone supple. This routine should be maintained consistently throughout each menstrual cycle for optimal hygiene and performance.
Fast-Track Lifespan Killers to Avoid
Certain habits can drastically shorten your cup or disc's life. This matters because proper menstrual cup or disc use ensures the product has less environmental impact than a single-use tampon or pad and can be reused for several years.
Here are the top offenders to avoid to protect your investment and your body.
Harsh Cleaners and Boil-Overs
Using oil-based soaps, bleach, or other harsh cleaning agents can degrade medical-grade silicone, making it sticky or brittle. Quality products made from medical-grade silicone are designed to withstand gentle cleaning methods without deterioration.

The same goes for over-boiling. Forgetting your menstrual cup on the stove can cause it to melt or warp, so set a timer and boil for just five minutes.
Wrong Lubricant Choice
If you're using lubricant to help with insertion, make sure it's water-based. A good option is nixit, which offers a non-sticky water-based lubricant that's pH-matched to vaginas and free from glycerin, parabens, and sugar.

Oil-based or silicone-based lubricants will degrade and break down the silicone material of your cup or disc over time. This degradation can compromise the integrity of the product, shortening its lifespan and potentially affecting its safety and effectiveness. Stick to water-based options to protect your investment and ensure your menstrual cup or disc lasts for years.
Physical Damage
Regularly inspect your menstrual cup or disc for signs of deterioration. This includes tiny cracks, a stretched-out rim, or tears near the stem. For a disc, you want to ensure the rim still has its flexible 'spring' to maintain a proper seal. Damaged products can cause discomfort during wear and may irritate sensitive tissue.
Damage can harbor bacteria and compromise the seal's ability to prevent leakage. Even minor damage can affect how the menstrual cup or disc sits within the vaginal canal, reducing effectiveness and comfort.
Odors, Stickiness, and Deep Stains
A lingering odor that won't wash out or a sticky film that remains after cleaning are signs that the silicone is breaking down. While light staining is often a cosmetic issue, a persistent foul smell means it's time for a replacement.
Warning/Important: Using harsh cleaning agents, such as bleach or oil-based soaps, can permanently damage the silicone. Always stick to pH-balanced cleansers and never over-boil your menstrual cup or disc to ensure its longevity and safety. |
Key Signs You Need a New Menstrual Period Cup
Not sure if it’s time? Grab your menstrual cup or disc and run through this quick checklist. If you find any of these red flags, it’s time to say goodbye.
For Menstrual Cups
- Visible cracks, scratches, or deep cuts in the silicone.
- The rim or stem is thinning, stretching, or showing signs of tearing, which can compromise the seal.
- The material feels powdery, chalky, flaking, or sticky after a thorough wash.
- A strong odor lingers even after a deep cleaning and boiling.
For Menstrual Discs
- The rim has warped, lost its flexible snap, or won't hold its shape.
- You find any punctures, surface snags, or tears in the thin basin.
- It's causing frequent leak issues despite correct placement in the vaginal canal.
- The material feels tacky, rough, or slimy to the touch.
If you spot any of these warning signs, it's time to retire your current menstrual cup or disc. Continuing to use the same cup when it shows signs of wear can compromise both safety and effectiveness.
While it may feel premature, using a compromised product can lead to leaks, discomfort, or even infection. A timely replacement ensures you continue enjoying the benefits of reusable period care safely and confidently.

Simple Hacks to Make Your Menstrual Cup Last
Proper care is the secret to getting the most out of your menstrual cup or disc. Understanding correct menstrual cup use is essential not just for comfort, but for extending the life of your product.
Follow these simple steps to keep it in top shape for years:
- Cleanse Correctly: Always use a pH-balanced, oil-free, and fragrance-free cleanser. A dedicated wash is formulated to be gentle on both your body and the silicone.
- Do a Monthly Boil: Between menstrual cycles, boil your menstrual cup or disc in a pot of water for five minutes to fully sanitize it and eliminate bacteria. Use a kitchen timer so you don’t forget!
- Store it Smartly: After cleaning and drying completely, ensure your menstrual cup or disc is stored properly in the breathable cotton pouch it came in. This prevents dust buildup and allows for air circulation.
- Perform Regular Inspections: At the end of each menstrual cycle, give it a quick once-over, checking for any of the early warning signs mentioned in our checklist.
Always use a pH-balanced, oil-free, and fragrance-free cleanser with warm water. A dedicated wash is formulated to be gentle on both your body and the silicone.
These small habits take just minutes but can add years to your menstrual cup or disc's lifespan. Think of it as a little self-care ritual that pays dividends, not just in money saved, but in reliable, worry-free periods cycle after cycle.
Pro Tip: After cleaning and sanitizing, make sure your menstrual cup or disc is stored properly in its breathable pouch. Airtight containers can trap moisture, which is the last thing you want for a medical-grade device between menstrual cycles. |

Frequently Asked Questions
Is surface discoloration dangerous?
No, light staining is normal and not a safety concern. It's purely cosmetic and happens over time due to the iron in your blood.
Are tiny stains okay?
Yes, faint stains are perfectly fine and do not mean your menstrual cup is dirty or needs replacing. You can try leaving it in the sun for a few hours, as UV rays are a natural brightener.
I dropped my disc in the toilet. Should I replace it?
It's a personal choice. Many people successfully sterilize their menstrual cup or disc after a toilet drop by submerging it in rolling, boiling water for 20 minutes (use a whisk or strainer to keep it from touching the bottom of the pan). That said, if you can't shake the ick factor or aren't confident in your sterilization method, it's perfectly okay to replace it for peace of mind.
Are menstrual cups still eco-friendly if replaced every few years?
Absolutely! Even if you replace your cup every two years, you are still diverting hundreds of disposable products from landfills.
