Are menstrual cups FDA approved?

Yes, menstrual cups are legally sold as FDA-regulated medical devices in the U.S.—but there’s a critical distinction between FDA clearance and FDA approval. Here’s what every user needs to know:

🏛️ The FDA’s Role: Regulation vs. Approval

  • Menstrual cups are Class II medical devices (like pregnancy tests and tampons).

  • They receive FDA clearance via the 510(k) pathway, NOT full approval.

  • What 510(k) means: The FDA "clears" a cup if it proves it’s substantially equivalent to an already legally marketed device (a "predicate"). No brand-new safety testing is required.

✅ What FDA Clearance GUARANTEES

Before a cup can be sold in the U.S., the FDA requires:

  1. Material Safety:

    • Medical-grade silicone or TPE must be used (non-toxic, hypoallergenic).

    • No latex, BPA, or phthalates.

  2. Biocompatibility Testing:

    • Proves the material won’t irritate skin/mucous membranes.

  3. Labeling Accuracy:

    • Capacity claims (e.g., 30ml) must be proven.

    • Wear time (max 12 hours) must be stated.

  4. Manufacturing Standards:

    • Factories pass FDA inspections for hygiene and quality control.

⚠️ What FDA Clearance Does NOT Mean

  1. No Long-Term Safety Studies:

    • The FDA doesn’t require decades of data (cups are considered low-risk).

  2. No Brand-Specific Testing:

    • If Brand A’s cup is cleared, Brand B can reference it as a "predicate" without new safety data.

  3. No TSS Prevention:

    • Cups carry a TSS risk (however small). Labels must warn users.

🔍 How to Spot FDA-Cleared Cups

  1. Check Packaging/Labeling:

    • Must display: "Cleared by the FDA" or "FDA Registered Facility."

  2. Look for 510(k) Number:

    • e.g., "K123456" (found on packaging or company website).

  3. Verify in FDA Database:

Popular FDA-Cleared Brands:

  • DivaCup | Saalt | Lunette | Flex Cup | Intimina Lily Cup | June Cup

🚨 Red Flags: Non-Cleared Cups

Avoid cups that:

  • Are sold on non-reputable sites (e.g., Amazon third-party sellers with no FDA info).

  • Claim "FDA Approved" (misleading term—they’re cleared).

  • Lack material details or list "proprietary silicone" (should specify medical-grade).

🌎 International Standards Matter Too

  • EU: Requires CE marking (similar rigor to FDA).

  • Canada: Health Canada license (e.g., DivaCup).

  • Australia: TGA approval.
    Reputable brands comply with global standards.

🩺 Gynecologist Perspective

"I recommend FDA-cleared cups because they guarantee material safety. But clearance doesn’t mean ‘risk-free’—follow hygiene protocols strictly."
— Dr. Jen Gunter, OB-GYN

💡 User Safety Checklist

  1. Buy direct from the brand or authorized retailers (Target, CVS).

  2. Sterilize before first use (boil 5-10 mins).

  3. Never exceed 12-hour wear.

  4. Inspect regularly for tears/discoloration.

🚫 The TSS Reality

  • All internal period products (cups, tampons, discs) carry TSS risk.

  • FDA-cleared cups have lower risk than tampons (non-absorbent material), but warnings are mandatory:

    "Leave in no longer than 12 hrs. See a doctor if you have fever, rash, or dizziness."

✅ The Bottom Line

Menstrual cups sold legally in the U.S. are FDA-cleared as safe Class II devices—but "clearance" isn’t a gold stamp of perfection. It guarantees:

  • Medical-grade materials

  • Basic biocompatibility

  • Honest labeling

Protect yourself:

  • ✔️ Verify FDA clearance before buying.

  • ✔️ Follow hygiene protocols religiously.

  • ✔️ Report cup-related injuries to the FDA MedWatch.

✨ Knowledge is power: Use the FDA database, read labels, and prioritize brands that transparently share their clearance status. Your health isn’t worth the $5 Amazon knockoff.
