Toxic Shock Syndrome (TSS): What You Need to Know About Menstrual Products & Your Safety

Let’s talk about something no one really wants to think about—but absolutely should: Toxic Shock Syndrome (TSS).

If you’ve ever read the tiny warning slip in your tampon box and wondered, is this actually something to worry about?, the short answer is: yes—but it's rare, and preventable.

Here at Crimson Organic, we're committed to period care that puts your health first. That means being real about the risks—and helping you make safer, smarter choices.

So, What Exactly Is TSS?

TSS is a rare but serious illness caused by toxins produced by certain bacteria—most often Staphylococcus aureus. It can enter the bloodstream, causing rapid symptoms like fever, rash, confusion, low blood pressure, and even organ failure if untreated.

While TSS can affect anyone (including men and children), it's been most famously linked to tampon use. It is a common misconception that TSS is only tampon related though there are some improper usage factors that contribute to an increased risk. Here we break down TSS, what to know about the causes and how to reduce risk (especially if you are a tampon user).

What Causes TSS?

TSS doesn’t happen randomly—it requires a perfect storm of conditions:

• 🦠 Bacterial colonization (S. aureus)
• 🩸 Tampons or internal products that retain blood and allow bacteria to multiply
• 💧 Changes in vaginal pH, often caused by blood and synthetic materials
• ⏰ Prolonged wear time (typically over 8 hours)
• 🧬 Lack of antibodies to TSST-1 toxin (some younger menstruators don’t have them yet)

The environment inside the vagina during menstruation becomes more neutral in pH (6.5–8.0), which is exactly where these bacteria thrive. Add in a super-absorbent tampon made from synthetic materials that traps oxygen, and you’ve got the ideal conditions for TSS toxin production.

Are All Tampons Equal in Risk?

Not even close. Here’s where it gets important: not all tampons are made the same, and materials matter.

Conventional Tampons

Often made with rayon, synthetic blends, and bleached with chlorine, these tampons can:

• Bind bacteria more readily
• Retain more blood and moisture
• Disrupt the vagina’s natural microbiome
• Irritate the vaginal lining, creating micro-tears

All of which can increase the risk of TSS.

A key study found that synthetic fibers bind S. aureus and TSST-1 more readily than cotton does.

Why Organic Cotton Tampons Carry Less Risk

Our Crimson Organic tampons, are made from 100% GOTS-certified organic cotton, and here’s why that matters:

✅ 1. They’re breathable and natural

Organic cotton doesn’t trap moisture or oxygen the way synthetic fibers do, making it less hospitable to bacteria.

✅ 2. No chlorine bleach or synthetic residues

We use hydrogen peroxide bleaching—a safer, eco-friendly method that leaves no dioxins or toxins behind.

✅ 3. Dermatologically and microbiologically tested

Crimson tampons have been tested to not support S. aureus growth and not increase TSST-1 production—key markers of tampon safety.

✅ 4. Respectful of your vaginal flora

Certified organic tampons don’t interfere with the body’s Lactobacillus-based microbiome, which keeps your pH balanced and your body protected.

Can You Get TSS from Other Period Products?

Yes—but the risk is much lower:

🩸 Menstrual Cups & Discs

Rare cases have been reported, often due to improper sterilization or prolonged wear. Always wash and boil your cup between cycles, and don’t exceed 12-hour wear.

🩸 Reusable Pads & Period Underwear

These carry virtually no risk of TSS, as they’re worn externally. The only risk comes from poor hygiene—always wash thoroughly and wear clean products.

How to Reduce Your Risk of TSS from a tampon

• ⏰ Never wear a tampon longer than 8 hours
• 🩸 Use the lowest absorbency you need
• 🙌 Wash your hands before inserting any product
• 🌿 Choose organic cotton over synthetics
• 🚨 Know the symptoms: sudden fever, rash, vomiting, muscle aches, confusion
• 🧠 If something feels off—remove the product and seek medical attention immediately
