You’re sitting in a high school health class, or maybe you're reading the back of a tampon box for the hundredth time, and there it is: the warning about Toxic Shock Syndrome (TSS). It sounds terrifying. It sounds like something out of a medical drama. Naturally, you start wondering about the alternatives. If tampons carry this risk, you might ask, can you get toxic shock syndrome from pads?
The short answer is: technically, yes, but it is incredibly, vanishingly rare.
It's one of those "medical technicality" situations. When we talk about TSS, we are almost always talking about internal products. Tampons. Menstrual cups. Diaphragms. But the biology of the bacteria involved doesn't strictly care about your choice of period product. It cares about oxygen, surface area, and time.
Why We Associate TSS With Tampons Anyway
To understand the risk with pads, you have to look at why tampons got the bad reputation in the first place. Back in the late 1970s and early 1980s, there was a massive spike in TSS cases. Most of them were linked to a specific brand called Rely. These tampons were super-absorbent—like, "stay in for days" absorbent.
They were made of synthetic materials like polyester foam and carboxymethylcellulose. These materials were too good at their jobs. They created a perfect playground for Staphylococcus aureus. This bacterium is actually a pretty common guest on human skin and in the vaginal canal. Usually, it's harmless. But when it finds a high-oxygen environment with plenty of "food" (blood), it can produce a toxin called TSST-1.
That toxin is the real villain. It triggers a massive inflammatory response. Your blood pressure drops. Your organs start to struggle. It’s a systemic wildfire.
Because pads are external, they don't usually create that "stagnant, oxygen-rich, internal" environment. They sit against the skin. They breathe—at least more than an internal plug does. This is why the medical community generally considers them the "safe" option for people worried about TSS.
The Freak Occurrences: Can You Get Toxic Shock Syndrome From Pads?
So, how does it happen with a pad? If you search medical databases like PubMed for "TSS and menstrual pads," you won't find much. Why? Because it almost never happens. However, "almost" isn't "never."

A case of TSS linked to a pad would usually involve a perfect storm of bad luck and hygiene. If a person has a pre-existing skin infection, a surgical wound, or a severe tear in the vulvar area, the Staph bacteria can colonize the pad. If that pad isn't changed for an extremely long time—we’re talking 24 hours or more—the bacteria could theoretically multiply to a point where toxins enter the bloodstream through the broken skin.
Dr. Jen Gunter, a noted OB/GYN and author of The Vagina Bible, has spent a lot of time debunking period myths. She often points out that TSS isn't actually a "tampon disease." It’s a bacterial toxin disease. You can get TSS from a skin burn. You can get it after surgery. Men get TSS. Children get TSS.
Honestly, the risk of getting TSS from a pad is likely no higher than the risk of getting it from a scraped knee that gets infected. It’s a different pathway. With a tampon, the product is the delivery mechanism for the environment the bacteria love. With a pad, the pad is just a surface that happens to be there while an infection takes hold elsewhere.
Symptoms That Actually Matter
Whether you use pads, tampons, or a cup, you need to know what the red flags look like. TSS moves fast. It’s not a "wait and see" kind of illness.
- The Sudden Fever. We aren't talking about a low-grade 99-degree sniffle. This is a "hit you like a truck" 102°F or higher fever that appears out of nowhere.
- The Sunburn Rash. A flat, red rash that looks like you spent too long at the beach without SPF. It often shows up on the palms of the hands and soles of the feet.
- The "Ghost" Fainting. Your blood pressure tanks. You might feel incredibly dizzy when you stand up, or you might actually pass out.
- Vomiting or Diarrhea. Your body is trying to purge the toxins. It's often mistaken for the flu or food poisoning, but when paired with a period, it should raise an eyebrow.
If you have these symptoms and you're on your period, it doesn't matter if you're wearing a pad or a tampon. Go to the ER. Tell them you’re menstruating. Don't worry about sounding paranoid. Doctors would much rather rule out TSS than treat a patient who waited too long.
Let’s Talk About Modern Pads
Pads have changed a lot since the 80s. Most are now made of cotton, rayon, or a blend of wood pulp and "super-absorbent polymers" (SAPs). SAPs are those tiny beads that turn liquid into gel.
There was some internet panic a few years ago claiming that the chemicals in pads—like dioxins or bleaches—could cause TSS or cancer. The FDA actually regulates these products pretty strictly. While there are trace amounts of chemicals used in the bleaching process (elemental chlorine-free), they are generally below the level of detection.

The real risk with pads isn't TSS. It’s contact dermatitis.
Some people are sensitive to the fragrances or the plastic-like top sheets on certain brands. This causes itching, redness, and misery. It’s not life-threatening like TSS, but it’s definitely not a good time. If you’re worried about the "safety" of your pads, switching to an unscented, organic cotton version is usually a better move for your skin health than for TSS prevention.
Breaking Down the "Tampon Fear"
A lot of the anxiety around can you get toxic shock syndrome from pads comes from a place of wanting to be perfectly safe. We live in an era of "wellness" where we're told everything is trying to kill us.
But let’s look at the numbers. The CDC notes that the incidence of TSS is roughly 0.8 to 3.4 per 100,000 people. That is incredibly low. To put that in perspective, you're statistically more likely to be struck by lightning in your lifetime than to get TSS in a given year.
Because we’ve moved away from the hyper-synthetic materials of the 80s and improved manufacturing standards, the "tampon plague" is largely a thing of the past. Yes, it still happens. Yes, it is serious. But it isn't the looming shadow it once was. Using a pad virtually eliminates the "internal cultivation" risk factor, making your chances of period-related TSS effectively zero, provided you aren't leaving the same pad on for days at a time.
Hygiene Realities vs. Medical Myths
Is it gross to leave a pad on for 12 hours? Maybe. Is it going to give you TSS? Probably not.
The main reason doctors tell you to change your pad every 4 to 8 hours isn't to prevent a deadly blood infection. It’s to prevent odor and irritation. Blood is organic material. When it sits at body temperature, exposed to air, bacteria start to break it down. That’s where the "period smell" comes from. It's also how you get a "diaper rash" situation from the moisture sitting against your skin.

If you’re someone with a very heavy flow, you’re changing it often anyway. If you have a light flow, you might be tempted to let it ride all day. Just... don't. Your skin will thank you.
What about "Period Underwear"?
The rise of brands like Thinx or Knix has introduced a new variable. Period underwear is basically a giant, wearable pad. People ask the same question: can these cause TSS?
Again, the risk is external. Unless you have an open wound in the "saddle area" and you're wearing blood-soaked underwear for 24+ hours, you're fine. The fabrics used in these garments are often treated with antimicrobial finishes (like silver or copper) specifically to stop bacterial growth and odor.
The Bottom Line on Safety
You can breathe easy. If you prefer pads because you're scared of TSS, your logic is sound. Pads are the safest menstrual product when it comes to the risk of Staphylococcus toxin production.
Could a medical textbook find a way to link a pad to a case of TSS? Sure. Doctors have seen everything. But in the real world, for the average person, it’s just not a thing.
The history of women's health is full of half-truths and "scare-lore." We spent decades being told tampons would ruin our virginity or that pads were "unsanitary." TSS is one of the few fears that actually had a basis in a real-world product failure (the Rely tampon). But that failure led to the safety standards we have today.
Actionable Steps for Peace of Mind
- Change your pad every 4-8 hours. Even if it’s not "full," the fresh air is good for your skin and keeps bacteria levels low.
- Wash your hands. This is the most underrated advice ever. Most bacteria get onto the pad or tampon from your hands during the changing process. Wash before and after.
- Choose the right absorbency. Don't wear a "Heavy/Overnight" pad for a tiny bit of spotting. Use what you need for the flow you have.
- Track your symptoms. If you ever feel "flu-ish" during your period—especially if you've been using internal products—take your temperature. Knowledge is power.
- Don't stress the "chemicals." If your pad doesn't irritate your skin, it’s likely not doing you any harm. If it does itch, go fragrance-free.
The fear of TSS shouldn't run your life. Use the products that make you feel comfortable and clean. If that’s a pad, you’ve already picked the option with the lowest possible risk profile. Stop worrying about the rare "what ifs" and just keep up with basic hygiene. You’re doing fine.
