How easy is it to get TSS?

Understanding the Risk of Toxic Shock Syndrome

Toxic shock syndrome (TSS) sounds alarming—and it is serious—but it’s important to remember that it’s extremely rare. Most people hear about TSS in relation to menstruation, especially tampon use, but the truth is, catching it is uncommon. Still, knowing how it happens can help you stay safe.

TSS is caused by bacteria, most often Staphylococcus aureus, which can produce toxins under certain conditions. While rare, it’s possible to develop TSS from using tampons, especially if they’re left in too long. The same goes for menstrual cups, diaphragms, or cervical caps used for contraception. These devices, when left in place for extended periods, can create an environment where bacteria multiply and release dangerous toxins.

The good news is that simple habits greatly reduce the risk. Changing tampons every four to eight hours, using the lowest absorbency needed, and alternating with pads can make a big difference. If you use a menstrual cup, follow the instructions carefully—empty it regularly and clean it properly. For diaphragms or caps, never leave them in longer than recommended, usually no more than 30 hours.

Symptoms of TSS can come on quickly: high fever, vomiting, diarrhea, dizziness, a sunburn-like rash, or confusion. If these occur during or right after your period—especially with tampon or cup use—it’s crucial to act fast. Remove the device and seek medical help immediately. Early treatment is key.

While TSS can be life-threatening, awareness and good hygiene go a long way in preventing it. Millions of people use tampons and other menstrual products safely every day. With a little knowledge and care, the risk remains very low.
