Do Menstrual Cups Cause Toxic Shock Syndrome (TSS)?

Menstrual cups have gained popularity as a sustainable, cost-effective, and comfortable alternative to traditional menstrual products. However, concerns about the risk of Toxic Shock Syndrome (TSS) often arise when discussing menstrual cup usage. In this blog post, we will delve into the question: Do menstrual cups cause Toxic Shock Syndrome? Let’s unravel the facts, dispel the myths, and explore the role menstrual cup users can play in reducing their risk of TSS.

Understanding Toxic Shock Syndrome (TSS)

Toxic Shock Syndrome is a rare but serious and potentially life-threatening condition caused by bacterial toxins. It is often associated with the use of highly absorbent tampons. TSS can occur when certain strains of Staphylococcus aureus (Staph) or Streptococcus pyogenes (Strep) bacteria produce toxins that enter the bloodstream and lead to systemic effects.

Menstrual Cups and TSS: The Facts

Lower Risk than Tampons

Studies suggest that the risk of TSS associated with menstrual cup usage is significantly lower compared to the risk associated with the use of high-absorbency tampons. This is because menstrual cups collect menstrual blood rather than absorbing it, helping to maintain a more balanced vaginal environment.

Proper Usage and Hygiene

To reduce the risk of TSS and maintain overall menstrual health, it is crucial to follow proper usage and hygiene guidelines. This includes washing your hands before and after inserting or removing the menstrual cup, emptying and cleaning the cup regularly, and sterilizing the cup between menstrual cycles as recommended by the manufacturer.

Duration of Use

Unlike tampons, which require frequent changing to prevent bacterial growth, menstrual cups can typically be safely worn for up to 12 hours without increasing the risk of TSS. However, individual variations and flow may necessitate more frequent emptying and cleaning.

Reducing the Risk of TSS

Sterilization Techniques

Proper sterilization of the menstrual cup is essential to maintain cleanliness and minimize the risk of bacterial growth. This typically involves boiling the menstrual cup in water for a recommended duration before the start of each menstrual cycle. Always refer to the manufacturer’s guidelines for specific sterilization instructions.

Regular Cleaning

Menstrual cups should be thoroughly cleaned with mild, unperfumed soap or a specific menstrual cup cleanser after each use. Avoid using harsh chemicals or scented products that may cause irritation or disrupt the vaginal flora.

Vaginal Microbiome Balance

Maintaining a healthy vaginal environment is crucial in reducing the risk of TSS. Avoid using douches, fragranced products, or harsh soaps, as they can disrupt the natural balance of the vaginal microbiome, potentially increasing vulnerability to infections.

Awareness and Monitoring

Being aware of the signs and symptoms of TSS is essential for prompt identification and treatment. Symptoms may include high fever, rash, low blood pressure, vomiting, and diarrhea. If you experience any of these symptoms while using a menstrual cup, seek medical assistance immediately.


Contrary to popular misconceptions, menstrual cups do not significantly increase the risk of Toxic Shock Syndrome. With proper usage, hygiene, and awareness of the signs and symptoms of TSS, menstrual cup users can confidently enjoy the benefits of this eco-friendly and sustainable menstrual care option.

Remember to always follow the manufacturer’s instructions for sterilization, cleaning, and duration of use. Regularly monitor your menstrual cup for any signs of wear or damage and replace it as necessary. Stay informed about menstrual cup usage and engage in open conversations with healthcare professionals to address any concerns.

By maintaining good menstrual hygiene practices, respecting your body’s unique needs, and being mindful of any potential symptoms of TSS, you can safely embrace the convenience and eco-friendliness of menstrual cups as a reliable period care option.
