- Increased risk for menstrual toxic shock syndrome (MTSS) is associated with >6 hours of consecutive tampon use and overnight tampon use.
Why this matters
- MTSS is an uncommon but life-threatening illness associated with the use of vaginal tampons and other intravaginal devices.
- Improved education may decrease the risk for MTSS.
- 55% met criteria for diagnosis of MTSS and 45% for probable MTSS.
- Increased MTSS risk was associated with:
- >6 hours of consecutive tampon use: OR, 2.33 (95% CI, 1.21-4.47); and
- Overnight tampon use: OR, 3.22 (95% CI, 1.37-7.69).
- Nationwide case-control study in France.
- 55 women and girls ages 12-30 years with a clinical diagnosis of MTSS who were reported to the French National Centre for Scientific Research between 2011 and 2017 were identified and compared with a control group (n=126).
- Main exposure was tampon use.
- Funding: Université de Lyon and the French National Research Agency.
- MTSS is a rare condition.
