title: Clinical safety assessment of an ultra absorbency menstrual tampon.
abstract: BACKGROUND
  Menstrual tampons are available in a range of absorbencies to allow women to use the product most appropriate to their needs. This study assessed the safety of an ultra absorbency (15 g to 18 g) tampon compared with a currently marketed super-plus absorbency (12 g to 15 g) tampon as a control.
  
  
  METHODS
  Healthy women age 18-45 years (n = 95) were enrolled in this single-blind, crossover study. Subjects used, in random order, the experimental tampon during one menstrual cycle and the control tampon during the other. Subjects were also randomly assigned to receive either vaginal microbial assessments for determination of the presence and density of Staphylococcus aureus (n = 35) or colposcopic examinations for assessment of changes in the vaginal mucosa (n = 60). Data on comfort and acceptability of the tampons were collected by using diaries and questionnaires completed by the subjects in both groups.
  
  
  RESULTS
  Twenty-eight women in the microbial assessment group and 43 in the colposcopic examination group completed the study; these subjects made up the primary analysis population. No differences in isolation frequency or cell density of S. aureus or in vaginal mucosal changes were observed with the experimental tampon in comparison with the control tampon. No reported adverse events were attributed to the experimental tampon. Both tampons received positive comfort ratings.
  
  
  CONCLUSIONS
  Based upon microbial assessments, colposcopic examinations, adverse events, and subject reporting of comfort, the ultra absorbency tampon is similar in safety profile to the currently marketed super plus absorbency tampon.
