Manufacturers of tampons sold in the United States no longer use the materials or designs that were associated with toxic shock syndrome. Also, the Food and Drug Administration requires manufacturers to use standard measurement and labeling for absorbency and to print guidelines on the boxes.
If you use tampons, read the labels and use the lowest absorbency tampon you can. Change tampons frequently, at least every four to eight hours. Alternate using tampons and sanitary napkins, and use minipads when your flow is light.
Toxic shock syndrome can recur. People who've had it once can get it again. If you've had toxic shock syndrome or a prior serious staph or strep infection, don't use tampons.
