Safety Warning Tampons are associated with Toxic Shock Syndrome (TSS). TSS is a rare but serious disease that may cause death. Read and save the enclosed information. Tampons come in standardized industry-wide absorbencies. Use the chart for comparing absorbencies of all industry products. The risk of toxic shock syndrome (TSS) increases with higher absorbency. In order to reduce your risk of TSS, you should use the lowest absorbency that meets your needs.
