Rely tampon

1978-1980

Procter & Gamble introduced this super absorbent tampon with the slogan “it even absorbs the worry”. Little did they know that their product would cause a whole lot more than just worry. Rely was made with a new highly absorbent material: carboxymethyl-cellulose and polyester. This was a failure of safety. Women were leaving tampons in for much longer periods of time, which could cause a deadly bacterial infection called: Toxic Shock Syndrome. Rely tampons became associated with death and illness, and were quickly discontinued.
