Rely was a brand of superabsorbent tampon
Tampon
A tampon is a mass of cotton or rayon or a mixture of the two inserted into a body cavity or wound to absorb bodilyfluid. The most common type in daily use is designed to be inserted into the vagina during menstruation to absorb the flow of menstrual fluid...

.

Following a controversial period of test marketing in Rochester and Fort Wayne, in August 1978 Procter and Gamble introduced superabsorbent Rely tampons to the United States market in response to women's demands for tampons that could absorb more menstrual flow without leaking or replacement.

Unlike other tampons, which are made with cotton

Further, the tampon would "blossom" into a cup shape in the vagina
Vagina
The vagina is a fibromuscular tubular tract leading from the uterus to the exterior of the body in female placental mammals and marsupials, or to the cloaca in female birds, monotremes, and some reptiles. Female insects and other invertebrates also have a vagina, which is the terminal part of the...

 in order to hold menstrual fluids. Because of this, its advertising slogan was "It even absorbs the worry!", and claimed it could hold up longer than the leading tampon, because it was made differently. "Remember, They named it Rely" was the last line of most commercials.

The superabsorbent properties of Rely caused vaginal dryness by absorbing the natural humidity
Humidity
Humidity is a term for the amount of water vapor in the air, and can refer to any one of several measurements of humidity. Formally, humid air is not "moist air" but a mixture of water vapor and other constituents of air, and humidity is defined in terms of the water content of this mixture,...

 to infect the bloodstream. Further, the tampons' superabsorbency meant that the viscosity of vaginal fluids was enhanced, providing a good environment for bacteria growth. In addition, carboxymethylcellulose has features which effectively filter the toxins of Staphylococcus which cause TSS.

Procter and Gamble recalled Rely in September 1980 after the Centers for Disease Control released a report that summer, explaining the bacterial mechanism which lead to TSS, and that Rely tampons were associated with TSS more than any other tampon. As part of the voluntary recall, Procter and Gamble entered into a consent agreement with the Food & Drug Administration "providing for a program for notification to consumers and retrieval of the product from the market". The recall cost Procter and Gamble over USD

75 million.

One very important effect of the attention to TSS in the 1980s was that the FDA implemented regulation of tampons as medical devices and forced manufacturers to standardize tampon absorbencies and include package inserts that warn tampon users of TSS risk. On the market today are tampons made both from synthetic materials, especially rayon, and from cotton only. The key ingredients used in Rely, carboxymethylcellulose and polyester, were removed from the market in 1980.

Reported cases of TSS have decreased dramatically since the 1980s.
