But studies show that these antibiotic chemicals are no more likely than regular soap to prevent gastrointestinal or respiratory illness. In fact, for chronically sick patients, antibiotic soaps were actually associated with increases in the frequencies of fevers, runny noses and coughs.
According to Scientific American:
"What we do know is that the influence of these wipes and salves does not end with our hands, but instead spreads from them down our drains and out into society.
What happens when antibiotic soaps and suds go down drains? To find out, a group of scientists recently made artificial drains clogged with bacteria ... and then subjected them to low and high doses of triclosan ... Triclosan kills 'weak' bacteria but favors the tolerant, among them species of bacteria that eat triclosan ... Triclosan may also favor lineages of bacteria that are also resistant to the oral antibiotics used in hospitals".
Additionally, there have been recent concerns about its possible effects on human health -- and triclosan has been detected in human breast milk, blood, and urine samples. A study evaluated the effects of triclosan in female rats, and was found to advance the age at which the rats hit puberty. Serum thyroid hormone concentrations were also suppressed by triclosan.
According to the study, published in Toxicological Sciences:
"In conclusion, triclosan affected estrogen-mediated responses in the pubertal and weanling female rat and also suppressed thyroid hormone in both studies."
