A recent study from the University of California-Davis has prompted a warning about hand sanitizers and what can happen when too much is used. According to researchers, sanitizers that contain triclosan can cause muscle weakness if used in excess.

Although triclosan was first developed to prevent bacterial infections in hospitals, its use has become widespread in antibacterial products such as hand soaps, deodorants, mouthwashes, toothpaste, bedding, clothes, carpets, toys and trash bags.

The Food and Drug Administration, which for years has said triclosan doesn't pose a danger to people, is now in the process of reviewing that stance. FDA scientists have said that washing hands with regular soap is just as effective as using antibacterial soaps.

The study appears at the Proceedings of the National Academy of Sciences of the United States of America website here.
