Curator's Comment: Description was created based on several sources, including: http://www.accessdata.fda.gov/drugsatfda_docs/label/2013/019028s022lbl.pdf http://www.drugbank.ca/drugs/DB00878 http://www.wikidoc.org/index.php/Chlorhexidine_gluconate

Chlorhexidine is a broad-spectrum biocide effective against Gram-positive bacteria, Gram-negative bacteria and fungi. It is used primarily as its salts (e.g., the dihydrochloride, diacetate, and digluconate). Chlorhexidine inactivates microorganisms with a broader spectrum than other antimicrobials (e.g. antibiotics) and has a quicker kill rate than other antimicrobials (e.g. povidone-iodine). It has both bacteriostatic (inhibits bacterial growth) and bactericidal (kills bacteria) mechanisms of action, depending on its concentration. Chlorhexidine kills by disrupting the cell membrane. The most common side effects associated with chlorhexidine gluconate oral rinses are: 1) an increase in staining of teeth and other oral surfaces; 2) an increase in calculus formation; and 3) an alteration in taste perception; 4) toothache; 5) upper respiratory tract infection; and 6) headache.
