Chlorhexidine – history, mechanism and risks

Chlorhexidine, one of the most frequently prescribed medications, belongs to a group of medicines called antiseptic antibacterial agents. It is indicated as a mouthwash in the treatment of gingivitis, as it cleans the skin after injury and can be used to clean hands before a procedure. Chlorhexidine works by killing or preventing the growth of bacteria on the mucosa or skin. It should not be used in individuals who are known to be hypersensitive to Chlorhexidine gluconate or other ingredients. It may cause some reversible tooth discoloration or an increase in tartar formation.
