Side effects may include skin irritation, tooth discoloration, and allergic reactions, although the risk appears to be the same as other topical antiseptics. Chlorhexidine rinse is also known to have a bitter metallic aftertaste. Rinsing with water is not recommended as it is known to increase the bitterness. It may cause eye problems if direct contact occurs. Use in pregnancy appears to be safe. Chlorhexidine may come mixed in alcohol, water, or surfactant solution. It is effective against a range of microorganisms, but does not inactivate spores.

Chlorhexidine came into medical use in the 1950s. Chlorhexidine is available over the counter in the United States. It is on the World Health Organization's List of Essential Medicines. In 2020, it was the 273rd most commonly prescribed medication in the United States, with more than 1 million prescriptions.
