One of the primary uses of chlorhexidine is for oral hygiene. It is often found in mouthwashes and toothpaste, as it effectively kills bacteria that can cause dental plaque, gum disease, and bad breath.

Chlorhexidine is also utilized as a surgical scrub or skin cleanser before medical procedures to prevent infections. It is known for its persistent and long-lasting antimicrobial activity, providing protection against a wide range of bacteria.

Furthermore, chlorhexidine is used for wound care to prevent infection and promote healing. It can be found in various formulations, such as gels, creams, and solutions, which are often applied topically.


The use of chlorhexidine has numerous benefits, thanks to its potent antimicrobial properties. Some of the key benefits include:

1. Effective against a wide range of bacteria: Chlorhexidine is highly effective against various types of bacteria, including both gram-positive and gram-negative bacteria. This makes it an invaluable tool in preventing and treating infections.

2. Long-lasting antimicrobial activity: Chlorhexidine has a persistent effect, providing a prolonged period of protection against bacteria. This makes it particularly useful in healthcare settings where maintaining a sterile environment is crucial.

4. Safety: Chlorhexidine is generally safe for use when used as directed. It does not typically cause systemic side effects, making it a reliable choice for a wide range of individuals.

Side Effects

While chlorhexidine is considered safe for most people, some individuals may experience side effects. These side effects are generally mild and may include:

1. Staining of teeth: Prolonged use of chlorhexidine mouthwashes or other chlorhexidine-containing oral care products may cause staining of teeth. This can usually be resolved through dental cleanings.

2. Discoloration of tongue: Some individuals may experience temporary discoloration of the tongue after using chlorhexidine-containing products. This effect is harmless and resolves on its own.

3. Skin irritation: Topical use of chlorhexidine may rarely cause skin irritation or allergic reactions in some individuals. Discontinue use if you experience any unusual symptoms.

It is important to note that serious allergic reactions to chlorhexidine are extremely rare but require immediate medical attention.

3. Avoid contact with eyes and ears: Chlorhexidine products should not come into contact with the eyes or ears, as it may cause irritation. In case of accidental contact, rinse thoroughly with water and seek medical advice if necessary.

4. Do not swallow chlorhexidine mouthwash: Chlorhexidine mouthwash is intended for gargling and spitting out, not for swallowing. Ingesting chlorhexidine can lead to serious side effects and should be avoided.
