Hibiwash (Chlorhexidine Digluconate Solution)

Hibiwash is used as an external antiseptic for a variety of skin‑related procedures. It is commonly applied in clinical and home settings where microbial control is required.

• Skin antisepsis before minor surgical or invasive procedures.
• Cleaning of superficial wounds, cuts, and abrasions.
• Preparation of the skin prior to insertion of catheters or IV lines.
• Disinfection of intact skin before injections or blood draws.
• Reducing bacterial colonization on hands of healthcare workers when used as a hand‑rub.

• Chlorhexidine digluconate exerts its antiseptic activity by binding to negatively charged bacterial cell walls and disrupting membrane integrity. The cationic molecule penetrates the lipid bilayer, causing leakage of intracellular contents and precipitation of cytoplasmic proteins. This leads to rapid bactericidal effects against a broad spectrum of Gram‑positive and Gram‑negative organisms, as well as some fungi and viruses, and contributes to sustained antimicrobial activity on the skin surface.

Adverse reactions to Hibiwash are generally limited to local skin responses, although rare systemic effects have been reported.

Common

• Mild skin irritation or erythema at the application site.
• Transient itching or burning sensation.
• Dryness or peeling of the treated skin.
• Temporary discoloration of the skin that resolves spontaneously.
• Localized swelling or edema.
• Mild pain at the site of application.

Serious

• Allergic contact dermatitis with vesicles, intense redness, or swelling.
• Anaphylactic reaction with difficulty breathing, facial or throat swelling, and hypotension.
• Rare cases of severe skin necrosis at the treated area.

When using Hibiwash, certain precautions help minimize the risk of irritation and ensure safe application.

• Do not apply to mucous membranes, eyes, or internal body cavities.
• Avoid use on large open wounds, burns, or compromised skin unless directed by a healthcare professional.
• Test a small skin area first to assess for hypersensitivity before broader application.
• Keep the solution away from children; store out of reach and at room temperature.
• Discontinue use and seek medical advice if signs of allergic reaction develop.
• Do not use on patients with known hypersensitivity to chlorhexidine or related compounds.
• Use only as directed; do not exceed the recommended amount.

Chlorhexidine can interact with certain substances, which may affect its efficacy or increase the risk of adverse reactions.

Avoid

• Concurrent use with ototoxic drugs (e.g., aminoglycoside ear drops) in the ear.
• Application on skin pre‑treated with iodine‑based antiseptics, which may reduce antimicrobial activity.
• Use together with strong acids or alkalis that can inactivate chlorhexidine.

Use with caution

• Simultaneous use with other topical antiseptics; monitor for increased skin irritation.
• Use in patients receiving systemic antibiotics; assess for potential additive antimicrobial effects.
• Application on devices or dressings containing latex; watch for latex‑chlorhexidine reactions.
