Hibiwash

Hibiwash is a topical antiseptic solution that contains chlorhexidine digluconate as its active ingredient, supplied as a liquid preparation for external use. Marketed in the European Union as an over‑the‑counter (OTC) product, Hibiwash is intended for skin antisepsis, pre‑operative skin preparation, and wound cleansing, providing broad‑spectrum antimicrobial activity. It is classified as an antiseptic/disinfectant and is commonly and widely used in both clinical and home settings.

Hibiwash is used as a topical antiseptic for a range of external applications where reduction of bacterial, fungal, and viral contamination is desired.

- Skin antisepsis prior to minor surgical or diagnostic procedures to lower infection risk. - Pre‑operative skin preparation on the surgical site to achieve a broad‑spectrum antimicrobial effect. - Cleansing of superficial wounds, abrasions, or cuts to prevent microbial colonisation. - Disinfection of intact skin before insertion of peripheral catheters, IV lines, or other invasive devices. - Hand and forearm decontamination for healthcare personnel performing aseptic techniques.

Topical application of chlorhexidine may be associated with local reactions, most of which are mild and reversible.

Common: - Transient stinging or burning sensation at the application site. - Mild erythema or redness of the skin. - Pruritus (itching) localized to the treated area. - Dryness or peeling of the skin. - Slight swelling or edema of the treated area. - Temporary discoloration or brown staining of the skin.

Serious: - Contact dermatitis with vesiculation or swelling. - Severe allergic reaction (e.g., urticaria, angioedema). - Chemical burns in cases of prolonged exposure or high concentration. - Systemic toxicity is extremely rare but may present with hypotension or arrhythmia. - Anaphylaxis with respiratory distress. - Severe mucosal irritation if applied to eyes or mucous membranes.

When using Hibiwash, certain precautions should be observed to minimise adverse reactions and ensure safe application.

- Avoid application on damaged, broken, or mucous membranes unless directed by a healthcare professional. - Do not use on patients with known hypersensitivity to chlorhexidine or related compounds. - Keep the solution away from eyes; if accidental contact occurs, rinse thoroughly with water. - Limit exposure time on intact skin to the duration recommended on the product label. - Do not apply to large surface areas or use under occlusive dressings without professional guidance. - Store at room temperature, away from direct sunlight and out of reach of children.

Chlorhexidine may interact with certain substances or medical conditions; consider the following guidance when combining Hibiwash with other agents.

Avoid: - Avoid simultaneous use with anionic surfactants (e.g., soaps containing sodium lauryl sulfate) as they can lower efficacy. - Do not combine with topical iodine preparations, which may cause precipitation and reduce antimicrobial activity. - Avoid use on skin pre‑treated with alcohol‑based hand rubs immediately before application, as this may increase irritation.

Use with caution: - Use with caution in patients with thyroid disorders when applying to large areas, as systemic absorption can occur. - Caution is advised when applying near catheters or prosthetic implants; monitor for possible biofilm formation. - Use carefully in individuals with a history of antiseptic allergy; consider a patch test if uncertain.
