Hibiscrub (Chlorhexidine Gluconate)

Hibiscrub is indicated for several external antiseptic applications where reduction of skin‑borne microorganisms is desired.

• Pre‑operative skin antisepsis before surgical or invasive procedures.
• Cleansing of minor cuts, abrasions, and lacerations to prevent infection.
• Hand hygiene for health‑care workers and patients when soap and water are unavailable.
• Disinfection of intact skin prior to catheter or needle insertion.
• Surface cleaning of non‑porous medical equipment in clinical settings.
• Preparation of skin for the application of topical medications or dressings.

• Chlorhexidine gluconate exerts its antiseptic effect by binding to negatively charged bacterial cell walls and disrupting membrane integrity. The cationic molecules insert into the lipid bilayer, increasing permeability and causing leakage of intracellular contents. This loss of essential ions and metabolites leads to rapid bacterial cell death, affecting a broad spectrum of Gram‑positive and Gram‑negative organisms. The action is concentration‑dependent and persists for several hours after application.

Topical application of Hibiscrub may be associated with local skin reactions, most of which are mild, transient, and resolve without treatment.

Common

• Mild erythema or redness at the application site.
• Transient itching or burning sensation.
• Dryness or peeling of the skin.
• Localized swelling or edema.
• Temporary discoloration of the skin.
• Slight stinging sensation upon first use.
• Minor scaling after repeated applications.

Serious

• Allergic contact dermatitis with swelling and vesicle formation.
• Severe skin irritation leading to ulceration.
• Systemic hypersensitivity reactions such as urticaria or anaphylaxis (rare).
• Persistent or worsening irritation that does not resolve with washing.

When using Hibiscrub, certain precautions help minimize adverse reactions and ensure safe application.

• Avoid application on mucous membranes, eyes, or broken skin beyond minor abrasions.
• Perform a small patch test on intact skin before widespread use, especially in individuals with a history of skin sensitivity.
• Do not cover the treated area with occlusive dressings unless directed by a healthcare professional.
• Keep the product out of reach of children; accidental ingestion may cause gastrointestinal irritation.
• Store at room temperature, protected from direct sunlight and moisture.
• Discontinue use and seek medical advice if signs of an allergic reaction develop.

Hibiscrub can interact with certain topical agents or systemic conditions; awareness of these interactions helps prevent reduced efficacy or increased irritation.

Avoid

• Avoid simultaneous use with other antiseptic solutions containing alcohol or iodine, which may increase skin irritation.
• Do not combine with topical corticosteroids immediately after application, as steroids can diminish the antiseptic effect.

Use with caution

• Use with caution on patients with known hypersensitivity to chlorhexidine or related compounds.
• Caution is advised when applying to extensive skin areas in neonates or infants, due to higher absorption risk.
• When used on surgical sites, ensure adequate rinsing before closure to prevent residual antiseptic affecting wound healing.
