Hibiscrub (Chlorhexidine Gluconate)

Hibiscrub is indicated for a range of skin antisepsis applications in both healthcare and non‑healthcare environments.

• Pre‑operative skin preparation to reduce microbial load before surgical incision.
• Hand hygiene for healthcare workers and the public, especially when soap and water are unavailable.
• Cleaning of minor cuts, abrasions, and superficial wounds to prevent infection.
• Disinfection of intact skin prior to invasive procedures such as catheter insertion or venipuncture.
• Environmental skin decontamination in settings like dialysis units or intensive care areas.

• Chlorhexidine gluconate exerts its antiseptic effect 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 loss of essential cellular components leads to rapid bactericidal activity against a broad spectrum of Gram‑positive and Gram‑negative organisms, as well as some fungi and viruses.

Adverse reactions to Hibiscrub are generally limited to 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 stinging sensation that resolves within minutes.

Serious

• Allergic contact dermatitis characterized by intense redness, swelling, and vesicle formation.
• Severe hypersensitivity reactions such as anaphylaxis, though extremely rare.
• Chemical burns with prolonged exposure or use on compromised skin.
• Persistent discoloration of the skin, especially with repeated use.
• Systemic toxicity such as hypotension or renal impairment is exceedingly rare but reported.

When using Hibiscrub, several precautionary measures help minimize irritation and ensure safe application.

• Avoid applying to mucous membranes, eyes, or open wounds unless specifically indicated.
• Do not use on damaged, inflamed, or excessively moist skin without professional guidance.
• Limit exposure time; rinse thoroughly with water after the recommended contact period.
• Keep the product out of reach of children and store at room temperature, away from direct sunlight.
• Discontinue use and seek medical advice if signs of allergic reaction develop.
• Do not combine with other topical antiseptics containing alcohol or iodine without consulting a healthcare professional.

Hibiscrub may interact with certain topical agents or systemic conditions, requiring attention to avoid reduced efficacy or increased irritation.

Avoid

• Concurrent use with other chlorhexidine‑containing products, which can increase skin irritation.
• Application over products that contain alcohol, peroxide, or iodine, as chemical incompatibility may diminish antiseptic activity.
• Use on patients with known hypersensitivity to chlorhexidine or related compounds.

Use with caution

• Co‑administration with occlusive dressings, which may trap the solution and enhance local irritation.
• Use in patients with renal impairment when large amounts are absorbed, although systemic absorption is minimal.
• Application before procedures involving high‑concentration antiseptics, ensuring adequate rinsing to prevent additive toxicity.
