Hexomedine Transdermique (Hexamidine Diisetionate)

Hexomedine Transdermique is indicated for external antiseptic use on the skin, particularly when a broad‑spectrum antimicrobial action is desired to help prevent bacterial colonisation.

• Cleansing and disinfecting minor cuts, abrasions, or superficial lacerations before they are dressed.
• Preparing the skin surface prior to minor surgical or diagnostic procedures to reduce microbial load.
• Reducing the risk of infection in superficial wounds such as blisters, burns, or skin tears.
• Antiseptic pre‑treatment of the skin before insertion of small medical devices, for example peripheral IV catheters.
• Routine skin antisepsis in areas prone to irritation or moisture, such as intertriginous zones.

• Hexamidine diisetionate is a bisbiguanide antiseptic that exerts its antimicrobial effect by binding to bacterial cell membranes and intracellular proteins, disrupting membrane integrity and increasing permeability. This leads to leakage of cellular contents and inhibition of essential enzymatic processes, ultimately resulting in bacterial cell death across a broad spectrum of Gram‑positive and Gram‑negative organisms.

Adverse reactions to Hexomedine Transdermique are generally uncommon, but they can occur following topical application.

Common

• Mild erythema or redness at the application site, usually transient.
• Slight itching or pruritus that resolves within a few hours.
• Minor skin dryness or peeling in the treated area.
• Transient burning or stinging sensation immediately after application.

Serious

• Localized severe allergic dermatitis with swelling, requiring medical evaluation.
• Contact urticaria or angio‑edema that may extend beyond the application area.
• Rare systemic hypersensitivity reaction such as anaphylaxis, necessitating emergency care.

When using Hexomedine Transdermique, certain precautions help ensure safe and effective application.

• Avoid applying to broken, severely damaged, or deep wounds without medical advice.
• Do not use on mucous membranes, eyes, or genital mucosa.
• Discontinue use if signs of irritation or allergic reaction develop.
• Keep the product out of reach of children; store at room temperature away from direct sunlight.
• Do not cover the treated area with occlusive dressings unless directed by a healthcare professional.
• Consult a physician before use in individuals with known sensitivity to biguanide antiseptics.

Topical hexamidine may interact with certain substances; awareness of these interactions can prevent reduced efficacy or irritation.

Avoid

• Avoid concurrent use with other topical antiseptics containing alcohol or iodine, which may increase skin irritation.
• Do not apply on skin pre‑treated with strong keratolytic agents (e.g., salicylic acid) without professional guidance.

Use with caution

• Use with caution when combined with topical corticosteroids, as they may mask signs of irritation.
• Caution is advised when applying near wound dressings containing silver or chlorhexidine, as additive antimicrobial effects may cause local irritation.
• Patients using other skin‑care products containing fragrances or preservatives should monitor for additive allergic responses.
