Prescribing considerations

• Confirm that the injury is minor and superficial; this preparation does not replace debridement, closure, systemic treatment or burn assessment when indicated.
• Reassess spreading redness, increasing pain, heat, swelling, pus, fever or failure to improve.
• For burns, prioritise immediate cooling and severity assessment before topical treatment.

Contraindications and cautions

• Do not use as sole management for large, deep, electrical or chemical burns.

Monitoring

• No routine laboratory monitoring is required.
• Monitor local tolerability and the wound for deterioration or infection.

Clinical pharmacology

Cetrimide is a quaternary ammonium antiseptic that damages microbial membranes. The combination adds the local antiseptic activity of 2,4-dichlorobenzyl alcohol and allantoin as a skin-conditioning and repair-supporting component.

Formulation and product differences

• The product is a topical cream containing all three active ingredients.
• The cream base includes cetostearyl alcohol, paraffin components, dimeticone and perfume; consider excipient sensitivity in people with previous contact reactions.
