It combines three antibiotics with different antibacterial actions, providing activity against a range of susceptible bacteria. This medicine is generally intended for **external use on the skin** and should not be used indiscriminately for fungal, viral or non-infected skin conditions. > **Important:** Use only on the areas and for the duration recommended by a healthcare professional or the product label. --- ## Key Benefits * Helps prevent infection in **minor cuts, scrapes and superficial wounds**. * Provides antibacterial activity from three topical antibiotics. * Covers a range of susceptible **Gram-positive and Gram-negative bacteria**. * May help reduce the risk of bacterial infection in minor skin injuries. * Convenient topical application directly to the affected skin. * May be useful when multiple susceptible organisms are a concern. --- ## Uses / Indications ### 1. Minor Cuts and Scrapes May be used to help prevent bacterial infection in minor: * Cuts * Scratches * Abrasions * Superficial skin injuries ### 2. Minor Burns It may be used for selected **minor superficial burns** when recommended by a healthcare professional or product labeling. ### 3.

Deep wounds, puncture wounds, animal bites, extensive burns or spreading infections require medical evaluation. --- ## How It Works This medicine contains three antibiotics that work through different mechanisms. ### Bacitracin Bacitracin interferes with **bacterial cell-wall synthesis**, preventing susceptible bacteria from maintaining their protective cell wall. ### Neomycin Neomycin is an **aminoglycoside antibiotic** that binds to bacterial ribosomes and interferes with protein synthesis, leading to bacterial cell damage. ### Polymyxin B Polymyxin B interacts with bacterial cell membranes, particularly those of susceptible **Gram-negative bacteria**, disrupting membrane integrity. ### Simple Mechanism **Bacitracin → inhibits bacterial cell-wall formation** **Neomycin → interferes with bacterial protein production** **Polymyxin B → disrupts bacterial cell membranes** **Together → provide broad topical antibacterial activity against susceptible organisms.** --- ## Dosage & Administration > **Follow the specific product label or your healthcare professional's instructions.** ### General Application For minor skin injuries: 1. Clean the affected area gently with water and mild soap if appropriate. 2. Pat the area dry. 3. Apply a **small/thin amount** of the ointment to the affected area. 4. A sterile bandage may be used if recommended. 5. Wash your hands before and after application. Topical antibiotic ointments are generally applied **one to three times daily**, depending on the particular product and clinical situation. ### Important * Do not apply more than recommended. * Avoid prolonged continuous use unless directed by a healthcare professional. * Do not use on large areas of the body unless specifically prescribed. * Do not apply inside the eyes unless the product is specifically formulated and prescribed for ophthalmic use. ### Missed Application Apply when remembered unless it is nearly time for the next application. **Do not apply an excessive amount to compensate for a missed application.** --- ## Side Effects ### Common Side Effects Possible local reactions include: * Redness * Mild irritation * Burning * Stinging * Itching * Dryness ### Allergic Skin Reactions **Neomycin and bacitracin can cause allergic contact dermatitis** in some people, especially with repeated or prolonged use.

If accidental contact occurs, rinse thoroughly with clean water. ### Large or Deep Wounds Do not self-treat: * Deep wounds * Puncture wounds * Animal bites * Serious burns * Extensive skin injuries These may require professional treatment. ### Large Areas of Broken Skin Using topical antibiotics over extensive damaged skin can increase absorption and the risk of adverse effects. ### Allergy to Antibiotics Do not use if you have previously experienced an allergic reaction to: * Bacitracin * Neomycin * Polymyxin B * Related antibiotics Tell your healthcare professional about previous medication allergies. ### Prolonged Use Prolonged or unnecessary use can increase the risk of: * Skin sensitization * Irritation * Overgrowth of non-susceptible organisms * Antimicrobial resistance ### Worsening Infection Seek medical advice if redness, swelling, warmth, pain or drainage increases, or if fever develops. ### Children Use in children according to the product label or healthcare professional's advice.
