Neomycin/Bacitracin
Overview
Neomycin/Bacitracin is a combination topical antibiotic ointment used to prevent and treat minor skin infections caused by small cuts, scrapes, or burns.
Mechanism of Action
Neomycin is an aminoglycoside antibiotic that inhibits bacterial protein synthesis, while bacitracin interferes with bacterial cell wall synthesis. Together, they provide broad-spectrum antibacterial coverage against many common skin pathogens.
Dosage and Administration
Clean the affected area and apply a small amount of the ointment 1 to 3 times daily. The treated area may be covered with a sterile bandage if necessary.
Side Effects
Prolonged use can occasionally lead to contact dermatitis or allergic sensitization, particularly due to the neomycin component. It may also promote the overgrowth of non-susceptible organisms, including fungi.
Contraindications
Contraindicated in patients with a history of hypersensitivity to any of its components. It should not be applied over large areas of the body or used for extended periods due to the risk of systemic absorption and potential nephrotoxicity or ototoxicity.
