Quick Answer
Use topical antibiotic ointments for minor cuts, scrapes, and burns that are not deep or large, while oral antibiotics are reserved for more severe infections, such as those that involve the bone, joint, or bloodstream. Consider wound depth, size, and symptoms when deciding between the two. A general rule of thumb is to use oral antibiotics for infections that are 1 cm or deeper.
Choosing Topical Antibiotic Ointments
When to use topical antibiotic ointments: minor cuts, scrapes, and burns that are not deep or large. Apply the ointment directly to the affected area, usually 2-3 times a day. For best results, apply the ointment after cleaning the wound with soap and water, and then cover the area with a bandage. Some common topical antibiotic ointments include Neosporin, Bacitracin, and Polysporin. When selecting a topical antibiotic ointment, consider the type of bacteria most likely to infect the wound and the ointment’s efficacy against that bacteria.
Selecting Oral Antibiotics
When to use oral antibiotics: more severe infections that involve the bone, joint, or bloodstream. Oral antibiotics are often prescribed for infections that are 1 cm or deeper, or if symptoms persist or worsen despite topical treatment. Before taking oral antibiotics, understand the potential side effects and interactions with other medications. Some common oral antibiotics include Amoxicillin, Cephalexin, and Ciprofloxacin. When selecting an oral antibiotic, consider the type of bacteria most likely to infect the wound and the antibiotic’s efficacy against that bacteria, as well as the risk of antibiotic resistance.
