Neomycin and polymyxin B sulfates are common antibiotic medications, often found in topical ointments. They are used to prevent or treat minor skin infections.
What They Are and What They Treat
Neomycin and polymyxin B are distinct antibiotics frequently combined to broaden their effectiveness against various bacteria. This combination is commonly found in topical ointments for external skin use. These antibiotics work to slow or stop bacterial growth. They are typically used for superficial skin issues such as minor cuts, scrapes, and burns to prevent infection.
How to Apply the Medication
Wash your hands thoroughly with soap and water before application. Gently clean the affected skin area with mild soap and water, then pat it dry. Apply a small amount of the ointment, creating a thin layer directly over the wound. The ointment is typically applied one to three times daily, or as directed by a healthcare professional. If a dose is missed, apply it as soon as remembered; however, if it is almost time for the next scheduled dose, skip the missed one and continue with the regular dosing schedule.
Safety Considerations and When to Seek Help
While generally well-tolerated, some individuals may experience mild side effects such as burning, redness, or irritation at the application site. If these effects persist or worsen, consult a healthcare provider. This medication should not be used on deep or puncture wounds, animal bites, or serious burns. Avoid contact with the eyes or mouth; if accidental contact occurs, rinse the area thoroughly with water. Signs of a more serious allergic reaction include a rash, hives, itching, or swelling of the face, lips, tongue, or throat. Difficulty breathing or severe dizziness also warrant immediate medical attention. Watch for signs indicating the infection is not improving or is worsening, such as increased pain, spreading redness, swelling, or the presence of pus. If symptoms do not improve within a few days or worsen, seek advice from a healthcare professional. Prolonged use of the medication without medical supervision is generally not recommended as it can lead to the overgrowth of non-susceptible organisms or contribute to antibiotic resistance.
Storing and Disposing of the Medication
Store neomycin and polymyxin B sulfates ointment in a closed container at room temperature. Keep it away from excessive heat, moisture, and direct light. Ensure the medication is kept out of reach of children and pets. Dispose of expired or unneeded medication properly. Do not flush it down the toilet or pour it down a drain; instead, consult local guidelines for medication disposal programs.
