Bacitracin is a medication used for preventing minor skin infections from burns, scrapes or cuts, notes MedicineNet. Bacitracin works by killing or inhibiting the growth of susceptible bacteria, says Drugs.com.
Bacitracin only prevents bacterial infections and does not work for fungal or viral infections, reports MedicineNet. Patients should not use this medication over large areas of the body or on severe skin infections and should seek guidance from their doctors.
Patients who are allergic to petroleum jelly and mineral oil should not use bacitracin, warns Everyday Health. Although bacitracin is not believed to cause harm to an unborn baby, it is not clear whether this medication can harm a nursing baby or can pass into breast milk, as of 2015.
