• Finishing all antibiotic medications prescribed, even if symptoms stop. This includes not missing or skipping doses. Blood levels of the antibiotic must stay within a high enough range to kill bacteria.

  • Avoiding some "antibacterial" soaps and cleansers. Choose products with bleach, alcohol, ammonia or hydrogen peroxide, which kill bacteria without promoting resistance.

  • Immunization. Many bacterial infections can be prevented through immunization. Patients should discuss the options with their physicians. Specifically, patients with chronic conditions and those over the age of 60 should receive the pneumococcal vaccine.
