antibiotics

antibiotics are medicines used to kill bacteria that cause infections.

a doctor will choose an antibiotic to treat an illness based on:

  • whether taking an antibiotic will reduce the length or severity of the illness.
  • whether the person is allergic to any antibiotics.
  • how likely it is that a certain antibiotic will kill the bacteria believed to be causing the symptoms.
  • the symptoms and the severity of the illness.
  • other medical problems that the person has.
  • the person's age. (for example, some antibiotics are not safe for children.)
  • whether a woman is pregnant.
