Answer

  • Antibiotics are a group of medicines used to kill disease-causing bacteria and certain protozoa.
  • The doctor selects and prescribes the antibiotic best suited for our disease.
  • If taken in extra dose, they can kill the useful bacteria present in our body.
  • If the course of antibiotics is not completed, the bacteria develop resistance to that antibiotic making it ineffective.
  • Therefore, antibiotics should be taken only when prescribed by a doctor.
