Drugs that kill infected bacteria inside the human body without harming body cells
Antibiotics mean that most bacterial diseases are treatable
Antibioticresistance
Certain antibiotics are no longer effective against certain bacteria because antibiotics have been overused, causing the bacteria to evolve and become resistant
Antibiotic resistance is a serious problem, as it may make bacterial diseases very difficult to treat in the future
Doctors are careful when prescribing antibiotics, using specific antibiotics to treat specific bacteria
Antibiotics cannot kill viruses, so doctors will not prescribe them for conditions caused by viruses
Painkillers
Drugs that treat the symptoms of a disease by relieving pain, but do not kill pathogens or treat the disease itself
Viruses live and reproduce inside human cells, making it difficult to develop drugs that kill viruses without also damaging the body's tissues
