Many doctors now restrict prescriptions for some antibiotics. They keep the most effective antibiotics in reserve for the most serious outbreaks of treatable diseases.
What is the main reason for this?
1 )
Antibiotics are not as effective as other medicines.
2 )
Antibiotics are only effective against diseases caused by bacteria.
Resistant strains of bacteria may develop.
4 )
Taking antibiotics may weaken the immune system.
