Antibiotic use for minor illnesses like common colds or viral fevers are a dangerous practice. It contributes to development of drug resistance, but some doctors prescribe them because they get benefits. Our teachers in med school warned us about prescribing antibiotics for minor ailments. Also, another practice that's causing drug resistance to build is people buying meds directly from pharmacies without consulting a doctor. It's a normal thing in my town and that worries me.
