Antibiotics are only effective against bacteria. Because some sore throats are caused by a virus, antibiotics would not work. Most health authorities advise against the over-use of antibiotics so that resistance doesn’t become a big problem.6
For the same reasons, other viral infections like flu should not be treated with antibiotics either6
If a sore throat persists or is particularly severe, you should see your doctor.
Antibiotics may be prescribed by your doctor in situations of bacteria related infections*.
