COVID-19 (coronavirus): restrictions are in place nationwide. Get advice to stop the spread 

Antibiotics are medicines used to treat some bacterial infections. They work by killing bacteria or stopping them from growing.

You may need antibiotics if you have an infection that is unlikely to go away without them. In this case, your doctor may prescribe a course of antibiotics for you.

Antibiotics do not work for viral infections such as colds and flu, and most coughs and sore throats.

Antibiotic resistance is a big problem. Taking antibiotics when you do not need them can mean they will not work for you in the future.
