Colds and flu are caused by viruses. Antibiotics treat bacterial infections, so they won’t treat the virus causing a cold or flu.
Your GP can assess whether you need treatment and advise on symptom relief. Sometimes a bacterial infection occurs as well, which needs a separate assessment.
If you’re getting worse or are worried about your symptoms, seek medical advice.
Infection Prevention and Control Week runs from 18–24 October.
