1. What are antibiotics?
Antibiotics are medicines used to treat infections caused by bacteria. They work by killing bacteria or stopping them from multiplying. Antibiotics are not effective against viruses, such as those that cause colds or flu.
2. Do antibiotics work for colds and flu?
No. Colds, flu, and most sore throats are caused by viruses, not bacteria. Antibiotics will not shorten the illness or improve recovery from viral infections and may cause unnecessary side effects.
3. Why won’t my GP prescribe antibiotics for every infection?
Your GP assesses whether an infection is likely to be bacterial before prescribing antibiotics. Using antibiotics when they are not needed increases the risk of side effects and contributes to antibiotic resistance, which is a serious public health issue.
4. What is antibiotic resistance?
Antibiotic resistance occurs when bacteria change over time and no longer respond to antibiotics. This means infections can become harder to treat and may require stronger medicines, hospital care, or longer recovery times.
5. Can I stop antibiotics once I feel better?
You should take antibiotics exactly as prescribed by your GP. Stopping treatment early may allow some bacteria to survive, increasing the risk of the infection returning or contributing to antibiotic resistance.
6. Are antibiotics safe?
Antibiotics are generally safe when used appropriately. Common side effects include nausea, diarrhoea, or mild stomach upset. More serious reactions are uncommon but can occur, so it is important to seek medical advice if you notice concerning symptoms.
7. Can I use leftover antibiotics or someone else’s prescription?
No. Antibiotics should only be taken if prescribed specifically for you and for your current illness. Using leftover or shared antibiotics may be unsafe and may not treat the infection effectively.
8. Do antibiotics interact with other medicines?
Some antibiotics can interact with other medications, including certain supplements or contraceptives. Always tell your GP or pharmacist about all medicines you are taking to ensure antibiotics are safe for you.
9. Do antibiotics affect gut health?
Antibiotics can affect the normal bacteria in your gut, sometimes causing diarrhoea or stomach discomfort. These effects are usually short-term and improve after finishing the course.
10. When should I seek medical advice while taking antibiotics?
You should contact your GP if your symptoms worsen, do not improve, or if you experience side effects such as a rash, severe diarrhoea, breathing difficulty, or swelling of the face or lips.
