- [0](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/0/) — Germs come in different kinds, and the two you hear about most are bacteria and viruses: bacteria are tiny living cells, while viruses are far smaller and can only multiply inside our own cells.
- [1](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/1/) — Antibiotics are medicines that kill bacteria or stop them growing, but they cannot touch a virus, so they do nothing for a cold, flu or most sore throats.
- [2](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/2/) — Picture a key that only fits one lock: an antibiotic fits the machinery of bacteria, and a virus simply has no such lock.
- [3](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/3/) — Every time antibiotics are used, the few bacteria that happen to survive can multiply, so careless use breeds germs the medicine no longer kills; this is called antibiotic resistance.
- [4](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/4/) — All medicines can have side effects, unwanted effects on top of the ones you want, which is why doctors weigh the good against the bad before they prescribe.
- [5](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/5/) — Antibiotics kill bacteria or stop them multiplying, and they have no effect on viruses.
- [6](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/6/) — Colds, flu and most coughs and sore throats are caused by viruses, so antibiotics do not help them get better faster.
- [7](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/7/) — A chest infection caused by bacteria can improve within a couple of days on antibiotics, but doctors ask patients to take the course exactly as prescribed and to check with them before stopping.
- [8](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/8/) — Antibiotic resistance means the bacteria change so the medicine stops working; it is the bacteria that become resistant, not the person's body.
- [9](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/9/) — Using leftover antibiotics is unsafe, because they may be the wrong medicine or dose for a new illness and they help resistance spread.
- [10](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/10/) — Antibiotics also kill some of the helpful bacteria in the gut, so a runny tummy is a common side effect and usually not an allergy.
- [11](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/11/) — The leaflet in a medicine box lists every side effect ever reported, and most people get none or only mild ones.
- [12](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/12/) — Some older hay fever tablets (antihistamines) reach the brain and cause sleepiness, and pharmacists can suggest non-drowsy kinds.
- [13](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/13/) — An itchy rash after a new medicine can be an allergic reaction, so the doctor changes the medicine and writes the reaction in the patient's record.
- [14](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/14/) — Some medicines interact, making each other stronger or weaker, so doctors and pharmacists need to know about every medicine and herbal remedy a person takes.
- [15](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/15/) — Alexander Fleming noticed in 1928 that a mould killed bacteria on a dish, and Howard Florey, Ernst Chain and their team turned penicillin into a medicine in the 1940s; eating mouldy food is not a medicine and can make you ill.
- [16](https://md.mova.elamur.ai/free/en/corpora/school/medicine/19-antibiotics-viruses-and-side-effects/16/) — Antibiotics have saved millions of lives from infections that once often killed, such as infected wounds and pneumonia, an infection of the lungs.
