The answer is all of the above.
- Medicine misuse means taking a medicine during a wrong dose or which is not prescribed.
- Here, taking medication which is not prescribed is of course medicine misuse.
- Taking medication which was prescribed for you in the past is also medicine misuse.
- The above two occurs quite frequently when people take antibiotics during cough and cold. It is really a wrong notion that antibiotics can cure you from cold. But antibiotics only work on bacteria. They cannot work on viruses because viruses don't have their own metabolic pathways. Common cold is a viral disease so it is advisable not to take antibiotics during this time unless advised by doctors. And many people take antibiotics even after the prescribed dose. Antibiotics can have fatal effect on good bacteria also which can lead to bad health. So it is always advised to take antibiotics when and only doctors prescribe you.
- Mixing medications with drugs is another medicine misuse example. Many people are addicted to drugs, etc. and they take drugs which are not prescribed.
Hope you could get an idea from here.
