Emphasis on the use of anti-drugs, especially anti-bacterial, which later form resistance. I have seen cases when someone is resistant to more than 8 classes of antibacterial drugs, among several causes of resistance, self-medication with the wrong class of drugs can be a major problem and reason why the drugs don't work.
Even if it is not an antibiotic or an antibacterial drug. Even anti-inflammatory or treatment medications, if used for a long time or abused without a doctor’s prescription, can lead to drug resistance and make future treatment more difficult.
Medicines are not something that can be used daily or for a long period, regardless of the type. Because fundamentally, most medicines are produced or refined through laboratory, industrial, and chemical processes. They are never good for our bodies, which is why we are only prescribed to use them when we are ill.
By the way, this also applies to dietary supplements. It is also not something good for our bodies if it is abused, as manufacturers advertise.
