As everyone knows that antibiotics are medicines to use for disinfecting but it is not exactly the truth about it. Because many people always use antibiotics in the way they think but antibiotics is not easy to use. That’s why there are many reasons for using antibiotics.
There are many reasons of the misunderstanding. First, antibiotics are medicines that fight and kill infections caused by bacteria. Second, our body has an immune system which means that our body can be treated by itself. The last reason is many people thought that antibiotics do not have any side effect. For example, many people always take antibiotics when they feel sick, have the flu or have a runny nose and they thought that to take antibiotics is treatment but these illnesses aren’t caused by bacteria but by viruses, and when they take antibiotics, they don’t follow the prescription. Because of many misunderstanding about using antibiotics, bacteria will change and become to resist the effect of antibiotics that call 'antibiotic resistance'. We can prevent this problem such as to consult doctor or pharmacist when you feel sick or necessary to take antibiotics, improve hygiene such as wash a hand and wearing mark when you are infected to limit spread of infection, and use viruses to kill bacteria.
To conclusion, Because using antibiotics is wrong to cause antibiotics resistance and will lead to the bad effect such as allergic and a longer-largting illness
