Although some sources assert that there remains a lack of knowledge on which antibiotic use generates the most risk to humans, [47] policies and regulations have been placed to limit any harmful effects, such as the potential of bacteria developing antibiotic resistance within livestock, and that bacteria transferring resistance genes to human ...
The side effects of penicillin are bodily responses to penicillin and closely related antibiotics that do not relate directly to its effect on bacteria. A side effect is an effect that is not intended with normal dosing. [1] Some of these reactions are visible and some occur in the body's organs or blood.

[106] Many antibiotics are frequently prescribed to treat symptoms or diseases that do not respond to antibiotics or that are likely to resolve without treatment. Also, incorrect or suboptimal antibiotics are prescribed for certain bacterial infections.
Overuse of antibiotics and other antimicrobial drugs during the coronavirus pandemic is helping bacteria develop resistance that will render these important medicines ineffective over time, the ...

[12] Antibiotics are often overused due to physicians’ overprescription or unreasonable medical requests made by patients. Unlike other prescription drugs, antibiotics are not addictive.

A 2004 study showed that people in the United States with S. aureus infection had, on average, three times the length of hospital stay (14.3 vs. 4.5 days), incurred three times the total cost ($48,824 vs. $14,141), and experienced five times the risk of in-hospital death (11.2% vs 2.3%) than people without this infection.

The symptoms of disease appear as pathogenic bacteria damage host tissues or interfere with their function. The bacteria can damage host cells directly or indirectly by provoking an immune response that inadvertently damages host cells, [ 21 ] or by releasing toxins .
