Misuse of antibiotics refers to the use of antibiotics when they should not be used, i.e., overdosing, not using them symptomatically, or not using them in strict accordance with the regulations. Patients should stop using antibiotics immediately and go to the hospital to check their health to avoid adverse consequences. As patients lack basic understanding of drugs and do not know the specific indications, they may buy antibiotics in pharmacies or online, and have the misconception that “the more expensive the drug, the better, the higher grade the better”, leading to antibiotic abuse. A small number of pharmacies are not well managed and do not strictly check doctors’ prescriptions, which also creates conditions for patients to abuse antibiotics. If patients overuse antibiotics, it is easy to cause some toxic side effects, and then damage the human system, such as nerves, liver and kidney function, more serious damage to patients with abnormal liver and kidney function. The non-appropriate use of antibiotics may cause allergic reactions in some people, such as anaphylaxis, and even death in serious cases, and may lead to drug resistance, the body is not sensitive to antibiotics, once the occurrence of drug-resistant bacteria infection, can lead to ineffective antibiotic treatment, unable to control the infection.
