Antibiotics, narcotics, and tranquilizers should be used with caution in the elderly and should be administered as prescribed by a physician. 1. Antibiotics: many elderly people have renal hypoplasia and reduced blood supply to the inner ear, while aminoglycoside antibiotics (such as gentamicin, kanamycin, etc.) have nephrotoxicity and ototoxicity, which will aggravate the renal function of the elderly and affect hearing. 2. Anesthesia drugs: the elderly are very sensitive to anesthesia drugs, so the relative safety range of anesthesia drugs is small, and it is easy to cause coma and respiratory depression and other serious conditions in the elderly, for drugs such as morphine and codeine, the elderly should be used with caution. 3. Stabilizers: Stabilizers are often used to stabilize the patient’s mood and improve sleep. Especially for the elderly, they are used more frequently, but Valium is not easy to be metabolized and can easily accumulate in the body, causing vomiting, insomnia and other side effects in the elderly, so they need to be used with caution. Elderly people need to follow the doctor’s instructions, and once an adverse reaction occurs, it is necessary to consult a doctor in a timely manner, do not take medication on their own.
