Amoxicillin can be mixed with gentamicin. If the patient has a serious infection, amoxicillin and gentamicin can be used together in a mixture, which can enhance the ability to fight infection, but if the patient’s infection is mild, it is not recommended that the patient use two anti-infective drugs at the same time. Amoxicillin is a broad-spectrum antibiotic suitable for respiratory tract infections, digestive tract infections, tonsillitis and other diseases. Gentamicin is suitable for the treatment of gram-negative bacillus infections, such as: peritonitis, biliary tract infections, reproductive system infections and other diseases. It is better for patients to choose the right drug according to their own situation. If the patient’s symptoms do not improve after using two antibiotics, or other symptoms appear, it may be that the patient is intolerant to these two drugs, and must stop using the drugs immediately, consult the doctor and change to other suitable drugs. Both antibiotics must be used appropriately under the guidance of a doctor, and should not be used without authorization to avoid adverse consequences.
