Amoxicillin is usually not to be drunk for dry cough, which is one of the most common clinical symptoms and overwhelmingly indicates that there is no infection, and in particular, the absence of a bacterial infection is highly probable. Therefore, dry cough is most often seen in upper respiratory tract infections such as the common cold, pharyngitis, laryngitis, etc. Or other chronic inflammatory diseases of the airways, such as bronchial asthma, chronic bronchitis, etc. It is also seen in interstitial lung diseases. Amoxicillin belongs to the penicillin group of antibiotics, which has a wide range of antibacterial activity against a wide range of bacteria. However, it has no effect on viruses, and has no effect on other diseases of the respiratory tract caused by non-bacterial infections; on the contrary, abuse can cause drug resistance. Therefore, if amoxicillin is to be given for a dry cough, it should not be given unless there is clear evidence of infection, such as markedly elevated blood counts and typical bacterial pneumonia changes in the lungs. Other than that, amoxicillin is generally not allowed.
