Oseltamivir is an antiviral drug and can be used to treat influenza A. In case of viral combined with bacterial infections, oseltamivir and antibacterial drugs, which work by killing bacteria, can be taken at the same time. Bacteria and viruses are different pathogenic microorganisms that can cause disease alone or in combination. In addition, there are indications for the use of medications, and they should be used only when there is clear evidence of infection on blood or imaging. Misuse of medications at any time can be detrimental to the body and may lead to drug resistance. Anti-inflammatory drugs are clinically known as non-steroidal anti-inflammatory drugs or anti-inflammatory drugs such as glucocorticoids, not antibacterial drugs as commonly understood.
