Taking those common antibiotics for viral colds, such as cephalosporins or amoxicillin, has little therapeutic effect. Viral colds must take antiviral drugs in order to have a better therapeutic effect. Commonly used antivirals include oseltamivir and ribavirin, etc., which can be taken orally. However, it should be noted that influenza virus and parainfluenza virus, including influenza A and B, can be treated with oseltamivir, while other viral infections are not effective with oseltamivir and can be treated with ribavirin as an adjunct. Viral infections usually use antiviral drugs only to play an auxiliary role, antiviral drugs can not directly kill the virus completely, viral infections still depend on the person’s own resistance to healing. Therefore, in addition to taking antiviral drugs during a viral cold, one must rest more, drink more water, and maintain good physical strength and body condition, which can help the cold heal.
