Usually we talk about colds as acute upper respiratory tract infections, Amoxicillin can treat a wide range of colds caused by bacteria, but is not effective against viral colds. Most colds are caused by viruses, such as rhinoviruses, adenoviruses, influenza viruses, and some are also caused by enteroviruses. Colds caused by viruses are usually treated symptomatically and do not require antibacterial medication. A few colds are caused by bacteria, such as oral colonization bacteria hemolytic streptococcus, haemophilus influenzae and so on. Amoxicillin has a strong killing effect on bacteria and can be used to treat this type of cold, but it has no killing or inhibiting effect on viruses and cannot be used to treat viral colds. Amoxicillin needs to be used under the guidance of a doctor, not self-medication, during the use of medication, pay attention to a light diet, avoid greasy stimulating food, drink more water, pay attention to warmth and rest.
