Whether you can take amoxicillin for cold or not mainly depends on whether it is combined with bacterial infection. In clinical practice, cold is usually caused by virus, and antiviral drugs are given as early as possible within 48 hours to effectively relieve the symptoms of fever, runny nose, sneezing, sore throat, itchy throat and cough caused by cold. If there are still cold symptoms after 48 hours, and the blood count indicates elevated total white blood cells and neutrophils, it means that the virus has combined with bacterial infection, and anti-infective drugs need to be given as soon as possible. Amoxicillin is a kind of antibiotic, which has good clinical effect on respiratory tract infection, so if the cold is combined with bacterial infection, you can consider adding amoxicillin capsule to fight infection. But if the blood routine is not high, suggesting no bacterial infection, generally still give antiviral drugs and Chinese herbal medicine treatment, do not just abuse antibiotics, including amoxicillin capsules. So taking amoxicillin capsules for cold must be a virus combined with bacterial infection, which is suggested by both clinical manifestations and auxiliary examinations.
