Colds usually do not need to be treated with fluids, but may be treated with fluids if symptoms are severe. Whether or not you need to take medication depends on the type of medication; the same type of medication is not needed, and different medications can be used in combination. Colds are usually caused by rhinoviruses, adenoviruses, coronaviruses, etc. They are self-limiting and most of them can be cured on their own. General treatment, such as drinking plenty of water, resting and taking care of balanced nutrition, is the first option. If the symptoms are more serious, medication can be given. If there is a high fever or complications, consider infusion treatment, infusion and oral do not need to use the same drug at the same time, such as cephalosporin injection and cephalosporin oral drugs do not have to be repeated. However, cephalosporin injection and levofloxacin tablets can be used at the same time to strengthen the anti-infection. Cephalosporin can also be used together with oral phlegm remedies such as Ambroxol tablets. If the symptoms of cold and flu are serious, it is recommended to consult a doctor in a timely manner and standardize the treatment under the guidance of the doctor, so as not to delay the condition.
