There are no quick and cheap cold remedies. The common cold requires no special treatment, while influenza is treated with antiviral therapy.
Common colds are self-limiting and usually do not require special treatment, and can be cured within a week or so. Therefore, there is no specific medicine for colds, so just drink plenty of fluids and stay in bed.
However, if the influenza virus infection is the cause of influenza, you can take targeted antiviral treatment, using drugs such as oseltamivir. It can control the infection process and speed up the recovery of the cold. If the cough is severe, you can use codeine to stop coughing. If you have a lot of phlegm, you can use Ambroxol to reduce phlegm.
If the cold symptoms are serious, it is recommended to consult a doctor in time, under the guidance of the doctor for symptomatic treatment.
