Colds are mainly caused by the infection of our upper respiratory tract by various pathogens, including viruses, bacteria, mycoplasma, etc. Rhinitis is usually related to infections, and a cold can trigger rhinitis. However, other factors, such as allergies or temperature changes, can also produce symptoms similar to a cold. Therefore, cold medicines often contain medications for treating rhinitis, so some patients experiencing rhinitis may find cold medicines to be effective. However, besides containing rhinitis medications, cold medicines also include fever reducers and vasoconstrictive cough suppressants. Thus, to treat rhinitis, it is still better to use proper rhinitis medications instead of substituting them with cold medicines. (Please use medication under the guidance of a doctor to avoid self-medication.)
