The fever and cough can be reduced in a few days depending on a number of factors and cannot be generalized. If the fever and cough are caused by the common cold, the fever can usually be reduced in 2-3 days with active medication, such as ibuprofen suspension, busulfan oral anti-inflammatory solution, and also intra-anal filling of fever suppositories, which may take 3-5 days to reduce the fever in some children. In the case of herpes pharyngitis and pharyngeal conjunctivitis, both diseases have a longer fever duration, which can last up to a week or even longer. In addition, if the fever and cough are followed by a bacterial infection, such as rhinitis followed by bronchitis or even pneumonia, the fever may be prolonged. In addition, people who have frequent colds and fevers can get flu shots or pneumococcal vaccines, which have a good effect on reducing cold symptoms.
