Introduction
In general, fever associated with acute pharyngitis may last about one week. In some patients with more severe conditions, the duration may be slightly longer. The exact duration varies depending on the severity of the illness and the patient's physical condition. During the early stage of the disease, low-grade fever may occur and could last approximately one week. It is recommended to observe first and avoid using medication prematurely.
In general, fever associated with acute pharyngitis may last about one week. In more severe cases, the duration may be slightly longer. The exact duration varies depending on the severity of the illness and the patient's overall health condition. Detailed analysis is as follows:
During the early stage of acute pharyngitis, patients may experience low-grade fever, which could last approximately one week. It is recommended to observe first without rushing to use medication, as the fever usually gradually subsides and resolves within 3 to 7 days. If the condition progresses further, most patients will develop high fever. If the fever persists beyond 3 to 5 days without improvement and throat pain continues to worsen, it is typically caused by a significant bacterial infection. For patients without a history of antibiotic allergy, penicillin-class antibiotics are generally the first-line treatment under medical guidance, such as amoxicillin capsules or penicillin V potassium tablets. If a viral infection is also present, antiviral medications like acyclovir tablets or oseltamivir phosphate capsules may be used. After starting appropriate medication, fever symptoms generally begin to diminish gradually.
It should be noted that in some patients, fever may last longer than one week, which is often closely related to the severity of local infection. It is advisable to seek timely medical attention and receive appropriate treatment under a doctor’s supervision.
