Introduction
If body temperature exceeds 38.5℃, antipyretic medication is required for treatment. The effect usually becomes apparent within 20 to 30 minutes after taking the medication, leading to a decrease in body temperature. However, body temperature should be measured again half an hour to one hour after the fever has subsided, primarily to assess the treatment's effectiveness.
Under normal circumstances, body temperature should be measured half an hour to one hour after taking fever-reducing medication. The detailed explanation is as follows:
Fever is a common clinical symptom that may result from various factors. If body temperature exceeds 38.5°C, antipyretic medications such as ibuprofen sustained-release capsules or acetaminophen tablets should be used, as they have fever-reducing and pain-relieving effects. These medications typically begin to take effect noticeably within 20 to 30 minutes after administration, leading to a decrease in body temperature. However, it is recommended to wait half an hour to one hour after taking the medication before measuring body temperature again, primarily to assess the treatment's effectiveness.
If high fever persists despite taking antipyretic drugs, patients should seek medical attention at a正规 hospital as soon as possible. Diagnostic tests such as complete blood count (CBC) and C-reactive protein (CRP) can help confirm the underlying cause. Once the diagnosis is established, treatment should focus on addressing the primary disease. During treatment, patients should maintain a light diet, drink plenty of warm water, stay warm, and promote metabolism, which helps reduce fever and supports recovery.
