Introduction
Ibuprofen sustained-release capsules can help reduce fever, especially for fevers caused by the common cold or influenza. However, it is important to pay attention to the appropriate population and dosage when using them. In daily life, when experiencing a fever, in addition to taking medication, it is important to drink plenty of water to promote metabolism, maintain good indoor ventilation, and avoid excessive warming. If other significant discomforts are present, adjust care methods according to specific symptoms.
Generally, ibuprofen sustained-release capsules can help reduce fever, especially for fevers caused by common colds or influenza. However, attention should be paid to the appropriate population and dosage when using them. A detailed explanation is as follows:
Ibuprofen sustained-release capsules belong to non-steroidal anti-inflammatory drugs (NSAIDs). They work by inhibiting prostaglandin synthesis, thereby reducing the release of pyrogenic substances in the body and helping to lower body temperature. When body temperature exceeds 38.5°C, the medication typically starts to take effect within 1–2 hours after administration, and its fever-reducing effect can last for approximately 12 hours, effectively alleviating discomfort caused by fever. However, this medication only targets the symptom of fever and cannot treat the underlying cause of the fever. If the fever is caused by bacterial infection or similar conditions, treatment should also target the underlying cause. When using ibuprofen sustained-release capsules, strictly follow the instructions on the label or recommended dosages to avoid overdose or frequent administration, which may increase the risk of gastrointestinal irritation.
In daily life, in addition to taking medication, individuals with fever should drink plenty of water to promote metabolism, maintain good indoor ventilation, and avoid excessive bundling. If other significant discomforts are present, adjust care methods according to specific symptoms to aid the body's recovery.
