After taking ibuprofen once and the fever has subsided, should I continue taking it?

Fever reduction generally refers to antipyresis. After taking ibuprofen once and the fever subsides, if fever recurs, the medication should be taken again. If there is no recurrence of fever, further dosage is unnecessary. Specific analysis is as follows:

1. Further medication required

Ibuprofen belongs to the class of analgesic and antipyretic drugs. It inhibits cyclooxygenase, reduces prostaglandin synthesis, and achieves fever-reducing effects through the hypothalamic temperature regulation center. If body temperature rises again after taking the medication and exceeds 38.5°C, ibuprofen should be taken again for fever reduction. However, attention must be paid to the dosing interval—generally, the drug can be administered again after 4–6 hours.

2. No further medication required

After taking ibuprofen, if body temperature does not rise again or remains below 38.5°C, there is no need to take additional doses. Taking the medication unnecessarily may cause body temperature to drop below the normal range, which provides no health benefit.

Patients should not self-medicate but instead use medication under the guidance of a qualified physician based on their specific condition. During treatment, instructions from healthcare professionals must be strictly followed.
