Question:

My child took an ibuprofen-type fever reducer (Maxibufen). The fever is now low-grade, but they still have a severe headache and body aches. In this case, is it okay to give them an acetaminophen-based medicine as well?

Answer:

It must be worrying that the symptoms persist.

Cross-dosing is possible, but it should be approached with caution.

【Summary of the Current Situation】

After taking an ibuprofen-type medication (dexibuprofen), the fever has subsided, but headache and body aches remain.

【Principles of Cross-Dosing】

• You must wait at least 2-3 hours after an ibuprofen-type medication before giving acetaminophen.

• The standard dosing interval for each medication must be strictly followed.

→ Ibuprofen-type medications: Every 6-8 hours

→ Acetaminophen: Every 4-6 hours

• Do not exceed the maximum daily doses for each medication.

→ Ibuprofen-type medications: 4 times a day

→ Acetaminophen: 5 times a day

【Safer Alternatives】

1. Try Non-Pharmacological Methods First

• Ensure adequate hydration.

• Rest in a dark, quiet room (to help with the headache).

• Dress in light clothing and maintain a comfortable room temperature.

2. Re-evaluate with a Single Medication

• If it has been 6-8 hours since the last dose of the ibuprofen-type medication → Consider giving another dose of the same medication.

• If the interval has not yet passed → Continue with non-pharmacological methods and observe for another 1-2 hours before reassessing.

3. Use Cross-Dosing as a Last Resort

• Only when symptoms are not controlled by a single medication and the child is very uncomfortable.

• Carefully record the time and dosage of each medication to avoid confusion.

【When to Seek Medical Attention the Same Day】

• The headache worsens or is accompanied by a stiff neck.

• Accompanied by repeated vomiting.

• The child seems drowsy, confused, or less alert.

• The fever returns or persists for more than 3 days.

For now, try the non-pharmacological methods first and let us know how the symptoms change.
