Question:
My 16 kg child suddenly developed a high fever of 39°C (102.2°F) in the middle of the night, and in a panic, I gave them two pouches (12 mL) of dexibuprofen (Maxibufen) syrup. I heard that a single dose in milliliters shouldn't exceed half the child's weight, so I am worried I gave an overdose. Will my child be okay?
Answer:
It is completely understandable to feel overwhelmed and act quickly when your child suddenly spikes a high fever in the middle of the night.
Dosage Assessment
For a 16 kg child given 12 mL of standard dexibuprofen syrup (concentrated at 12 mg/mL), the total dose administered was approximately 144 mg.
Recommended single dose: 5–7 mg/kg = 80–112 mg (roughly 6.5–9 mL)
Dose administered: Approximately 9 mg/kg (144 mg)
While 12 mL is slightly above the typical recommended single dose, a single instance at this level is generally not considered toxic or dangerous.
What to Do Now
Monitor at home: If your child is drinking fluids, urinating normally, and behaving or resting comfortably, you can safely continue observing them at home.
When to seek emergency care: Take your child to an urgent care clinic or emergency room immediately if you observe any of the following warning signs:
Repeated vomiting or severe abdominal pain
No urination for more than 8 hours
Extreme lethargy, floppiness, or unusual difficulty waking up
Rapid breathing, grunting, or bluish lips
Guidelines for Subsequent Doses
Wait interval: Wait at least 6 to 8 hours before offering another dose of dexibuprofen.
Daily maximum limit: Ensure the total amount given over a 24-hour period does not exceed 28 mg/kg (approximately 448 mg or roughly 37 mL total). If the medication label specifies a stricter daily maximum (such as a maximum of 25 mL per day for children under 30 kg), follow the label's cap.
Adjust future doses: For any upcoming doses, reduce the amount to approximately 8 mL (about 96 mg), given no more than 3 to 4 times per day.
Tips for Safe Medication Administration
Always check the concentration (mg/mL) on the packaging before dosing.
Use the calibrated oral syringe or measuring cup provided with the medicine rather than standard kitchen spoons.
A standard dosing guide for dexibuprofen is: Weight (kg) × 5 to 7 mg = required mg per dose, which can then be converted to mL based on the medication's concentration.
For now, monitor your child's general condition and hydration closely. If no alarming symptoms appear, simply adjust down to the correct dosage for subsequent doses. If your child's fever persists for more than a few days, or if you notice any unusual symptoms, consult your pediatrician or local healthcare provider for an in-person evaluation.
