Question:

My 9-year-old son, who weighs 41 kg, currently has a mild fever. It might be due to fatigue or the early stages of a cold. I want to be prepared to give him a fever reducer if his temperature goes up. He rarely gets sick, so I am not sure about the correct dosage. We have Dexibuprofen (Maxibuprofen) syrup at home. How much should I give him?

Answer:

It is completely understandable to be concerned about your child's early cold symptoms. Knowing his exact weight is very helpful for calculating the correct dosage.

Dexibuprofen Dosage Calculation

First, please check the bottle's label to confirm the concentration of the medication. Most standard syrups will say something like "12 mg/mL."

For standard Dexibuprofen syrup (based on a 12 mg/mL concentration):

• For a 41 kg child, the single dose is between 205–287 mg.

• This translates to 17–24 mL per dose.

• You can administer this amount every 6–8 hours as needed.

• Do not exceed 4 doses in a 24-hour period.

⚠️ Important Precautions

• Always prioritize the specific instructions printed on the product label.

• Be sure to measure the medication using the enclosed measuring cup or oral syringe. Never use a regular kitchen spoon, as it will not provide an accurate measurement.

Current Care Recommendations

• You only need to give the fever reducer if the fever is making your child actively uncomfortable or irritable. If he is playing and resting comfortably, you can simply monitor him.

• Dress him in light, breathable clothing and keep the room at a comfortable temperature.

• Encourage him to drink plenty of fluids, such as water or electrolyte beverages, to prevent dehydration.

• Avoid physical cooling methods like tepid water sponging or ice packs, as these can cause shivering and discomfort.

When to See a Doctor

Please seek in-person medical evaluation if you notice any of the following red flag symptoms:

• He is struggling to breathe or his lips are turning blue.

• He has not urinated for 8 hours or more.

• He becomes severely lethargic, unresponsive, or difficult to wake up.

• The fever persists for more than 3 days or continues to worsen.

If you are ever unsure about his symptoms or if his condition changes, please consult your pediatrician promptly for a thorough physical examination.
