Question:

Hello Doctor, my 4-month-old baby currently weighs 9 kg. I would like to know the correct dosage of Champ Red (Acetaminophen) syrup for my baby. How many milliliters (ml) should I administer?

Answer:

Here is the dosage guide for Champ Red (Acetaminophen) for a 4-month-old baby weighing 9 kg.

[Dosage Calculation]

• Based on body weight: 90–135 mg (9 kg × 10–15 mg/kg)

• Based on Champ Red syrup (32 mg/ml): 2.8–4.2 ml

• Recommended dosage: 3.5 ml (112 mg)

• Dosing interval: Every 4–6 hours, up to a maximum of 5 times a day

[How to Administer]

• Accurate measurement: Use the syringe enclosed with the medicine bottle.

• Administer slowly into the inside of the baby's cheek.

• If the baby vomits, you can re-administer the medication after 30 minutes.

⚠️ Precautions:

- Even if there is a fever, if your baby is playing and eating well, there is no strict need to give a fever reducer.

- Only administer the medication if the body temperature is 38.5°C or higher AND the baby is fussy or uncomfortable.

- If the fever persists for more than 3 days, please visit a pediatrician for a consultation.

Please double-check that the medicine bottle clearly indicates "32 mg/ml." If your medication has a different concentration, please ask again!
