Question:
My child is 47 months old and weighs 14.3 kg (about 31.5 lbs). I need help figuring out the correct dosage for fever reducers. What is the right amount to give?
Answer:
Hello. Here is a guide for fever reducer dosages for a 47-month-old (almost 4 years old) child weighing 14.3 kg.
First, please check the label on the bottle of fever reducer (syrup/suspension) you have at home.
You will need the following information:
1. Medication Name (e.g., Tylenol, Motrin, Advil, etc.)
2. Concentration (Strength) — This is indicated on the bottle as "XX mg/mL" or "XX mg/5 mL".
→ If you provide these two details, I can calculate the exact dosage in mL for you.

### 📌 General Dosage Ranges (Use after checking your bottle's label)
#### Acetaminophen (e.g., Tylenol)
* Dose: 143–215 mg (based on 10–15 mg/kg)
* Frequency: Every 4 to 6 hours, up to 5 times a day.
* Based on Children's Tylenol suspension (160 mg/5 mL): approx. 4.5–6.7 mL
#### Ibuprofen (e.g., Advil, Motrin)
* Dose: 71–143 mg (based on 5-10 mg/kg)
* Frequency: Every 6 to 8 hours, up to 4 times a day.
* Based on Children's Ibuprofen suspension (100 mg/5 mL): approx. 3.6–7.2 mL
#### Dexibuprofen
* Dose: 71–100 mg (based on 5–7 mg/kg)
* Frequency: Every 6 to 8 hours, up to 4 times a day.
* Based on a common suspension strength (12 mg/mL): approx. 6–8.3 mL

### ⚠️ Safety Precautions
* Always use the dosing cup or syringe that comes with the medication. Do not use kitchen spoons.
* Giving two different types of fever reducers at the same time is generally not recommended.
* Give medicine based on your child's discomfort, not just the number on the thermometer.
If you can provide the medication name and its concentration, I can give you a more precise dosage recommendation.
