Question:

My 33-month-old child has a fever and symptoms of gastroenteritis. They vomited three times yesterday and completely emptied their stomach. They also had diarrhea once yesterday and once today. Their temperature was initially a mild 37.5°C but rose to 38.2°C right before bedtime. I gave a fever reducer immediately, but two hours have passed, and the fever is still going strong at 38.5°C. I am considering alternating fever reducers, but what should I do? We are currently traveling abroad, which makes me even more anxious. Please help.

Answer:

It must be very worrying to have your child fall sick while traveling abroad. It sounds like the fever is persisting along with symptoms of gastroenteritis.

Current Situation Assessment:

• 38.5°C fever + vomiting + diarrhea = typical acute gastroenteritis.

• Fever persists even 2 hours after taking a fever reducer.

• A 33-month-old child is at a high risk of dehydration during acute gastroenteritis.

What to do immediately:

1. Cross-dosing is possible → You can give Ibuprofen right now.

(This is safe since 2 hours have passed since taking Acetaminophen).

2. Preventing dehydration is the most important step:

• Give 1-2 sips of water or an electrolyte drink every 5-10 minutes.

• Do NOT give a large amount at once → give small amounts frequently.

3. Focus on observing the child's overall condition rather than just checking the temperature.

🚨 Go to a local hospital immediately if you notice:

• No urination for more than 8 hours.

• Crying without tears or severely dry lips.

• Severe lethargy or lack of response.

• Inability to intake fluids due to continuous vomiting.

• Blood in the stool or severe abdominal pain.

If any of these occur, please visit the nearest emergency room or urgent care center in your area.

How to cross-dose (alternate fever reducers):

Acetaminophen → wait 3 hours → Ibuprofen → wait 3 hours → Acetaminophen

(Ensure you strictly adhere to the maximum daily dosage limits for each medication).

Right now, preventing dehydration is your absolute priority. If your child refuses to drink fluids or if their energy levels drop further, please visit a hospital immediately.
