Question:
My child had a fever this morning, so we visited the doctor. They didn't do a flu test but diagnosed my child with tonsillitis and prescribed general cold medicine and antibiotics. My child is eating small amounts occasionally, but they just keep lying down or sleeping. Their temperature was over 38°C (100.4°F), so I gave them a fever reducer (Dexibuprofen) at 5 PM. They have only urinated once today. Should we go to the emergency room if their urine output is this low?
Answer:
Hello. I understand you must be very worried since your child is quite sick and showing signs of lethargy and decreased urination after being diagnosed with tonsillitis.
Here is an assessment of your child's current condition:
A fever over 38°C (100.4°F) is an expected symptom of tonsillitis.
Administering a fever reducer was the appropriate step to take.
It is a very positive sign that your child is still able to eat small amounts.
However, sleeping continuously and having a low urine output require close observation.
Please check the following signs of dehydration at home:
Note exactly how many hours it has been since their last urination.
Examine their lips and the inside of their mouth to see if they are dry.
Check if they produce tears when they cry.
⚠️ You should go to the Emergency Room if you notice any of the following:
No urination for more than 8 hours.
Severely dry lips or tongue.
Crying without producing any tears.
Extreme lethargy, making them very difficult to wake up.
Difficulty breathing.
What you can do right now:
Offer 1 to 2 sips of water or an electrolyte/sports drink every 5 to 10 minutes to maintain hydration.
Offering their favorite beverages or ice cream is also a good way to encourage fluid intake right now.
Recheck their temperature about an hour after administering the fever reducer.
Let them rest naturally without forcefully waking them up, but continue to observe their breathing and responsiveness closely.
It typically takes about 24 to 48 hours for antibiotics to take full effect. For now, focus on maintaining their fluid intake and keeping them comfortable. If their urine output remains consistently low, or if their energy levels drop further and they become unresponsive, please visit the emergency room immediately for an in-person evaluation.
