I'm sorry to hear your child is still experiencing fever despite treatment. It's good that the cold symptoms have improved with Maxtra P syrup, which contains paracetamol, a decongestant, and an antihistamine. Calpol syrup, which also contains paracetamol, helps reduce fever temporarily, but if the fever returns after 5 hours, it suggests the underlying cause may still be active.

Here are some important points and steps you can take:

• Monitor the fever closely: Keep track of the temperature and note how long the fever lasts and any other symptoms such as lethargy, irritability, difficulty breathing, or poor feeding.
• Follow dosing instructions carefully: Ensure you are giving the correct dose of paracetamol (Calpol) based on your child's weight and not exceeding the recommended frequency (usually every 4-6 hours, not more than 4 doses in 24 hours).
• Hydration and comfort: Make sure your child stays well hydrated and rests comfortably.
• When to seek medical care: If the fever persists beyond 3 days, is very high (above 39°C or 102.2°F), or if your child shows signs of distress, difficulty breathing, persistent vomiting, rash, or decreased responsiveness, you should consult a pediatrician promptly.

Since your child’s fever is persistent despite medication, I recommend consulting a pediatrician to evaluate for any underlying infection or other causes that may require specific treatment.

If you notice any emergency signs like difficulty breathing, seizures, or unresponsiveness, seek emergency care immediately.
