I'm sorry to hear that your fever hasn't improved after taking Calpol (paracetamol). Calpol is commonly used to reduce fever and relieve mild to moderate pain by acting on the brain's temperature regulation and pain pathways. However, if the fever persists despite taking it, it could indicate an underlying infection or other condition that needs further evaluation.

Here are some steps you can take:

• Monitor your symptoms: Keep track of your temperature and note any additional symptoms such as rash, difficulty breathing, severe headache, persistent vomiting, or confusion.
• Stay hydrated: Drink plenty of fluids to prevent dehydration.
• Rest: Allow your body to recover by resting adequately.
• Avoid self-medicating further without advice: Taking more medication without guidance may not be safe.

Since your fever has lasted for a day without relief, it is important to consult a doctor promptly to determine the cause and receive appropriate treatment. If you develop any severe symptoms or your condition worsens, seek emergency medical care immediately.

If you need urgent assistance, you can contact Apollo Emergency at 1066. Otherwise, please schedule an appointment with a general physician or an infectious disease specialist for a thorough evaluation.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
