If you have a fever and headache, taking Pyrigesic 500 (Paracetamol 500 mg) is generally safe and effective for reducing fever and relieving pain.

• Dosage: The usual adult dose is 500 mg to 1,000 mg every 4 to 6 hours as needed, but do not exceed 4,000 mg (4 grams) in 24 hours.

• How to take: You can take it with or without food, preferably with meals. If you miss a dose, take it as soon as you remember unless it is close to the next dose.

• Precautions: Avoid taking other medications containing paracetamol at the same time to prevent overdose. Also, avoid alcohol as it may increase the risk of liver damage. If you have any liver issues, malnutrition, or dehydration, consult a doctor before use.

• When to seek medical advice: If your fever lasts more than 3 days, worsens, or you develop new symptoms such as rash, difficulty breathing, or severe headache, please see a doctor promptly.

Since you tested negative for malaria, Pyrigesic can help manage your symptoms while you monitor your condition. However, if symptoms persist or worsen, further evaluation by a doctor is important to rule out other causes of fever and headache.
