For your high fever, you can take Paracetamol (Acetaminophen) or Ibuprofen to help lower your temperature and ease body aches. For the dry cough, an over-the-counter cough suppressant containing Dextromethorphan can help quiet the cough reflex. Please rest, drink plenty of fluids, and consider taking a COVID-19 or flu test, as these are common causes. Avoid taking antibiotics without a prescription, as they do not treat viral infections. If your fever persists for more than three days, or if you experience shortness of breath, chest pain, or difficulty breathing, please seek immediate medical attention.
