For fever and body pain, you can take paracetamol as directed. For cold symptoms, an antihistamine like cetirizine can help. For a dry cough, a cough suppressant containing dextromethorphan is useful, while an expectorant like guaifenesin helps with a wet cough. To recover from weakness, prioritise plenty of rest and stay well-hydrated with water or oral rehydration solutions. These symptoms are very common and typically improve with self-care. However, if your symptoms persist for more than a few days, worsen, or if you develop breathing difficulties, please consult a doctor for a proper evaluation.
