For your symptoms, you can take Paracetamol (500mg) for the fever and body aches, up to three times a day after food. For a wet cough, an expectorant like Guaifenesin helps, while a dry cough benefits from Dextromethorphan. For nasal congestion, steam inhalation or a saline nasal spray is highly effective. Rest well and stay hydrated with warm fluids. Avoid taking antibiotics, as colds are viral and antibiotics will not help. If your fever lasts more than three days, or if you develop difficulty breathing, please consult a doctor in person immediately.
