If you have a cough, you should rest, drink plenty of fluids, and try to stay home to avoid spreading infection, especially if you have a fever or feel unwell. Drinking warm fluids like hot lemon and honey can soothe your throat. Using cough medicines like paracetamol or ibuprofen may help with pain, but always check safety if pregnant or for children. Steam from a hot shower or a humidifier can help loosen mucus. Avoid smoking and irritants. If you have persistent cough lasting more than a few weeks, green/yellow phlegm, fever over 102°F, bloody cough, or difficulty breathing, seek medical advice promptly.
