Have mucus in my lungs. what medication do i need? mucus from a head cold

Mucus: If your symptoms are more than a week old and you are raising large amounts of discolored sputum, it's likely that the viral upper respiratory tract infection has morphed into a bacterial bronchitis. If so a course of antibiotics would be helpful in reducing the duration and intensity of your infection. Otherwise good fluid intake and expectorant syrup would help.
