1. What Mucodyne Capsules are and what they are used for

Mucodyne 375mg Capsules, Hard (called Mucodyne Capsules in this leaflet) contain a medicine called carbocisteine. This belongs to a group of medicines called ‘mucolytics’. It works by making mucus (phlegm) less sticky. This makes the mucus easier to cough up. Mucodyne Capsules are used for problems with the breathing passages (respiratory tract). These problems happen when too much mucus is made or the mucus is too sticky.
