Cardbocisteine falls under a class of medicines called mucolytic that assist in coughing up phlegm. Both COPD and cystic fibrosis cause excessive phlegm production, which disrupts normal breathing. This medicine makes the mucus less sticky and hence easier to spit.


Carbocisteine is a mucolytic medication that is used to treat the problem of excessive mucus production in the lungs. It is prescribed to those who suffer from mucus in the lungs and other associated breathing problems. Carbocisteine works to dilute the mucus and make it easier to cough up. Usually, excessive mucus problems arise for people who have chronic obstructive pulmonary diseases (COPD), bronchitis, or cystic fibrosis. Carbocisteine is an effective remedy for dealing with sputum in the airways due to these conditions. This medicine is only available by prescription. It comes as capsules, syrup or liquid.

Carbocisteine is an effective remedy for excessive mucus in the lungs. It helps by making the sputum or mucus less sticky and easier to cough up. Usually, this medication is given to those who have chronic obstructive pulmonary disease (COPD), bronchitis, or cystic fibrosis.  Carbocisteine belongs to a group of medicines known as mucolytics. These medicines are designed to help reduce mucus, also known as phlegm or sputum, in the lungs for easier breathing.

In chronic obstructive pulmonary diseases (COPD), bronchitis, or cystic fibrosis, an excessive amount of thick mucus can collect in the airways, making it difficult for the patient to breathe. As this mucus is thick and sticky, it is difficult to remove by coughing up. The presence of sputum can block and irritate the airways.  

In such cases, doctors recommend Carbocisteine. This medication is a mucolytic, and it works by breaking the mucus down and making it less sticky. It allows the patient to cough up and remove the sputum that is constricting the airways.

Carbocisteine is a prescription-only medication and should be taken as per the dosage prescribed by your doctor. Your doctor will consider your age, medical history, the severity of your symptoms, and response to treatment before prescribing the required dose for you. Carbocisteine is available as a capsule, syrup, and liquid for ease of administration. Here is the usual recommended dose of Carbocisteine –  

For Adults 

  • Capsules: Two Carbocisteine 375 mg capsules, three times a day. When your symptoms improve, your doctor may lower your dosage to one Carbocisteine 375 mg capsules four times a day. Adults are usually prescribed capsules.  

  • SyrupCarbocisteine Syrup 15 ml, three times a day. When your symptoms improve, your doctor may lower your dosage to Carbocisteine Syrup 10 ml, three times a day. Syrup may be prescribed to children or adolescents. Paediatric syrups are also available. 

  • Liquid: One sachet of Carbocisteine liquid, three times a day. When your symptoms improve, your doctor may lower your dosage to one sachet of Carbocisteine liquid twice a day. The liquid form of Carbocisteine is usually given to children or people who cannot take capsules.
