====== Carbocysteine ====== Carbocysteine (INN), also known as Carbocisteine, is a medication used to loosen and thin mucus in the respiratory tract, which helps to reduce coughing and chest congestion. It is commonly used to treat upper and lower respiratory tract infections, chronic bronchitis, cystic fibrosis, and other conditions. Carbocysteine is available as an over-the-counter medication in many countries, and is a synthetic form of the amino acid cysteine. Carbocysteine works by breaking down the disulfide bonds that link mucin molecules in the lungs and bronchi, making them easier to cough up. Carbocysteine is typically taken by mouth as an oral solution or in tablet form. Carbocysteine has been used for many years to treat respiratory conditions, and is considered a safe and effective treatment. It is important to follow the instructions on the package or as prescribed by your doctor when taking carbocysteine. Following the recommended dosage it is normally well tolerated. ===== Contraindications ===== It is not suitable for children under 3 years of age, because their airways are not yet developed enough. ===== Side effects ===== Possible side effects of carbocysteine, specially in case of overuse, include nausea, vomiting, diarrhea, and abdominal pain. More serious side effects include difficulty breathing, chest pain, and an increased risk of bleeding. Carbocysteine should not be taken by people with kidney or liver disease, or those who have a history of bleeding disorders. It may interact with certain medications, and it is important to tell your doctor about any other drugs, supplements, or herbal products you are taking before using carbocysteine. ===== See also ===== N-acetylcysteine /* Guaifenesin */ {{page>en/medical-disclaimer}}
