Contraindications to carbocisteine

Carbocisteine cannot be taken by anyone who is allergic to any of the ingredients contained in the medication, or people with active peptic ulcers (ulcers of the stomach or small intestine). Carbocisteine can cause problems in the elderly, those with a previous history of peptic ulcers or people currently taking medications that increase their risk of bleeding from the stomach or bowels. It is important that you let the prescribing doctor know if you have any health conditions, or take any medications. If you do experience any blood in your stool, or if you start vomiting blood, you should seek medical advice.

Why is carbocisteine contraindicated in peptic ulcer?

Carbocisteine is a mucolytic. This means that it breaks down mucus. It is designed to do this in the airways, however, it may have side effects in the gastrointestinal tract (oesophagus (food pipe), stomach and intestines). The gastrointestinal tract is protected by its own mucus. Therefore, if carbocisteine disrupts this protective mucus, the tissues may become more vulnerable to ulceration and bleeding.
