- Itchy red skin rash and joint pain which could indicate a condition known as subacute cutaneous lupus erythematosus
- Severe or persistent diarrhoea which could be a sign of an inflamed bowel
- Stomach pain that gets worse which could indicate an inflamed liver or pancreas
Stomach pain can also be a common side effect that affects more than one in 100 people taking lansoprazole. While this pain may be minor in some cases, the NHS cautions that if you experience stomach pain that seems to be worsening, then you should call a doctor or dial 111.
The report emphasises that such stomach discomfort “can be a sign of an inflamed liver or pancreas”. Additionally, if you experience severe or frequent diarrhoea while taking the PPI, it could indicate an inflamed bowel.
