NHS warns lansoprazole users: seek help immediately for rash, joint pain, or severe digestive symptoms.

The NHS is warning lansoprazole users to contact NHS 111 immediately if they develop a red, itchy rash or joint pain, as these could indicate a rare but serious condition called subacute cutaneous lupus erythematosus. Other concerning symptoms include severe or persistent diarrhea and worsening stomach pain, which may signal bowel, liver, or pancreas issues. While these serious side effects are rare, individuals should seek medical help without delay if they occur. Lansoprazole, used for heartburn and ulcers, is typically taken once or twice daily before meals. Patients should monitor for symptoms and consult a healthcare professional if concerned.
