Health chiefs have issued a warning about long-term use of acid reflux drugs like omeprazole. The medication, widely prescribed for heartburn and indigestion, may raise the risk of a dangerous bacterial infection.
The NHS explained that prolonged use of proton pump inhibitors (PPIs) can upset the stomach’s natural balance. This makes patients more vulnerable to Clostridioides difficile (C. diff), a highly contagious bug that causes severe diarrhoea. “It kills up to one in five patients,” health officials warned.

Pharmacist Deborah Grayson added: “Omeprazole can help with gastritis, but for simple heartburn it may cause more harm long-term.” Reduced stomach acid not only weakens digestion but also lowers protection against harmful microbes.

The NHS advises: “Do not take omeprazole for longer than two weeks if you bought it without a prescription. See a GP if symptoms persist.” With C. diff cases in the UK rising sharply, experts say patients should think twice before relying on PPIs.
