NHS GP Dr Amir Khan has issued a warning to patients taking proton pump inhibitors (PPIs) such as omeprazole, lansoprazole, and pantoprazole. Speaking on ITV's Lorraine, Dr Khan advised that these medications should never be stopped abruptly due to the risk of rebound acid reflux.
Dr Khan explained that while PPIs are effective at reducing stomach acid and treating heartburn, long-term use can lead to deficiencies in vitamin B12, magnesium, and iron. These deficiencies may cause brain fog, anaemia, tiredness, and nerve problems.
The doctor urged patients to ask their GP a simple question: “Are you on the lowest possible dose to maintain your symptoms?” He also suggested asking whether taking the medication on alternate days could be an option to reduce side effects while controlling symptoms.
Dr Khan emphasised that patients have the right to request a medication review appointment, which can be conducted in person, by phone, or via online consultation. Patients should prepare by listing all prescriptions, over-the-counter medicines, and any side effects they are experiencing.
