NHS GP and TV doctor Amir Khan has issued a warning about the side effects of common medications, including Lansoprazole and Omeprazole, which are widely used for heartburn and acid reflux. In a recent Instagram post, he highlighted five commonly prescribed drugs and advised patients to seek medical advice if they experience any issues.
Key Advice on Medication Side Effects
Dr Khan emphasized that when prescribing medication, doctors weigh the benefits against the risks of side effects. He said: “When we prescribe medication, in our heads, we’re always weighing up potential benefits versus risk of side effects. And we only give them when the benefits outweigh any risk.” He urged patients not to stop taking their medication abruptly but to consult their doctor, as alternatives are often available.
He added: “But if you’re taking medication, having problems with them, don’t just stop taking them. Come and talk to us because we often have lots of alternatives that we can give you.”
Lansoprazole and Omeprazole: Nutrient Absorption Concerns
Focusing on Lansoprazole and Omeprazole, which are proton pump inhibitors (PPIs) that reduce stomach acid production, Dr Khan warned that long-term use could lead to reduced absorption of essential nutrients like vitamin B12 and magnesium. He said: “Brilliant medication for acid reflux and protecting the stomach, but if you’re taking them for months or years, they can reduce absorption of nutrients like vitamin B12 and magnesium. So they should be reviewed from time to time. Make sure you still need them and that you’re on the lowest possible dose to manage your symptoms.”
Other Medications Highlighted
Dr Khan also discussed metformin, commonly used for type 2 diabetes, which can cause stomach issues initially. He explained: “It works really well. But especially when you first start it, it can cause diarrhoea, bloating, stomach cramps, and nausea. For many people, these symptoms settle after a few weeks. So don’t lose hope too quickly, but there are alternatives should you need it.”
On ferrous sulfate (iron tablets), he noted: “These are the iron tablets. They’re fantastic at treating iron deficiency, but they can cause constipation, tummy discomfort, and nausea. And yes, they turn your poo black, but that’s expected. So, don’t panic about that one. If you’re struggling with them, come and speak to them. There’s liquid iron that we can prescribe for you.”
Regarding bisoprolol, used for high blood pressure and heart problems, he said: “We use this for things like high blood pressure. pressure, heart problems, and palpitations because it slows down the heart. Some people notice they’re more tired than usual, feel dizzy when they stand up, or have cold hands and feet. Come and talk to us.”
Asthma Inhaler Side Effects
Dr Khan also mentioned salbutamol inhalers, noting they can cause temporary shakiness or a racing heart. He said: “Make your hands feel a bit shaky or make your heart race for a short while after you’ve used it. That’s a well-recognised side effect. But if you’re needing your blue inhaler regularly, that’s actually a sign that your asthma may may not be as well controlled as it could be and it’s worth getting it reviewed. The most important thing is this. If you’re getting side effects from your medicine, don’t suffer in silence and don’t just suddenly stop taking them without speaking to your GP, nurse, or pharmacist. Very often, we can adjust the dose, change how you take it, or find an alternative that suits you better.”
In all cases, Dr Khan advised that any concerns should be discussed with a GP.
