People taking the medication omeprazole have been issued a warning by the NHS due to the long-term risks of the drug.
Omeprazole is a proton pump inhibitor (PPI) which decreases stomach acid production and is used to treat issues such as acid reflux and heartburn. It works by stopping the proton pumps which are enzymes located in the stomach wall that produce acid.
Recent figures show 73 million NHS prescriptions for proton pump inhibitors (PPIs), like Omeprazole, were dispensed in England between 2022-23. Additional data also shows PPI use affects around 15% of the population, making it one of the most commonly prescribed tables in the UK, the Mirror reports.
PPIs can also be used to treat other medical conditions including indigestion, healing of stomach ulcers, gastro-oesophageal reflux disease (GORD), and gastroesophageal reflux disease (GERD). It can also be used, alongside antibiotics, to treat the stomach infection Helicobacter pylori.

Common PPIs include Omeprazole (Prilosec), Esomeprazole (Nexium), Lansoprazole (Prevacid), Pantoprazole (Protonix), and Rabeprazole (AcipHex). Although they are effective, particularly for extended treatment periods, there are potential risks associated with long-term use.
The NHS has put out a warning about this on its website. The statement reads: “Do not take omeprazole for longer than two weeks if you bought it without a prescription. See a GP if your symptoms get worse or do not get better.”
One risk linked to long-term use of PPIs is a heightened risk of a bacterial infection known as Clostridioides difficile. This type of bacterium can lead to an infection in the intestines, resulting in diarrhoea and additional symptoms such as abdominal pain and fever.
This bacterium usually causes illness when antibiotics disturb the balance of normal gut bacteria, enabling Clostridioides difficile to grow and generate toxins. Symptoms include:
In most people, Clostridioides difficile exists harmlessly in the intestines alongside various other bacteria. However, when antibiotics eliminate the beneficial bacteria, they can quickly multiply. These toxins irritate the colon, resulting in infection symptoms.
Clostridioides difficile can be caused by medication disrupting the natural gut flora. It can also be transmitted via spores that endure on contaminated surfaces. It primarily impacts at-risk populations, including the elderly and people with compromised immune systems.
How to take omeprazole:
Omeprazole typically comes in tablets, capsules, and a liquid that you ingest. Certain tablets can be dissolved in water. The dosage and duration of treatment depend on the specific type of omeprazole you are using and the reason for its use. It is generally taken once or twice daily.
Some people may only require it for a few days, while others might need to continue for several weeks, months, or even years. Always refer to the packaging or leaflet that accompanies your medication. If you are uncertain about how to take it or encounter any issues, consult a pharmacist or doctor for guidance.

The NHS says: “Omeprazole will not usually affect your ability to drive, ride a bike or use machinery. But if you feel dizzy or have problems with your vision after taking it, wait until you no longer have these side effects.”
