Omeprazole Users Warned of Potential Serious Side Effects

Individuals prescribed omeprazole, a common medication for stomach acid-related conditions, are being advised to be aware of potential serious side effects that may require immediate medical attention.

Omeprazole, a proton pump inhibitor (PPI), is widely used in the UK to treat heartburn, stomach ulcers, and gastro-oesophageal reflux disease (GERD) by reducing stomach acid production. It’s available in capsule, tablet, and liquid forms, and while generally not recommended for use exceeding two weeks without a prescription, doctors may prescribe it for longer durations depending on individual needs. Prolonged use of PPIs has been linked to nutrient deficiencies and other health concerns, prompting increased scrutiny of their long-term effects.

Common side effects of omeprazole include flatulence, nausea, vomiting, stomach pain, headache, constipation, and diarrhea. However, more serious side effects can occur, particularly with consistent use over a year or more, such as a lupus-like condition causing joint pain and rashes, weakened bones increasing fracture risk, and low vitamin B12 levels leading to fatigue and dizziness. A severe allergic reaction, anaphylaxis – characterized by a swollen tongue or throat, itchy rash, and difficulty breathing – also requires immediate attention. For more information on managing gastrointestinal health, resources are available at Mayo Clinic.

Health officials emphasize that anyone experiencing potentially serious side effects while taking omeprazole should contact 111 for guidance or seek an urgent appointment with their GP. You can find comprehensive details and guidance on omeprazole and its potential side effects on the NHS website.

The NHS continues to monitor reports of adverse reactions to omeprazole and will update guidance as needed.
