What Is Omeprazole?

Omeprazole is a proton pump inhibitor (PPI) that reduces stomach acid production. Doctors often prescribe it for:

• Acid reflux and heartburn
• Indigestion
• Stomach ulcers and duodenal ulcers
• Zollinger–Ellison syndrome (a rare condition with excessive stomach acid)

It is available both on prescription and over the counter in the UK under brand names like Losec and generic versions.

Why the NHS Issued Warnings About Omeprazole

The NHS provides guidance to ensure patients take omeprazole safely. Some of the main warnings include:

1. Long-Term Use Risks

• Taking omeprazole for more than a year may increase the risk of bone fractures, especially in the hip, wrist, or spine.
• It may also reduce levels of magnesium and vitamin B12, leading to fatigue, dizziness, or tingling sensations.

2. Kidney Problems

Some patients on long-term omeprazole have developed kidney inflammation. Symptoms include blood in urine, pain when urinating, or swelling.

3. Risk of Stomach Infections

By lowering stomach acid, omeprazole may make you more vulnerable to infections like Clostridium difficile (C. diff), which can cause severe diarrhea.

4. Possible Heart Concerns

Studies have suggested long-term use may affect heart health, especially if taken with certain other medicines.

5. Masking Serious Conditions

While omeprazole relieves symptoms, it can hide serious problems such as stomach cancer by reducing warning signs like persistent indigestion.

Not everyone can safely take omeprazole. The NHS advises caution for people who:

• Have liver problems

Omeprazole and Other Medications

The NHS omeprazole warning also highlights possible drug interactions. Omeprazole may interfere with medicines such as:

To minimize risks, the NHS provides clear guidelines:

1. Follow the prescription – Take the exact dose your doctor recommends.
2. Timing matters – Usually taken once daily in the morning, 30 minutes before food.
3. Short-term use – Use the lowest effective dose for the shortest time possible.
4. Lifestyle changes – Combine treatment with a healthy diet, reduced alcohol, quitting smoking, and weight management for best results.

NHS Warning: Do Not Stop Suddenly

Stopping omeprazole suddenly can cause acid rebound, where stomach acid production increases sharply, leading to worse heartburn or indigestion.

If you need to stop, your doctor may recommend tapering down the dose gradually.

---

If omeprazole is not suitable, the NHS may suggest alternatives such as:

• Other PPIs: Lansoprazole, esomeprazole, pantoprazole
• H2 blockers: Ranitidine (less common now), famotidine
• Lifestyle changes: Avoiding spicy foods, caffeine, late meals, and maintaining a healthy weight
