Unexpected Facts About Omeprazole That Will Blow Your Mind

19. It’s on the World Health Organization’s List of Essential Medicines

Despite its potential risks, omeprazole is considered one of the most important medications in the world. It is listed on the World Health Organization’s (WHO) Model List of Essential Medicines, which highlights critical drugs needed for a functioning healthcare system. This recognition underscores omeprazole’s importance in treating acid-related conditions globally, particularly in countries where severe ulcers and acid reflux are widespread.

20. It Has an Unusual Connection to Helicobacter Pylori

Omeprazole isn’t just used to treat acid reflux—it also plays a key role in eradicating H. pylori infections, which are a major cause of stomach ulcers. When combined with antibiotics, omeprazole suppresses acid production, making it easier for the antibiotics to kill the bacteria. Interestingly, H. pylori infections can also alter stomach acid production over time, sometimes leading to acid reflux or ulcers even after the infection is gone. This makes omeprazole’s role in treatment even more significant.
