In millions of homes, omeprazole has become a familiar after-dinner companion. Many take it before a heavy meal as a supposed “gastric protector.” However, specialists warn that this indiscriminate use can conceal significant health risks.
According to the U.S. National Library of Medicine, omeprazole belongs to the group of proton pump inhibitors (PPIs), drugs that reduce stomach acid production.
Thanks to this action, it is prescribed to treat gastroesophageal reflux disease (GERD), gastric or duodenal ulcers, Zollinger-Ellison syndrome, and, in combination with antibiotics, to eradicate the Helicobacter pylori bacteria.
How does omeprazole actually work?
This medicine works by blocking an enzyme called H+/K+ ATPase in the parietal cells of the stomach.
By reducing acidity, it provides relief from heartburn, reflux, or gastric mucosal lesions. Due to its effectiveness, it has become the most prescribed drug for acid-related digestive disorders.
Precise medical indications
Institutions such as the UNAM School of Medicine and the University of Navarra Clinic indicate that omeprazole is useful in:
- GERD: to reduce burning and prevent esophageal damage.
- Gastric and duodenal ulcers: promotes healing.
- Zollinger-Ellison syndrome: controls overproduction of acid.
- Helicobacter pylori eradication: in combination therapy.
- Prevention of NSAID ulcers in patients who chronically use anti-inflammatory drugs.
However, doctors insist that it should only be used under professional supervision.
Is it safe to take it every day?
Omeprazole is considered safe for short courses of treatment, usually four to eight weeks. The problem arises when consumption continues for a long time without medical supervision. In older adults or patients with chronic illnesses, periodic evaluation is essential to assess whether the benefits outweigh the risks.
Risks of prolonged use
Research from the University of Navarra Clinic points to adverse effects linked to extensive treatments, such as:
- Vitamin B12 deficiency.
- Loss of bone density and increased risk of fractures.
- Intestinal infections caused by bacteria such as Clostridium difficile.
- Alterations in the absorption of essential minerals.
- Kidney or liver damage.
Pregnancy, children, and misuse
During pregnancy, omeprazole is only prescribed if the doctor deems it necessary. In children, it is administered in severe cases of reflux or erosive esophagitis, always adjusting the dose according to weight.
Although it is popularly called a “gastric protector,” the term is incorrect: the medication does not protect the stomach, but rather suppresses acid production, also affecting digestion and part of the body’s natural defenses.
When to avoid omeprazole
Its use should be avoided or previously discussed in cases of severe liver failure, vitamin B12 deficiency, treatment with certain anticoagulants or antiretrovirals, or allergy to other PPIs.
Natural options and habit changes
For mild bouts of heartburn, doctors recommend simple measures first: moderate fatty or spicy foods, avoid lying down after eating, maintain a healthy weight, and incorporate mild herbal teas such as chamomile or ginger.
Omeprazole is effective and safe when used appropriately and with clinical judgment. The problem arises when it becomes a daily self-medication to mask symptoms. Instead of taking it “just in case,” specialists insist on seeing a doctor to treat the real cause of the discomfort.
