Medication Consultation


I have been prescribed stomach medication at the clinic for a few weeks, including a medication called "Omezol" (Omeprazole) 20 mg capsules, which I am supposed to take once daily.
However, I accidentally took it three times a day for the past few days.
Doctor, what effects might this have on my body? I am very concerned about my health.

According to the package insert for Yao Ning capsules, excessive intake may result in symptoms such as nausea, vomiting, dizziness, abdominal pain, diarrhea, and headache.
However, these symptoms are typically temporary.
If you have concerns, please consult your physician.
Thank you.

More Info


When it comes to the use of Omezol (omeprazole), a proton pump inhibitor (PPI) commonly prescribed for conditions like gastroesophageal reflux disease (GERD) and peptic ulcers, it is essential to understand both its therapeutic benefits and potential risks associated with overuse.
Omezol works by reducing the amount of stomach acid produced, which can help alleviate symptoms of acid reflux and promote healing of the esophagus and stomach lining. However, like any medication, it is crucial to adhere to the prescribed dosage to minimize the risk of adverse effects.

In your case, taking Omezol three times a day instead of the prescribed once daily can lead to several potential health concerns. While short-term overuse may not immediately result in severe side effects, prolonged excessive use can lead to more significant issues.

1. Nutrient Absorption: One of the primary concerns with long-term use of PPIs like Omezol is the potential for nutrient malabsorption. Stomach acid plays a crucial role in the absorption of certain vitamins and minerals, particularly vitamin B12, calcium, magnesium, and iron. Overuse of Omezol can lead to deficiencies in these nutrients, which may result in symptoms like fatigue, muscle cramps, or bone density loss.

2. Bone Health: There is evidence suggesting that long-term use of PPIs may be associated with an increased risk of osteoporosis and fractures. This is particularly concerning for individuals who may already be at risk for bone density loss. If you have been taking Omezol excessively, it would be wise to discuss your bone health with your healthcare provider.

3. Gastrointestinal Issues: Overuse of PPIs can also lead to gastrointestinal problems, including an increased risk of Clostridium difficile infection in the colon, which can cause severe diarrhea and colitis. This risk is particularly pronounced in older adults or those with weakened immune systems.

4. Kidney Health: Some studies have indicated a potential link between long-term PPI use and chronic kidney disease. While the exact mechanism is not fully understood, it is a concern that should be monitored, especially if you have any pre-existing kidney issues.

5. Rebound Acid Hypersecretion: If you suddenly stop taking Omezol after prolonged use, you may experience rebound acid hypersecretion, where your stomach produces even more acid than before, leading to a return of symptoms. This can create a cycle of dependency on the medication.

Given your situation, it is advisable to consult with your healthcare provider as soon as possible. They can assess your current health status, review your medication regimen, and determine if any adjustments are necessary. They may recommend monitoring your nutrient levels, particularly if you have been taking Omezol excessively for an extended period.

In the meantime, it is essential to avoid further overuse of the medication. Stick to the prescribed dosage and consider discussing alternative strategies for managing your symptoms, such as dietary changes, lifestyle modifications, or other medications that may be more appropriate for your condition.

In summary, while Omezol can be an effective treatment for acid-related disorders, overusing it can lead to various health issues. It is crucial to follow your healthcare provider's instructions and communicate any concerns you may have regarding your medication and overall health.
