Main Research Findings

Dexlansoprazole, a proton pump inhibitor (PPI), is a widely used medication to treat heartburn, acid reflux, and ulcers. Recent studies, however, have highlighted potential risks associated with dexlansoprazole, particularly regarding kidney and muscle health. 1 found a significant association between dexlansoprazole use and an increased risk of acute kidney injury (AKI) and chronic kidney disease (CKD). Furthermore, 6 reported cases of myopathy, a condition involving muscle weakness, linked to dexlansoprazole use.

5 identified a range of other potential side effects associated with dexlansoprazole, including pneumonia, Clostridium difficile infection, osteoporosis, fractures, thrombocytopenia (low platelet count), rhabdomyolysis (muscle breakdown), anemia, iron deficiency, hypomagnesemia (low magnesium levels), vitamin B12 deficiency, and nephritis (inflammation of the kidneys).

Reasons for side effects

The precise mechanisms by which dexlansoprazole contributes to these side effects are not fully understood. However, one proposed explanation is that by suppressing stomach acid, dexlansoprazole may disrupt the balance of bacteria in the gut, increasing susceptibility to infections. 5

Additionally, dexlansoprazole might interfere with magnesium absorption or influence bone metabolism, potentially increasing the risk of osteoporosis and fractures. 5

Common side effects

Digestive system

Dexlansoprazole may cause side effects affecting the digestive system, such as diarrhea, constipation, abdominal pain, nausea, and vomiting. 5

Infections

Dexlansoprazole might increase the risk of infections like pneumonia and Clostridium difficile infection. 5

Bones

Dexlansoprazole has been linked to an increased risk of osteoporosis and fractures. 5

Blood

Dexlansoprazole may lead to blood abnormalities, including thrombocytopenia, anemia, and iron deficiency. 5

Muscles

Dexlansoprazole has been associated with myopathy, a condition characterized by muscle weakness. 6

Kidneys

Dexlansoprazole use has been linked to a higher risk of AKI and CKD. 1

Other

Dexlansoprazole may cause additional side effects such as hypomagnesemia, vitamin B12 deficiency, and nephritis. 5

Managing side effects

Digestive system

To minimize digestive system side effects, lifestyle changes and dietary modifications are important. These include avoiding fatty foods, chewing thoroughly, reducing meal portions, and abstaining from alcohol and smoking.

Infections

To reduce the risk of infections, it is crucial to maintain good hygiene practices, such as frequent handwashing.

Bones

To lessen the risk of osteoporosis and fractures, it is essential to consume adequate calcium and vitamin D. Regular exercise is also beneficial.

Blood

To prevent blood abnormalities, regular blood tests are important. Increasing iron intake is also recommended.

Muscles

To help prevent muscle weakness, regular exercise is recommended.

Kidneys

Maintaining good kidney health involves staying well-hydrated. Regular health check-ups are also crucial.

Comparison across studies

Similarities

These studies collectively suggest a potential association between dexlansoprazole use and various side effects.

Differences

Each study focuses on specific aspects of dexlansoprazole's side effects. 1 primarily examined kidney effects, while 6 concentrated on muscle effects. 5 considered a broader range of potential side effects.

Real-life implications and cautions

Dexlansoprazole is an effective treatment for conditions like heartburn, acid reflux, and ulcers. However, it's essential to recognize the potential risks associated with its use. Particularly for long-term treatment, regular medical check-ups are crucial to monitor for side effects. If you experience any adverse reactions, consult your doctor promptly.

Limitations of current research

Research on dexlansoprazole's side effects is ongoing, and there is still much to learn. Further investigation is needed to understand long-term side effects and the influence of individual patient factors on side effect variations.

Future research directions

To gain a more comprehensive understanding of dexlansoprazole's side effects, the following research directions are essential:

• Investigating the mechanisms by which dexlansoprazole contributes to various side effects.
• Conducting studies to assess the long-term impact of dexlansoprazole use on side effects.
• Researching how individual patient factors influence the occurrence and severity of side effects.

Conclusion

Dexlansoprazole, while effective for treating heartburn, acid reflux, and ulcers, can potentially lead to various side effects. Follow your doctor's instructions carefully and report any side effects promptly. Continued research holds promise for a deeper understanding of dexlansoprazole's side effects, potentially leading to improved patient safety and outcomes.
