Long-term Use of Prevacid: Risks and Benefits

When considering the long-term use of Prevacid, it is essential to weigh both the risks and benefits associated with this medication. While Prevacid is effective in treating conditions such as gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome, prolonged use may pose certain risks.

  • Nutritional Deficiencies: Chronic use of Prevacid can also affect the absorption of essential nutrients such as vitamin B12, magnesium, and iron. This can lead to deficiencies that may cause various health problems.
  • Renal Impairment: Some studies have suggested a potential link between long-term PPI use and kidney damage. Individuals with pre-existing kidney conditions may be at higher risk.
  • Increased Risk of Infections: Long-term use of Prevacid has been associated with an increased risk of infections, particularly Clostridium difficile (C. diff) and pneumonia.
