From the Research

If you have elevated creatinine levels, you should consult your healthcare provider before taking Gaviscon, as it contains aluminum hydroxide, which can accumulate in the body when kidney function is impaired, potentially leading to aluminum toxicity. Elevated creatinine indicates reduced kidney function, which affects how your body processes and eliminates medications. While Gaviscon is generally considered safe for most people, the aluminum content poses specific risks for those with kidney problems 1. Your doctor may recommend an alternative antacid that doesn't contain aluminum, such as calcium carbonate-based products. The specific recommendation will depend on your creatinine level, overall kidney function, and other medications you may be taking.

Key Considerations

  • The aluminum content in Gaviscon can accumulate in the body when kidney function is impaired, potentially leading to aluminum toxicity 1.
  • Elevated creatinine levels indicate reduced kidney function, which affects how your body processes and eliminates medications.
  • Alternative antacids that don't contain aluminum, such as calcium carbonate-based products, may be recommended by your doctor.
  • Non-medication approaches, such as dietary changes, avoiding eating before bedtime, and elevating the head of your bed, may also be suggested by your doctor if you're experiencing heartburn or acid reflux and have kidney issues.

Relevant Studies

  • A study published in 2022 found that trimethoprim can affect the kinetics of creatinine, sodium, and potassium in the proximal and distal tubules in a dose-dependent manner without changing the glomerular filtration rate 1.
  • However, this study does not directly address the safety of Gaviscon in patients with elevated creatinine levels.
  • Other studies, such as those published in 2019,2001,1995, and 2003, do not provide relevant information on the safety of Gaviscon in patients with impaired renal function 2, 3, 4, 5.

Recommendation

It is essential to consult your healthcare provider before taking Gaviscon if you have elevated creatinine levels, as they can assess your individual situation and provide personalized advice on the safe use of antacids. Your doctor may recommend alternative treatments or adjustments to your medication regimen to minimize the risks associated with impaired renal function.
