Gaviscon is generally considered safe for the kidneys and does not directly affect kidney function. It primarily works by forming a protective layer over the stomach lining, preventing acid reflux and heartburn.
However, it's important to note that certain ingredients in Gaviscon, like aluminum hydroxide, can potentially contribute to aluminum accumulation in the body over time. While this is not a common occurrence, it might be a concern for individuals with pre-existing kidney problems or those taking other medications that could affect kidney function.
It's always best to consult with your doctor or pharmacist if you have any concerns about Gaviscon or any other medication affecting your kidneys. They can provide personalized advice based on your medical history and current medications.
