Make sure to keep your doctor informed about your liver health, as they may need to conduct regular tests to ensure your safety while using any medication. Your well-being is a priority, so don't hesitate to ask questions or express any concerns you may have.

Drug Interactions

It's important to be aware that antacids, which are commonly used to relieve heartburn and indigestion, can interact with some prescription medications. This means that taking antacids at the same time as certain drugs may affect how well those medications work.

To ensure your safety and the effectiveness of your treatment, always discuss any medications you are taking, including over-the-counter products like antacids, with your healthcare provider. They can help you understand potential interactions and adjust your treatment plan if necessary.
