Xanax (alprazolam) is not typically used to treat gastroesophageal reflux disease (GERD). While it may have a mild sedative effect that can help with anxiety-related symptoms that can contribute to GERD symptoms, there are more appropriate medications available to treat GERD. Xanax can also have side effects and risks associated with its use, such as addiction, dizziness, and drowsiness, among others. If you are experiencing GERD symptoms, it is recommended to talk to a doctor or healthcare professional to determine the most appropriate treatment options.
