If you suffer from acid reflux, several over-the-counter medications can be used to suppress the symptoms, including Tagamet, Zantac, and Pepcid. Common brand-name antacids such as Gaviscon, Maalox, Mylanta, and Tums can also be effective. However, if you take antacids more than four times a week to control your symptoms, you must seek medical advice from a physician.
