Question: what is the best medicine for severe heartburn?
Answer: If your symptoms strike less often, use a fast-acting over-the-counter antacid such as Maalox, Mylanta, Rolaids, or Tums. Or try an over-the-counter H2 blocker, such as famotidine (Pepcid AC) or ranitidine (Zantac 75). They tend to cause fewer side effects and are typically cheaper than PPIs.
