There are many over-the-counter medicines to relieve you from heartburn. You can choose from the following:
a. Antacids neutralize stomach acid and provide quick relief. However, the esophagus that might have been damaged by the stomach acid cannot be covered.
b. H-2-receptor antagonists or H2RAs do not act as quickly as antacids but they provide longer relief.
c. Proton pump inhibitors reduce stomach acids. Common examples are lansoprazole (Prevacid 24HR) and omeprazole (Nexium 24HR, Prilosec OTC).
