5. Which OTC (over-the-counter) product works the fastest if you have heartburn?
ANSWER: A. Antacids (TUMS®, Maalox®, etc.)
Antacids start working almost immediately once you’ve swallowed them, but the relief lasts the shortest amount of time. Therefore, if you have occasional heartburn, antacids work well. For more frequent symptoms, the longer-acting medications (like H2 blockers and PPIs) that you take once or twice per day are more appropriate.
