Buying advice

Consider your specific needs: for quick relief of occasional heartburn, antacids like Rolaids or Tums work well; for nausea, Pepto-Bismol is a good choice; for long-lasting relief or prevention, Gaviscon, Pepcid, or Nexium may be better. Check ingredient sensitivities (e.g., calcium vs. magnesium) and choose based on flavor, form (chewable, liquid, tablet), and desired speed of action.
