How quickly do antacids work?
Each heartburn treatment works differently, but in general: Antacids like Rolaids or Tums work instantly, but wear off quickly. Antacids work best if taken 30 to 60 minutes before eating. Histamine blockers take effect in about an hour, but must be taken twice a day for heartburn prevention.Jun 9, 2024
