How long does it take for heartburn treatment to work?

ANSWER

The answer depends on whether you're about to try an over-the-counter antacid or a long-term prescription drug. Each heartburn treatment works differently, but in general:

Antacids like 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.
