11.Heartburn Remedies: H2 Blockers
Also available over-the-counter, H2 blockers work differently than antacids. Rather than zapping acids after they appear, these medications lower the production of stomach acid. This can help prevent heartburn from acid reflux if taken about 30 minutes before meals. More powerful doses are available in prescription form.
12.Acid Blockers: Proton Pump Inhibitors
Proton pump inhibitors, available over-the-counter and by prescription, are a class of drugs that block the production of stomach acid. They are more effective at decreasing acid production than H2 blockers.
