What is breakthrough heartburn?

In an independent study, 46% of people on 24-hour medications like Nexium® or Prevacid® (acid reducers also known as proton pump inhibitors, or PPIs) experienced heartburn or acid indigestion between doses.1 This is also known as breakthrough heartburn because symptoms reappear — or break through — before it's time for another dose. If your PPI acid reducer occasionally stops controlling symptoms and heartburn flares up, you need another way to get fast relief.

Gelusil® is the brand of antacid used most often to relieve breakthrough heartburn symptoms in PPI acid reducer clinical studies. It's the #1 rescue treatment for immediate heartburn relief* — which means it can provide additional control of heartburn and acid indigestion between doses of your 24-hour heartburn medication.

Gelusil® provides breakthrough heartburn relief.

Most PPI acid reducers can only be taken every 24 hours. Sometimes for severe heartburn sufferers, that's not enough, and more relief is needed between doses. If this happens to you and heartburn occurs before it's time for another dose of your PPI, Gelusil® is safe to use with Nexium®, Prevacid®, Prilosec OTC®, and other 24-hour heartburn medications. Gelusil® works in seconds to soothe heartburn, calm acid indigestion, and reduce discomfort and bloating caused by gas.

If you experience breakthrough heartburn, you're not alone. In an independent study, nearly one in two people on a 24-hour acid reducer needed a rescue treatment.1 Take Gelusil®, and talk to your doctor.

What is acid rebound?

Acid rebound is when a large amount of stomach acid rises into the esophagus several hours after taking an antacid. Acid rebound occurs most often with antacids that contain calcium carbonate.2

Gelusil® doesn't contain calcium carbonate and hasn't been shown to be associated with acid rebound.3
