Gelusil® (ANTACID & ANTI-GAS) works with 24-hour heartburn medications like Nexium®, Prevacid®, and Prilosec OTC®.

24-hour heartburn medications, also known as PPI (proton pump inhibitor) acid reducers, are available by prescription or over the counter and are designed to provide long-lasting relief. Nexium®, Prevacid®, Prilosec OTC®, and other PPI acid reducers are taken daily, usually for 14 days, to reduce stomach acid and control the symptoms of acid reflux. But sometimes, breakthrough heartburn occurs when symptoms appear before it's time to take the next dose. A rescue treatment is necessary.

Gelusil® is the #1 rescue treatment for immediate heartburn relief.* While it shouldn't replace your PPI acid reducer, it can be used between doses to provide fast relief when heartburn or acid indigestion flares up. It's safe to use with Nexium®, Prevacid®, Prilosec OTC®, and other 24-hour heartburn medications — so you don't have to wait to get relief.

Gelusil® is different from Tums® and Rolaids®.

Gelusil® has different active ingredients than other antacids. Unlike Tums® and Rolaids®, it doesn't contain calcium carbonate, which is an ingredient that has been shown to be associated with acid rebound. Gelusil® is also an anti-gas medication, so it relieves bloating, flatulence, and belching.

In clinical studies, Gelusil® was used more than all other traditional antacids on patients who needed a rescue antacid while taking a PPI acid reducer.*

Across America, Gelusil® was chosen by researchers, physicians, and other healthcare professionals to administer to patients who participated in PPI acid reducer clinical studies. Because Gelusil® was used most often for these cases of breakthrough heartburn, you may want to try it on yours.
