What is Prevacid SoluTab?

Prevacid SoluTab is a proton pump inhibitor. This medicine decreases the amount of acid produced in the stomach.

Prevacid SoluTab is used to treat and prevent stomach and intestinal ulcers, erosive esophagitis (damage to the esophagus from stomach acid), and other conditions involving excessive stomach acid such as Zollinger-Ellison syndrome.

Over-the-counter Prevacid SoluTab (Prevacid OTC) is used to treat frequent heartburn that happens 2 or more days per week.

Prevacid SoluTab is not for immediate relief of heartburn symptoms.

Prevacid SoluTab may also be used for purposes not listed in this medication guide.
