Prevacid is an oral capsule consisting of a proton pump inhibitor called lansoprazole. We carry this medication in both the brand choice and generic alternative in 15mg and 30mg!

Prevacid is a medication used to treat and prevent stomach and intestinal ulcers, damage to the esophagus from stomach acid called erosive esophagitis, and other conditions associated with an excessive amount of stomach acid production such as Zollinger-Ellison syndrome.  In these conditions, inflammation, irritation, or swelling occurs which causes pain and discomfort; however with medications like Prevacid, these symptoms can be treated.

Prevacid is effective at treating and prevent stomach and intestinal ulcers because lansoprazole is able to decrease the amount of stomach acid being produced in the stomach which results in these conditions healing faster and less likely to reoccur.

It is important to follow directions given to you by your doctor. Directions can be found on your prescription label if you forget; contact your doctor if you are still unsure how to take this medication.
