 Drug Name
Prevacid (Lansoprazole)
Drug Uses
Prevacid decreases the amount of acid produced in the stomach. Prevacid 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. Prevacid may also be used for purposes other than those listed in this medication guide.
How Taken
Prevacid comes as an extended-release (long-acting) capsule to take it orally. Prevacid usually is taken once a day, before a meal. Take Prevacid exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. The capsule should be swallowed whole. If you have difficulty swallowing capsules, Prevacid can be opened, and the granules can be sprinkled on applesauce and swallowed immediately. The granules should not be chewed or crushed. Continue to take Prevacid even if you feel well. Do not stop taking Prevacid without talking to your doctor.
Drug Class and Mechanism
Lansoprazole is in a class of drugs called proton pump inhibitors (PPI) which block the production of acid by the stomach. Other drugs in the same class include rabeprazole (Aciphex), omeprazole (Prilosec), pantoprazole (Protonix), and esomeprazole (Nexium). Proton pump inhibitors are used for the treatment of conditions such as ulcers, gastroesophageal reflux disease (GERD) and Zollinger-Ellison Syndrome that are caused by stomach acid. Lansoprazole, like other proton-pump inhibitors, blocks the enzyme in the wall of the stomach that produces acid. By blocking the enzyme, the production of acid is decreased, and this allows the stomach and esophagus to heal.
Missed Dose
If you miss a dose of Cialis , take it as soon as you remember. Continue to use it as directed by your doctor.
Storage
Store Prevacid at room temperature away from moisture and heat.
