Prevacid (Lansoprazole)
Drug Uses
Prevacid is a proton pump inhibitor which prevents the stomach from producing acid. Prevacid is used to treat and forestall 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.
How Taken
Prevacid appears as an extended-release (long-acting) capsule to take it orally. Prevacid as a rule is taken once a day, before a meal. Take Prevacid exactly as directed. Take right the same often and in the same amount as that prescribed by your doctor. The capsule should be swallowed whole. If you have troubles 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 better. Do not stop taking Prevacid without talking to your doctor.
Drug Class and Mechanism
Prevacid 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. Prevacid, 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 permits the stomach and esophagus to cure.
Missed Dose
Take the missed dose as soon as you can. If it is almost time for your next dose, skip the missed dose and take the tablet at the next indirection scheduled time. Do not take additional medicine to make up the missed dose.
Storage
Keep Prevacid at room temperature. Store away from moisture and heat.
