The incidence of diarrhea as a side effect increases with an increase in dosage. Lansoprazole heals active duodenal ulcers, and is useful in conditions that cause excessive stomach acid production such as Zollinger-Ellison syndrome. Generic lansoprazole capsules are not yet available. Take lansoprazole capsules by mouth. Follow the directions on the prescription label.
Lansoprazole works best if taken on an empty stomach.
It is best to take the capsules 30 to 60 minutes before food. Take your doses at regular intervals. Do not take your medicine more often than directed. Elderly patients should not take more than 30 mg of lansoprazole per day. If you miss a dose, take it as soon as you can.
