What is lansoprazole:
Lansoprazole (Prevacid) decreases the amount of acid produced in the stomach.
Lansoprazole 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.
Lansoprazole may also be used for other purposes not listed in this medication guide
Important information about lansoprazole
Before taking lansoprazole, tell your doctor if you are allergic to any drugs, or if you have any type of liver disease. You may need a dose adjustment or special tests to safely take lansoprazole.
Some conditions are treated with a combination of lansoprazole and antibiotics. To best treat your condition, use all of your medications as directed by your doctor. Be sure to read the medication guide or patient instructions provided with each of your medications. Do not change your doses or medication schedule without advice from your doctor.
If you also take sucralfate (Carafate), avoid taking it at the same time you take lansoprazole. Sucralfate can make it harder for your body to absorb lansoprazole. Wait at least 30 minutes after taking lansoprazole before you take sucralfate.
Take lansoprazole for the entire length of time prescribed by your doctor. Your symptoms may get better before your treatment is completed.
Some forms of lansoprazole may contain phenylalanine. Tell your doctor if you have phenylketonuria.
How should I take lansoprazole:
Take lansoprazole exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.
Take each dose with a full glass (8 ounces) of water. Lansoprazole should be taken before eating. Do not crush or break a delayed-release capsule. Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking or opening the pill would cause too much of the drug to be released at one time.
If you are unable to swallow a lansoprazole delayed-release capsule whole: Open the capsule and sprinkle the medicine into a spoonful of pudding, applesauce, yogurt, cottage cheese, strained pears, or a nutritional drink such as Ensure. Swallow this mixture right away without chewing. Do not save the mixture for later use. Discard the empty capsule.
You may also dissolve the medicine from a lansoprazole capsule in 2 ounces (1/4 cup) of apple juice, orange juice, or tomato juice. Stir this mixture and drink all of it right away. To make sure you get the entire dose, add a little more juice to the same glass, swirl gently and drink right away.
