It is recommended that capsules be taken before meals for maximum effect. Capsules should be swallowed whole and should not be crushed, split or chewed.

For those with difficulty swallowing, the capsule should be opened and the granular contents sprinkled on a tablespoon of apple sauce, ENSURE pudding, cottage cheese, yogurt or strained pears and swallowed immediately. Granules also may be mixed in two ounces (60 ml) of apple, orange or tomato juice and swallowed immediately. For patients with a nasogastic tube, mix the granules can be mixed in two ounces of apple juice and injected through the nasogastric tube.

Which drugs or supplements interact with lansoprazole?

Lansoprazole is less likely than omeprazole (Prilosec, Zegerid) to interact with other drugs.

The absorption of certain drugs may be affected by stomach acidity, and, as a result, lansoprazole and other PPIs that reduce stomach acid also reduce the absorption and concentration in blood of ketoconazole (Nizoral) and increase the absorption and concentration in blood of digoxin (Lanoxin). This may lead to reduced effectiveness of ketoconazole or increased digoxin toxicity, respectively.

Lansoprazole may increase blood levels of methotrexate (Trexall) and tacrolimus (Prograf).

Proton pump inhibitors may also increase the action of warfarin (Coumadin), increasing the risk of bleeding.
