I don't think prevacid works best when it's given with food.

Here's some other info on Prevacid
Prevacid® (Lansoprazole) - In addition, an oral suspension formulation of lansoprazole (Prevacid®) was FDA-approved in January 2002. The new formulation is available as 15 mg and 30 mg strawberry-flavored packets. These packets are mixed with 2 tbsp of water just prior to ingestion. Mixing with other liquids or foods is not recommended.
Studies have shown that lansoprazole suspension is stable for 8 hours at room temperature (22° C) and for 14 days when refrigerated (4° C).
ORAL ADMINISTRATION
The enteric-coated granules of lansoprazole can be mixed with soft foods or acidic juices.
Soft foods: Empty the enteric coated granules of 1 lansoprazole capsule onto a tablespoon of applesauce, ENSURE pudding, cottage cheese, yogurt, or strained pears and administer immediately (within 30 minutes) without crushing or chewing the granules.
Juices: Granules can also be mixed with 60 ml (2 ounces) of either apple, cranberry, grape, orange, pineapple, prune, tomato, or V-8 vegetable juice and administered immediately (within 30 minutes) as long as the granules are not crushed or chewed.
Suspension for administration through gastric tube:
Administer the suspension through a gastric tube and flush with 10 mL of tap water.
Administration of the granules through a naso-gastric/gastrostomy tube:
The enteric-coated granules can also be administered through a gastric tube. According to the packet insert, the contents of 1 lansoprazole capsule can be mixed with 40 ml of apple juice and injected into a nasogastic tube. The tube should then be flushed with additional apple juice, so as to assure the complete delivery of the dose.
