Proper Use

Drug information provided by: Micromedex

Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. If you are using this medicine without a prescription, follow the instructions on the medicine label.

Take omeprazole capsules or delayed-release capsules before a meal, preferably in the morning. Omeprazole tablets may be taken with food or on an empty stomach. Take omeprazole powder for oral suspension on an empty stomach at least 1 hour before a meal. For patients receiving continuous feeding through a tube, feeding should be temporarily stopped about 3 hours before and 1 hour after administration of omeprazole powder for oral suspension.

It may take several days before this medicine begins to relieve stomach pain. To help relieve this pain, antacids may be taken with omeprazole, unless your doctor has told you not to use them.

If you are taking this medicine to treat an ulcer that is associated with an H. pylori infection, take it together with the antibiotics (e.g., amoxicillin, clarithromycin) at the same time of day.

Swallow the capsule and tablet forms of omeprazole whole. Do not open the capsule. Do not crush, break, or chew the capsule or the tablet.

If you cannot swallow the omeprazole delayed-release capsules, you may open it and sprinkle the pellets contained in the capsule on one tablespoon of applesauce. This mixture must be swallowed immediately with a glass of cool water. The applesauce should not be hot and should be soft enough to be swallowed without chewing. Do not chew or crush the pellets.

If you are using the delayed-release oral suspension with a nasogastric or gastric tube:

  • Add 5 mL to a catheter tipped syringe and then add the contents of a 2.5 mg packet (or 15 mL of water for the 10 mg packet).
