Omeprazole (By mouth)

Introduction:

Omeprazole (oh-MEP-ra-zole)

Treats heartburn, stomach ulcers, gastroesophageal reflux disease (GERD), and conditions that cause your stomach to make too much acid (such as Zollinger-Ellison syndrome, endocrine tumors, and systemic mastocytosis). It also helps heal the esophagus when the stomach makes too much acid and helps prevent bleeding in the stomach for patients with a serious illness. This medicine may be used in combination with antibiotics, such as clarithromycin and amoxicillin, to treat certain types of ulcers.

How to Use This Medicine:

Delayed Release Capsule, Packet, Powder for Suspension, Delayed Release Tablet

  • Your doctor will tell you how much of this medicine to use and how often. Do not use more medicine or use it more often than your doctor tells you to.
  • It is best to take this medicine before a meal.
  • Swallow the delayed-release capsule or delayed-release tablet whole. Do not crush, break, or chew it. If you cannot swallow the delayed-release capsule, you may open it and pour the medicine into a small amount of soft food, such as applesauce. Stir this mixture well and swallow it without chewing. Drink a full glass (8 ounces) of cool water to make sure you swallow all of the medicine.
  • If you are using the oral suspension, add the contents of the packet into a container with 1 teaspoonful of water (2.5 mg packet) or 3 teaspoonfuls of water (10 mg packet) and stir well. Let the mixture sit to thicken for 2 to 3 minutes. Then stir it again and drink it within 30 minutes. If any mixture is left in the container, add more water, stir, and drink the water right away.
  • The oral suspension may also be given through a nasogastric or gastric feeding tube. Add 1 teaspoonful of water (2.5 mg packet) or 3 teaspoonfuls of water (10 mg packet) to a catheter tipped syringe. Add the contents of the packet to the syringe and shake the mixture right away. Let the mixture sit to thicken for 2 to 3 minutes. Shake the syringe again and inject it into the nasogastric or gastric tube within 30 minutes. Put the same amount of water in the syringe again, shake it, and then flush the tube to rinse all of the medicine from the tube into the stomach.
  • If you are using this medicine without a prescription, follow the instructions on the medicine label.
  • If you are using this medicine to treat heartburn, do not take it for more than 14 days or more often than every 4 months unless directed by your doctor.
