GENERIC NAME(S): Omeprazole, Omeprazole Magnesium
Omeprazole is used to treat certain stomach and esophagus problems (such as acid reflux, ulcers). It works by decreasing the amount of acid your stomach makes. It relieves symptoms such as heartburn, difficulty swallowing, and persistent cough. This medication helps heal acid damage to the stomach and esophagus, helps prevent ulcers, and may help prevent cancer of the esophagus. Omeprazole belongs to a class of drugs known as proton pump inhibitors (PPIs).
How to use Prilosec
Take this medication by mouth as directed by your doctor, usually once daily before a meal. This medication may also be given through a tube into the stomach (nasogastric or gastric tube). Dosage and length of treatment are based on your medical condition and response to treatment. In children, the dosage is also based on weight.
If you are taking this medication by mouth, empty the contents of a packet into a container with 1 to 3 teaspoons (5 to 15 milliliters) of water. Check the manufacturer package directions for the proper amount of water to use for your dose. Stir the mixture well and leave it for 2 to 3 minutes to thicken. Stir again and drink all of the mixture within 30 minutes. If any medication remains in the container, add more water, stir, and drink right away to make sure you take the entire dose. Do not crush or chew the medication granules. Doing so may destroy the drug.
If you are giving this medication through a nasogastric or gastric tube, ask your health care professional for detailed instructions on how to properly mix and give it.
If needed, antacids may be taken along with this medication. If you are also taking sucralfate, take omeprazole at least 30 minutes before sucralfate.
Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Continue to take this medication for the prescribed length of treatment even if you are feeling better.
Tell your doctor if your condition persists or worsens. The risk of side effects goes up over time. Ask your doctor how long you should take this medication.
