How does this medication work? What will it do for me?
Omeprazole belongs to the family of medications called proton pump inhibitors (PPIs). It slows or prevents the production of acid within the stomach.
Omeprazole is used to treat conditions where reduction in acid secretion is required for proper healing, including stomach and intestinal ulcers (gastric and duodenal ulcers), the prevention and treatment of ulcers associated with medications known as NSAIDs, reflux esophagitis, Zollinger-Ellison syndrome, heartburn, and gastroesophageal reflux disease (GERD).
It is also used in combination with antibiotics to treat stomach ulcers caused by H. pylori bacteria.

How should I use this medication?
The usual recommended dose of omeprazole is 10 mg to 40 mg once daily. The dose and length of treatment depends on the condition being treated. This medication can be taken with or without food and should be swallowed whole with water.
When used to treat ulcers in the duodenum, the recommended adult dose is 20 mg taken once daily for 2 to 4 weeks.
To treat ulcers in the stomach, reflux esophagitis, and ulcers associated with the use of NSAIDs, the recommended adult dose is 20 mg taken once daily for 4 to 8 weeks.
For treatment of heartburn, the recommended adult dose is 20 mg daily.
When used to treat stomach ulcers caused by H. pylori in adults, the dose of omeprazole is 20 mg taken 2 times daily with 1,000 mg of amoxicillin 2 times daily and 500 mg of clarithromycin 2 times daily, all for 7 days. Another dosing regimen for H. pylori infections is 20 mg of omeprazole, 500 mg of metronidazole, and 250 mg of clarithromycin, all twice daily for 7 days.
If your ulcer continues to bother you, your doctor may suggest that you continue taking omeprazole for a period of time to make sure that your ulcer is fully healed.
When treating Zollinger-Ellison syndrome, the dose of omeprazole varies, but is often higher than the doses used to treat ulcers. Doses larger than 80 mg daily are often needed.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Diarrhea: When gastric acid is decreased, the number of bacteria normally in the digestive system increases. Occasionally, this can cause serious infection in the digestive tract. If you experience watery, foul-smelling bowel movements after starting to take omeprazole, contact your doctor as soon as possible.
Fluid and electrolyte balance: Omeprazole, like other PPIs, may cause the levels of electrolytes such as potassium, sodium, magnesium, chloride, and calcium in the blood to change while taking this medication. If you experience symptoms of fluid and electrolyte imbalance such as muscle pains or cramps; dry mouth; numb hands, feet, or lips; or racing heartbeat, contact your doctor as soon as possible. Your doctor will do blood tests regularly to monitor the levels of these electrolytes in your blood while you are taking this medication.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication. People with severe liver disease should generally not take more than 20 mg of omeprazole daily.
Methotrexate interaction: Omeprazole, like other medications in this group, may interact with methotrexate when the two medications are used at the same time. This combination may lead to higher than expected amounts of methotrexate in the body and can cause serious side effects, including kidney damage, irregular heartbeat, anemia, or infection. If you take omeprazole and are also going to receive a dose of methotrexate, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Osteoporosis-related fractures: Studies suggest that the use of omeprazole, like other PPIs, may be related to an increase risk of fractures, particularly for people who take this medication for a year or longer. The lowest dose of this medication to control the symptoms, taken for the shortest period of time is less likely to cause these problems.
Severe stomach problems: If you have recurrent vomiting, difficulty swallowing, blood in the stool, coughing up of blood, or significant unintentional weight loss, check with your doctor immediately. These symptoms may be signs of a more serious stomach problem.
Subacute cutaneous lupus erythematosus (SCLE): Omeprazole, like other PPIs, has been rarely associated with SCLE, an autoimmune disease. If you develop any skin lesions, especially in sun-exposed skin areas, and if accompanied by muscle aches or pains, contact your doctor immediately.
Vitamin B12: Long-term use of omeprazole may lead to vitamin B12 deficiency. If you are a vegetarian or have low vitamin B12 levels, discuss with your doctor whether any special monitoring is required.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, call your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking omeprazole, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take.
