At times, a drug may have a different or enhanced effect when other diseases are present. At other times, the drug may worsen or effect another disease. Severe advanced liver and kidney disease may result in higher blood levels of the drug since these organs help to metabolize the drug. If you have an infection of the stomach caused by Helicobacter pylori bacteria, the drug by itself will reduce the number of bacteria in the stomach, but will not cure the infection. It is possible that the use of the drug long-term while this infection is present could seriously damage the stomach. There is a simple blood test available to see if you have ever been infected with this bacteria. Ask your physician.
The drug is used for almost any condition where stomach acid is causing a problem or tissue injury. These include peptic ulcers in the stomach and duodenum and gastroesophageal reflux disease where acid splashes back into the food pipe causing injury. An uncommon disease, called Zollinger-Ellison Syndrome, results in the production of huge amounts of stomach acid because of uncontrolled stimulation of the stomach by a hormone called gastrin. Severe ulcers can then occur. Omeprazole is also used along with antibiotics to cure or eradicate a stomach infection caused by Helicobacter pylori. These bacteria have been shown to cause peptic ulcers. Finally, some physicians will use the drug for simple hyperacidity although the FDA has not approved it for this purpose.

Adverse reactions can occur with any drug, even over-the-counter medications. Some of these are mild such as a stomach upset, which may be avoided by taking the medication with food. Minor reactions may go away on their own but if they persist, contact the physician. For major reactions, the patient should contact the physician immediay.
Certain other drugs require stomach acid to be changed into their active form to be absorbed. Since Omeprazole eliminates stomach acid so effectively, the absorption of the following drugs may be adversely affected:
Most females now know that, if possible, no drug, including alcohol, should be taken during pregnancy or lactation. The potential danger, of course, is an injury to the baby. However, some drugs are much safer than others in this regard. So, the FDA has a grading system for each drug which reflects what is known medically. It ranks drugs from A, where medical studies show no evidence for danger to the fetus or mother, to B, C, D and X, where the medical evidence indicates that the risk to the fetus outweighs any benefit to the mother. Omeprazole is ranked C. Always consult your physician before taking any drug during or when planning pregnancy.
Omeprazole and similar drugs have revolutionized the treatment of acid disorders. Patients often say “it’s like a miracle” and “I can eat anything now”. Not only can ulcer and acid pain be readily controlled, but the ulcer heals quickly, especially if aspirin or arthritis medications are not taken, or if the Helicobacter pylori bacteria infection is cured. A major and certainly welcomed finding is that the drug appears to be safe long-term. However, we still do not have complete data on its safety over the long-term. So patients should stay in touch with their physician.
There are no known interactions with omeprazole and food or beverages. However, nicotine, caffeine and alcohol can stimulate stomach acid or delay ulcer healing. In all honesty, this drug is so potent that many of the previous recommendations about dietary and other precautions with ulcer healing are no longer as important as they once were. Still, listen to your physician’s recommendations.
Interactions with this drug may occur with the following:
If you miss a dose in the morning but remember in the afternoon, take it for that day. Otherwise, continue the next day as before and don’t double up. The drug is most effective if taken right before eating.
An interaction generally means that one drug may increase or decrease the effect of another drug. Also, the more medications a person takes, the more likely there will be a drug interaction.
There are no known adverse effects of Omeprazole on sexual function.
People who have known allergies or asthma may be at an increased risk for a reaction from any new medication. The physician should always know a patient’s allergy history. Signs of an allergic reaction are hives or skin rash. Of course, a person should not take omeprazole if there has been a previous reaction to this or a similar drug called Lansoprazole (trade name, Prevacid).
This medicine belongs to a group of drugs called proton pump inhibitors (PPI). The proton pump is the site within the stomach cell where hydrochloric acid is actually made and pumped out into the stomach. The PPIs block the formation of acid in the stomach from 80% to over 90% if enough of the drug is taken.
For Omeprazole, the following are the observed side effects:

Follow your physician’s instructions carefully. Omeprazole is usually taken once or twice a day before a meal. The capsule should not be crushed or opened. Keep all medications away from children. Never share your medications with anyone else.
The FDA has no restrictions on length of use. Physicians from around the world have been prescribing it for well over 15 years and no serious long-term side effects have been described. It looks like it is a very safe drug even though some minor changes in the stomach cells can be seen when biopsies are reviewed under the microscope.
