Indications
- Omeprazole is utilized to address specific stomach and esophagus issues, including acid reflux and ulcers.
- The mechanism involves reducing stomach acid production.
- It alleviates symptoms like heartburn, difficulty swallowing, and cough.
- The medication aids in the healing of acid-induced damage to the stomach and esophagus.
- It also assists in preventing ulcers and may have a role in preventing esophageal cancer.
- Omeprazole belongs to a class of drugs called proton pump inhibitors (PPIs).
Dosage and administration
- Read the Medication Guide provided by your pharmacist before starting omeprazole and with each refill; consult your doctor or pharmacist if you have questions.
- Take this medication orally before a meal as directed by your doctor, usually once daily. Dosage and treatment duration depend on your medical condition and response. In children, dosage is weight dependent.
- If taking orally, empty the packet into a container with 1 to 3 teaspoons (5 to 15 milliliters) of water, following package directions. Stir well, let it thicken for 2 to 3 minutes, stir again, and consume the mixture within 30 minutes. If any medication remains, add more water, stir, and drink immediately. Do not crush or chew the granules.
- If administering through a tube, consult your healthcare professional for proper mixing and administration instructions.
- If necessary, antacids may be taken alongside omeprazole. If also taking sucralfate, take omeprazole at least 30 minutes before sucralfate.
- Use regularly at the same time each day for maximum benefit. Continue treatment for the prescribed duration, even if symptoms improve.
- Inform your doctor if your condition persists or worsens. The risk of side effects increases over time. Ask your doctor about the recommended duration of treatment.
Side effects
- Possible side effects of omeprazole include headache or abdominal pain; inform your doctor or pharmacist if these persist or worsen.
- This medication is prescribed because the benefits are considered greater than the risk of side effects; many users do not experience serious side effects.
- Notify your doctor immediately if you have serious side effects such as symptoms of low magnesium levels or signs of lupus.
- Omeprazole may rarely cause a severe intestinal condition due to C. difficile bacteria; contact your doctor if you develop persistent diarrhea, abdominal pain/cramping, or blood/mucus in your stool.
- Avoid using anti-diarrhea or opioid products if you experience these symptoms, as they may worsen the condition.
- Proton pump inhibitors like omeprazole may rarely lead to vitamin B-12 deficiency, especially with long-term daily use (3 years or longer); inform your doctor if you develop symptoms of B-12 deficiency.
- A very serious allergic reaction is rare but seek medical help if you notice symptoms like fever, swollen lymph nodes, rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing, or signs of kidney problems.
- This list may not include all possible side effects; contact your doctor or pharmacist for any unlisted effects.
Precautions
