Omeprazole (Prilosec®) for GERD and Ulcers

Omeprazole is a proton pump inhibitor that reduces stomach acid. It treats frequent heartburn, gastroesophageal reflux disease (GERD), ulcers, and other acid-related conditions. Omeprazole is the active ingredient in Prilosec®. CanadianInsulin supplies omeprazole from Canada and ships to the US, with US delivery from Canada and Canadian pricing for those paying without insurance.

Omeprazole reduces stomach acid by blocking the proton pumps that produce acid in the stomach lining. Lowering acid helps relieve heartburn and allows inflamed tissue to heal. It is used for GERD, erosive esophagitis, gastric and duodenal ulcers, Helicobacter pylori treatment in combination with antibiotics, and pathological hypersecretory conditions such as Zollinger-Ellison syndrome.

Many prescriptions are written for omeprazole delayed release 20 mg. You may see this labeled as an omeprazole DR 20 mg capsule, omeprazole 20mg capsules, omeprazole 20 mg tablets, or omeprazole delayed release tablets 20 mg. Some labels also describe the form as capsule, delayed-release (CPDR). Patients and caregivers often search for omeprazole online or for Prilosec 20 mg when comparing choices.

¿Para quién es el omeprazol?

Omeprazole is used in adults to treat frequent heartburn and GERD, to heal and maintain healing of erosive esophagitis, and to manage gastric or duodenal ulcers. It is also used with antibiotics to eradicate H. pylori in adults. Pediatric use for GERD is common in patients 1 to 16 years, as directed by a clinician.

Omeprazole should not be used in patients with known hypersensitivity to omeprazole or other substituted benzimidazoles. Avoid use with rilpivirine-containing products. People with alarm symptoms such as difficulty swallowing, vomiting blood, black stools, or unexplained weight loss need medical evaluation before acid suppression therapy.

If reflux symptoms relate to delayed gastric emptying, clinicians may consider a prokinetic such as Metoclopramida for select cases. To review more therapies for digestive conditions, explore our Trastornos gastrointestinales categoría.

Posología y utilización

Dosing and duration depend on the condition and patient factors. Follow your prescription and the official label.

• Frequent heartburn (OTC use): 20 mg once daily for 14 days. Do not exceed one 14‑day course every four months unless directed by a clinician.
• GERD and erosive esophagitis: often 20 mg once daily for 4 to 8 weeks; some patients continue 20 mg daily for maintenance as directed.
• Duodenal ulcer: commonly 20 mg once daily for 4 weeks; some cases need longer.
• H. pylori eradication: typical triple therapy uses omeprazole 20 mg twice daily with antibiotics such as amoxicillin and clarithromycin for 10 to 14 days.
• Zollinger‑Ellison syndrome: higher individualized doses, often starting near 60 mg daily, with titration by the prescriber.

Take omeprazole before a meal, usually in the morning. Swallow delayed-release capsules or tablets whole. Some capsule products may be opened and sprinkled on soft food, as described on the label. Do not crush or chew delayed-release forms.

When a prescriber specifies strength, it may appear as an omeprazole 20 mg prescription, sometimes written as 20mg omeprazole capsule or omeprazole DR 20 mg capsule.

Fortalezas y formas

• Delayed-release capsules: 10 mg, 20 mg, 40 mg.
• Delayed-release tablets: 20 mg. Many OTC products are listed as Prilosec OTC 20 mg or omeprazole magnesium 20 mg.
• Delayed-release powder for oral suspension packets: commonly 2.5 mg and 10 mg per packet for select pediatric or adult uses.

Availability can vary by manufacturer and country. Labels may describe forms as omeprazole delayed release 20 mg, omeprazole 20 mg tablets, or CPDR capsule. Product images and excipients may differ by brand.

Dosis omitida y momento oportuno

If a dose is missed, take it when remembered unless it is close to the next scheduled dose. Do not take two doses at the same time. For twice-daily therapy, keep doses spaced as evenly as possible. For OTC courses, take one dose daily for 14 days.

Almacenamiento y viaje

Store omeprazole at room temperature. Protect from moisture and keep the bottle tightly closed. Keep tablets and capsules in the original container or blister until use. Typical labels recommend controlled room temperature near 20 to 25°C (68 to 77°F), with brief excursions allowed.

When traveling, carry your medicine in its original labeled container. Keep it in your carry-on, away from heat and humidity. Use your refill reminders so you have enough supply for the full trip.

Beneficios

Omeprazole reduces gastric acid and helps heal inflamed tissue in the esophagus and stomach. For many conditions, once-daily dosing is convenient. Delayed-release formulations are designed to protect the medicine so it reaches its site of action beyond the stomach acid. Treatment can reduce heartburn frequency and improve quality of life when used as directed.

Efectos secundarios y seguridad

• Dolor de cabeza
• Náuseas o vómitos
• Diarrea o estreñimiento
• Dolor o hinchazón abdominal
• Gas and belching
• Mareos
• Cough or upper respiratory symptoms
• Erupción o picor

Serious effects are uncommon but can occur. These include severe allergic reactions; acute interstitial nephritis; Clostridioides difficile–associated diarrhea; low magnesium with muscle cramps or arrhythmias; vitamin B12 deficiency with long-term use; bone fracture risk with prolonged high-dose use; cutaneous or systemic lupus; fundic gland polyps; and severe skin reactions. Seek urgent care for melena, hematemesis, chest pain, severe abdominal pain, or persistent vomiting.

Interacciones medicamentosas y precauciones

• Clopidogrel: omeprazole can reduce activation and effect; avoid co-use unless directed.
• Rilpivirine and some HIV protease inhibitors: PPIs can reduce levels and are contraindicated or not recommended.
• Warfarin: monitor for changes in anticoagulation.
• Diazepam, phenytoin, and other CYP2C19 substrates: levels may increase; monitoring may be needed.
• Methotrexate (high-dose): temporary PPI interruption may be considered by the prescriber.
• Drugs needing acid for absorption, such as ketoconazole or itraconazole: effectiveness may decrease.
• Digoxin: absorption may increase; monitor as indicated.
• St. John’s wort or rifampin: may lower omeprazole levels.

People with severe liver impairment, osteoporosis risk, or low magnesium should use caution under medical supervision. Tell your clinician about all medicines, vitamins, and supplements.

Qué esperar con el tiempo

Heartburn relief may begin within the first few days, with maximum effect often seen after several days of daily use. Healing of erosive esophagitis and ulcers takes longer and should be guided by a clinician. Long-term therapy is sometimes needed for chronic GERD or hypersecretory conditions.

Comparar con alternativas

H2 blockers reduce acid by a different pathway and may suit milder or intermittent symptoms. A common option is Famotidina. Protective agents that coat ulcers and erosions can also help in selected cases, such as Sucralfato. Choice depends on diagnosis, symptom pattern, and medical history.

Disponibilidad y sustituciones

Adecuación al paciente y consejos para ahorrar costes

Omeprazole is suitable for many adults with acid-related conditions when used as directed. It is not for immediate relief of heartburn. People with alarm symptoms or complex histories need medical evaluation before therapy. During ulcer care, some patients use coating agents; a liquid option is Sulcrate® Suspensión Plus cuando se prescribe.

To save on total costs, ask about a multi-month supply when appropriate. Schedule refills before travel. Use reminders so you do not run out between visits.
