Nexium (esomeprazole magnesium) is a proton pump inhibitor (PPI) designed for the effective, long-term management of gastroesophageal reflux disease (GERD) and related acid-mediated conditions. As a next-generation therapeutic agent, it offers superior acid suppression by targeting the proton pumps in the gastric parietal cells, thereby elevating the gastric pH and facilitating mucosal healing. Clinically validated through extensive research, it is indicated for both acute treatment and maintenance therapy in adults and pediatric patients. This product card provides a comprehensive, evidence-based overview intended for healthcare professionals and informed patients.

Common use

Nexium is commonly prescribed for the treatment of symptomatic gastroesophageal reflux disease (GERD), including heartburn and regurgitation. It is also indicated for the healing of erosive esophagitis, maintenance of healed esophagitis, and reduction in the risk of nonsteroidal anti-inflammatory drug (NSAID)-associated gastric ulcers. In combination with antibiotics, it is used for the eradication of Helicobacter pylori to reduce the risk of duodenal ulcer recurrence. Off-label uses may include other hypersecretory conditions, though such use should be guided by clinical evidence and specialist consultation.

Dosage and direction

The recommended adult dosage for healing erosive esophagitis is 40 mg once daily for 4 to 8 weeks. For maintenance of healing of erosive esophagitis, the dose is 20 mg once daily. Symptomatic GERD without esophagitis is treated with 20 mg daily for 4 weeks. For risk reduction of NSAID-associated gastric ulcers, the dose is 20 mg or 40 mg once daily. For H. pylori eradication, Nexium 40 mg once daily is given with amoxicillin 1000 mg and clarithromycin 500 mg, all twice daily for 10 to 14 days. Administer at least one hour before a meal, preferably in the morning. Do not crush or chew capsules; for those with difficulty swallowing, capsules may be opened and mixed with applesauce, or the oral suspension formulation may be used.

Precautions

Long-term use (beyond one year) of PPIs like Nexium may be associated with an increased risk of fractures of the hip, wrist, or spine, particularly in older adults or those on high-dose, long-term therapy. Hypomagnesemia has been reported rarely with prolonged treatment; monitor magnesium levels before initiation and periodically during long-term therapy. Avoid use in patients with suspected or known osteoporosis; consider calcium and vitamin D supplementation if long-term therapy is necessary. PPI therapy may increase the risk of Clostridium difficile-associated diarrhea; evaluate patients with persistent diarrhea. Avoid abrupt discontinuation, as rebound acid hypersecretion may occur; consider tapering the dose.

Contraindications

Nexium is contraindicated in patients with known hypersensitivity to esomeprazole, substituted benzimidazoles, or any component of the formulation. Concomitant use with rilpivirine-containing products is contraindicated due to the potential for decreased rilpivirine absorption and reduced efficacy. Do not use in patients taking drugs whose absorption is pH-dependent and for whom a reduction in gastric acid may lead to reduced bioavailability and loss of efficacy, such as certain azole antifungals or iron salts, without careful monitoring and dose adjustment.

Possible side effect

Common side effects (≥1%) include headache, diarrhea, nausea, flatulence, abdominal pain, constipation, and dry mouth. Serious but less common adverse reactions may include acute interstitial nephritis, cutaneous lupus erythematosus, systemic lupus erythematosus, vitamin B12 deficiency (with long-term use), hypomagnesemia, and fundic gland polyps. Clostridium difficile-associated diarrhea and bone fracture have been reported in observational studies. Patients should be advised to report any persistent or severe symptoms, including signs of kidney dysfunction (e.g., changes in urination) or allergic reactions.

Drug interaction

Nexium may alter the absorption of drugs that require gastric acid for bioavailability, such as ketoconazole, iron salts, erlotinib, dabigatran, and mycophenolate mofetil. Concurrent use with clopidogrel may reduce the antiplatelet activity of clopidogrel; avoid concomitant use unless absolutely necessary. Esomeprazole is metabolized by CYP2C19 and CYP3A4; drugs that inhibit or induce these enzymes may alter esomeprazole concentrations. Conversely, esomeprazole may inhibit CYP2C19, potentially increasing levels of drugs such as diazepam, citalopram, and phenytoin.

Missed dose

If a dose of Nexium is missed, it should be taken as soon as remembered, unless it is nearly time for the next scheduled dose. In that case, skip the missed dose and resume the usual dosing schedule. Do not double the dose to make up for a missed one. Consistency in dosing is important for maintaining acid control, but occasional missed doses are unlikely to significantly impact long-term efficacy.

Overdose

Limited data exist on esomeprazole overdose in humans. Experimental doses up to 280 mg daily have been administered without reported serious adverse effects. Symptoms of overdose may reflect those of side effects, such as gastrointestinal discomfort, drowsiness, blurred vision, tachycardia, and sweating. There is no specific antidote; treatment should be symptomatic and supportive. Hemodialysis is not expected to be effective due to high protein binding. In case of suspected overdose, contact a poison control center or seek medical attention.

Storage

Store Nexium capsules at room temperature, between 20°C to 25°C (68°F to 77°F), in a dry place away from light and moisture. Keep in the original container with the lid tightly closed to protect from moisture. Do not store in the bathroom or near sinks. Keep out of reach of children and pets. Do not use beyond the expiration date printed on the packaging.

Reviews

Clinical studies and meta-analyses consistently demonstrate the efficacy of Nexium in healing erosive esophagitis and providing symptom relief in GERD patients. In a 2019 systematic review, esomeprazole showed superior acid control compared to other PPIs in many head-to-head trials. Patient-reported outcomes often highlight significant improvement in quality of life, though some note the need for long-term management and occasional side effects such as headache or gastrointestinal discomfort. Always consult with a healthcare professional to evaluate whether Nexium is appropriate for your specific condition.
