Nexium (esomeprazole magnesium) is a proton pump inhibitor (PPI) prescribed for the management of gastroesophageal reflux disease (GERD), erosive esophagitis, and other conditions related to excess stomach acid. As a next-generation PPI, it offers targeted, long-lasting acid suppression by inhibiting the final step of gastric acid production. Clinically proven to provide sustained relief, it supports mucosal healing and improves quality of life for patients with chronic acid-related disorders. This medication is available in both prescription and over-the-counter strengths, tailored to individual therapeutic needs.
Features
- Contains esomeprazole magnesium, the S-isomer of omeprazole
- Delayed-release formulation for targeted intestinal absorption
- Available in multiple dosages: 20mg and 40mg capsules, packets for oral suspension, and intravenous injection
- 24-hour acid control with a single daily dose
- Acid-resistant enteric coating to protect the active ingredient from stomach degradation
Benefits
- Provides rapid and sustained relief from heartburn and acid regurgitation
- Promotes healing of erosive esophagitis with proven efficacy in clinical trials
- Reduces the risk of NSAID-associated gastric ulcers in at-risk patients
- Enables long-term maintenance therapy for GERD with a favorable safety profile
- Improves sleep and daily functioning by controlling nighttime acid breakthrough
- Supports combination therapy for Helicobacter pylori eradication
Common use
Nexium is commonly used for the short-term treatment (4 to 8 weeks) of erosive esophagitis, for maintaining healing of erosive esophagitis, and for managing symptomatic gastroesophageal reflux disease (GERD). It is also indicated for reducing the risk of gastric ulcers developing in patients on continuous NSAID therapy, and as part of combination therapy for H. pylori infection. Some patients use the over-the-counter version for frequent heartburn (occurring 2 or more days per week).
Dosage and direction
The recommended adult dosage for healing erosive esophagitis is 20mg or 40mg once daily for 4 to 8 weeks. For maintenance of healing of erosive esophagitis, the dose is 20mg once daily. For GERD symptoms, 20mg once daily for 4 weeks is typical. For H. pylori eradication, Nexium 40mg once daily is combined with amoxicillin and clarithromycin for 10 days. Nexium should be taken at least one hour before a meal, preferably in the morning. The capsule must be swallowed whole; it should not be crushed, chewed, or split. For patients with difficulty swallowing, capsules may be opened and mixed with applesauce, or the oral suspension formulation may be used.
Precautions
Patients should inform their healthcare provider of any liver disease, as dosage adjustment may be necessary. Long-term use (beyond one year) may lead to decreased magnesium levels, vitamin B12 deficiency, or increased risk of bone fractures. Nexium may mask symptoms of gastric malignancy; appropriate diagnostic evaluation should be conducted if alarm symptoms (e.g., unintentional weight loss, recurrent vomiting, dysphagia) occur. Use during pregnancy only if clearly needed. Not recommended during breastfeeding unless benefits outweigh risks.
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 reduced antiviral efficacy. Should not be used in patients taking drugs whose absorption is pH-dependent (e.g., certain antifungals, HIV protease inhibitors) without careful monitoring and dose adjustment.
Possible side effect
Common side effects include headache, diarrhea, nausea, flatulence, abdominal pain, constipation, and dry mouth. Less frequently, dizziness, rash, or cough may occur. Serious side effects, though rare, may include severe allergic reactions, acute interstitial nephritis, Clostridium difficile-associated diarrhea, cutaneous lupus erythematosus, and subacute cutaneous lupus erythematosus. Long-term use has been associated with hypomagnesemia, vitamin B12 deficiency, and increased risk of fractures.
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. It may increase systemic concentrations of drugs metabolized by CYP2C19, such as diazepam, citalopram, and imipramine. Concomitant use with clopidogrel may reduce the antiplatelet effect. St. John’s Wort or rifampin may decrease esomeprazole levels.
Missed dose
If a dose is missed, it should be taken as soon as remembered, unless it is nearly time for the next dose. In that case, skip the missed dose and resume the regular dosing schedule. Do not double the dose to make up for a missed one.
Overdose
Limited data exist on esomeprazole overdose. Symptoms may reflect those of side effects but amplified, such as gastrointestinal disturbances, confusion, drowsiness, blurred vision, tachycardia, and sweating. Management is supportive and symptomatic; dialysis is not likely to be effective due to high protein binding. In case of suspected overdose, contact a poison control center or seek emergency medical attention.
Storage
Store at room temperature (20–25°C or 68–77°F), in a dry place, away from light and moisture. Keep in the original container with the lid tightly closed. Do not store in bathrooms 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 patient reports consistently affirm the efficacy of Nexium in managing acid-related symptoms. In randomized controlled trials, up to 94% of patients with erosive esophagitis showed healing after 8 weeks of treatment. Many users report significant improvement in quality of life, reduced nighttime symptoms, and better tolerance of trigger foods. Some note the convenience of once-daily dosing. A minority of users report side effects such as headache or gastrointestinal discomfort, which often resolve with continued use. Long-term users are advised to periodically reassess therapy with their healthcare provider.
