Version July 2025
Dosage guidance:
Dosing: All dosing is expressed in terms of esomeprazole base, regardless of the salt associated with the dosing information. Esomeprazole strontium 24.65 mg is equivalent to 20 mg of esomeprazole base; esomeprazole strontium 49.3 mg is equivalent to 40 mg of esomeprazole base.
Eosinophilic esophagitis (off-label use): Oral: 20 to 40 mg twice daily for an 8-week trial (Ref). Once 8-week trial is complete and remission is achieved, the dose may be gradually lowered to an individualized maintenance level (Ref). Some experts initiate with once-daily dosing and increase to twice-daily dosing after 4 weeks if symptoms fail to improve (Ref).
Gastroesophageal reflux disease, erosive or nonerosive:
Note: For patients with alarm symptoms (eg, dysphagia), referral to a specialist is recommended (Ref). For maximal efficacy, administer 30 to 60 minutes prior to a meal (Ref). Maximal acid suppression is generally observed after ~3 days of continuous therapy (Ref).
Initial therapy:
Mild/intermittent disease (<2 episodes/week) without erosive esophagitis or Barrett esophagus:
Note: Some experts reserve proton pump inhibitors (PPIs) as alternatives to H2-receptor antagonists (H2RAs) for patients who have residual acid reflux symptoms despite twice-daily H2RA (Ref).
Oral: 20 mg once daily for 4 to 8 weeks (Ref). Note: Some experts continue therapy until patient has been asymptomatic for 8 weeks (Ref).
Severe and/or frequent symptoms (≥2 episodes/week) without erosive esophagitis or Barrett esophagus:
Oral: 20 to 40 mg once daily for 4 to 8 weeks (Ref). Note: Some experts use 20 mg once daily and continue therapy until patient has been asymptomatic for 8 weeks (Ref).
Erosive esophagitis or Barrett esophagus:
Oral: 40 mg once daily for 4 to 8 weeks then 20 mg once daily indefinitely (Ref) or 20 mg once daily indefinitely (preferred by some experts) (Ref).
IV (alternative route): 20 or 40 mg once daily for ≤10 days. Note: For use in patients with erosive esophagitis when oral therapy is not appropriate. Safety and efficacy have not been established for use >10 days (Ref).
Residual symptoms despite 20 mg once daily:
Note: Referral to a specialist is recommended. Options include doubling the PPI dose, switching to a different PPI, or adding an H2RA (Ref). For patients requiring concomitant H2RA therapy, some experts administer the H2RA at bedtime (Ref); however, others advocate concurrent administration to ensure adherence (Ref).
Recurrent symptoms after discontinuing acid suppression:
Intermittent symptoms: Oral: 20 mg once daily as needed (Ref). Note: Some experts do not recommend intermittent use due to reduced efficacy (Ref).
Persistent symptoms (eg consistent with symptoms at diagnosis):
Recurrent symptoms after ≥3 months: Repeat an 8-week course at the previously effective dose (Ref).
Recurrent symptoms after <3 months: Long-term maintenance at the lowest effective dose necessary; referral to a specialist is recommended (Ref).
OTC labeling (patient-guided therapy): Heartburn, frequent symptoms (≥2 episodes/week): Oral: 20 mg once daily for 14 days (maximum: 20 mg/day); may repeat 14-day course every 4 months if needed. Seek medical referral if symptoms do not resolve within 14 days of treatment; do not take for >14 days or more often than every 4 months unless directed by a physician (Ref).
Helicobacter pylori eradication: Oral: 20 to 40 mg twice daily for 14 days as part of an appropriate combination regimen with antibiotics. Dose depends on the selected regimen (Ref).
NSAID-induced gastric ulcers, prevention: Oral: Esomeprazole magnesium, esomeprazole strontium: 20 to 40 mg once daily for up to 6 months; Note: 40 mg daily did not show additional benefit over 20 mg daily in clinical trials. Esomeprazole strontium capsules have been discontinued in the United States for >1 year.
Pathological hypersecretory conditions (Zollinger-Ellison syndrome):
Oral: Esomeprazole magnesium, esomeprazole strontium: 40 mg twice daily; adjust regimen to individual patient needs; doses up to 240 mg daily have been administered. Note: Esomeprazole strontium capsules have been discontinued in the United States for >1 year.
Stress ulcer prophylaxis in critically ill patients (off-label use):
Oral, IV: 40 mg once daily; discontinue prophylaxis once risk factors have resolved (Ref).
Upper GI bleed, acute:
Pre-endoscopy (unknown etiology) (off label): Note: Optimal proton pump inhibitor (PPI) therapy is uncertain. For patients with suspected active upper GI bleed, some experts suggest initiating high-dose IV PPI with continuous or intermittent dosing prior to endoscopy (Ref). Where IV PPIs are unavailable, high-dose oral PPI therapy is a reasonable alternative (Ref).
Continuous infusion: IV: 80 mg bolus, followed by 8 mg/hour until endoscopy with subsequent dosing based on endoscopic findings (Ref).
Intermittent dosing: IV: 80 mg once (active bleeding) or 40 mg once (no evidence of active bleeding); if endoscopy is not performed within 12 hours, begin 40 mg every 12 hours until endoscopy. Subsequent dosing is based on endoscopic findings (Ref).
Oral (alternative route): 40 mg twice daily (Ref). Note: For select patients at low risk for rebleeding (ie, GBS of 0 to 1, clinically stable, timely access to medical care) who are to receive outpatient endoscopy, some experts use 20 mg once daily (Ref).
Postendoscopy (peptic ulcer hemorrhage): Note: Treatment should address the underlying cause of the bleed. In patients with bleeding peptic ulcers, continue PPI therapy and direct further treatment at healing the ulcers and eliminating precipitating factors (eg, H. pylori, nonsteroidal anti-inflammatory drugs) (Ref).
Peptic ulcer with high-risk stigmata of recent hemorrhage (eg, active bleed, visible vessel, adherent clot):
Continuous infusion: IV: 80 mg bolus, followed by 8 mg/hour; if patient received 80 mg bolus prior to endoscopy, may omit bolus dose. Continue for ≥72 hours, then transition to high-dose oral maintenance therapy when able to tolerate (Ref).
Intermittent dosing (alternative administration): IV: 80 mg bolus once, then 40 mg every 12 hours; if 80 mg bolus was received prior to endoscopy, may omit bolus dose. Continue for ≥72 hours, then transition to high-dose oral maintenance therapy when able to tolerate (Ref).
Maintenance therapy: Oral: 40 mg twice daily for 14 days, followed by 40 mg once daily (Ref).
Duration: The total duration of treatment depends on size, location, and cause of the ulcer and ranges from 4 to 12 weeks (Ref).
Peptic ulcer with clean base or flat pigmented spot: Note: May transition to an oral PPI immediately after endoscopy (Ref).
Maintenance therapy: Oral: 20 mg once daily (Ref).
Duration: The total duration of treatment depends on size, location, and cause of the ulcer and ranges from 4 to 12 weeks (Ref).
Discontinuation of therapy: Oral: Some experts recommend a step-down approach in order to avoid worsening or rebound symptoms. One recommendation is to decrease the dose by 50% over 2 weeks to 4 weeks. If the patient is already on the lowest possible dose, alternate-day therapy may be considered. If symptoms worsen during treatment or after discontinuation, patient should be re-evaluated (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

25 to 34 kg: 30 mg twice daily.
>34 kg: 40 mg twice daily.
Discontinuation of therapy: Oral: Based on experience in adults, some experts recommend a step-down approach in order to avoid worsening or rebound symptoms. One recommendation is to decrease the dose by 50% over 2 to 4 weeks. If the patient is already on the lowest possible dose, alternate day therapy may be considered. If symptoms worsen during treatment or after discontinuation, patient should be reevaluated (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Infants, Children, and Adolescents: Oral, IV: No dosage adjustments necessary.
There are no specific pediatric recommendations; based on experience in adult patients, adjustment suggested in severe impairment.
Cutaneous lupus erythematosus, most often subacute cutaneous lupus erythematosus (SCLE), has been reported with use of proton pump inhibitors (PPIs), including esomeprazole (Ref). SCLE is reversible (resolution ~3 months following discontinuation [range: 4 weeks to 8 months]), and cross-reactivity between PPIs has been reported (Ref). SCLE may present as a widespread skin rash which may include bullous lesions and focal skin necrosis (Ref). In addition, systemic lupus erythematosus secondary to PPIs may occur, although less often as compared to SCLE. Presentation often includes rash; however, arthralgia or cytopenia may also occur.
Mechanism: Non–dose-related; immunologic. SCLE is typically associated with positive antinuclear antibodies, anti-Ro/SSA, and anti-La/SSB antibodies (Ref).
Onset: Varied.
Cutaneous lupus erythematosus: Approximately 8 months following treatment initiation (range: 3 days to 3.5 years) (Ref).
Systemic lupus erythematosus: According to the manufacturer, may occur within days to years after initiating treatment.
Risk factors:
• Prior history or family history of SCLE, especially secondary to PPIs (Ref)
• Presence of risk factors for SCLE (eg, female of childbearing age, periods of female hormone changes, prior history of drug allergies, sun-reactive skin, exposure to UV radiation) (Ref)
Use of proton pump inhibitors (PPIs), including esomeprazole, may increase risk of enteric infections in adult and pediatric patients, including gastroenteritis and Clostridioides difficile-associated diarrhea (CDAD); however, data are conflicting, especially with regard to CDAD (Ref). Diarrhea, which may be a result of enteric infection, is the most common adverse effect secondary to long-term PPI use and often results in treatment discontinuation (Ref). Consider CDAD diagnosis in patients with persistent diarrhea that does not improve, especially in hospitalized patients.
Mechanism: Dose-related (Ref); related to the pharmacologic action. The increase in gastric pH secondary to PPI administration leads to changes in intestinal microbial environment which may allow for intestinal germination and growth of C. difficile spores, as well as colonization by other bacteria responsible for enteric infections (eg, Salmonella, Campylobacter, Shigella, norovirus) and multidrug-resistant microorganisms (Ref).
Onset: Varied; hospitalized patients receiving high doses may experience CDAD within days of treatment initiation (Ref), whereas others develop gastroenteritis with long-term therapy in the community setting (Ref).
Risk factors:
• High doses of PPIs (eg, daily or more frequently than daily use) (Ref)
• Hospitalized patients (Ref)
• Infants and children with defective immune systems or indwelling catheters (Ref)
Use of proton pump inhibitors (PPIs), including esomeprazole, may increase the risk of bone fracture in children, young adults, and older adults, including osteoporosis-related fractures (Ref). However, data regarding the impact of PPIs on fractures, as well as bone mineral density (BMD), are inconclusive and some have concluded that any association with fracture may be related to other independent risk factors (Ref).
Mechanism: Dose-related; related to the pharmacologic action (hypergastrinemia and hypochlorhydria). Hypergastrinemia causes secondary hyperparathyroidism which can increase bone resorption and subsequent decreased BMD. Hypochlorhydria results in decreased absorption of calcium, magnesium, and vitamin B12. Impaired calcium absorption may cause secondary hyperparathyroidism and decreased BMD. Decreased vitamin B12 absorption may decrease osteoblastic activity leading to decreased BMD, as well as decreased collagen cross-linking leading to weakened bone structure (Ref).
Onset: Delayed (≥1 year) (Ref).
Risk factors:
• Presence of risk factors for fractures and/or osteoporosis (Ref)
• Duration of therapy (eg, ≥1 year) (Ref)
• High doses of PPIs (≥1.5 doses per day) (Ref)
• Pediatric: Initiation of therapy at age <1 year or ≥6 years (Ref)
• Pediatric: Concurrent use of PPI plus H2 blocker (Ref)
Long-term use of proton pump inhibitors (PPIs), including esomeprazole, has been associated with the development of reversible gastric polyp (fundic gland) (Ref). Most PPI users who developed fundic gland polyps were asymptomatic. Symptomatic patients may report nausea, vomiting, or abdominal pain. GI bleeding and/or anemia may occur with ulcerated polyp. Clinicians should note that Helicobacter pylori infection may be protective against fundic gland polyps as bacterial proteases help glandular outflow by breaking down blockages (Ref).
Mechanism: Time-related; long-term use of PPIs is associated with an increase in the prevalence of parietal cell protrusions which cause outflow blockage of the isthmus and subsequent formation of fundic gland cysts. As therapy continues, fundic gland cysts may enlarge and develop into fundic gland polyps (Ref).
Onset: Delayed (>1 year) (Ref).
Risk factors:
• Patients with familial adenomatous polyposis (Ref)
• Duration of treatment (>1 year and especially ≥5 years) (Ref)
Immediate hypersensitivity reactions secondary to proton pump inhibitors (PPIs) are rare and range from urticaria and angioedema to anaphylaxis (Ref). Delayed hypersensitivity reactions include maculopapular rash (Ref), as well as rare severe cutaneous adverse reactions (SCARs), such as acute generalized exanthematous pustulosis (Ref), drug reaction with eosinophilia and systemic symptoms, fixed drug eruption, Stevens-Johnson syndrome, and toxic epidermal necrolysis (Ref).
Mechanism: Non–dose-related; immunologic.
Immediate hypersensitivity reactions (eg, anaphylaxis, urticaria): IgE-mediated (Ref)
Delayed hypersensitivity reactions (including maculopapular rash and SCARs): T-cell-mediated (Ref).
Onset:
Immediate hypersensitivity reactions: Rapid; occurs within 1 hour of administration but may occur up to 6 hours after exposure (Ref).
Delayed hypersensitivity reactions:
Maculopapular reactions: Intermediate; generally occurs 7 to 10 days after initiation, but may occur up to 1 month following initiation of therapy (Ref).
Other reactions (including SCARs): Varied; occurs after 7 to 14 days up to 3 months following initiation of therapy (Ref).
Risk factors:
• Prior history of hypersensitivity reaction to PPIs (Ref)
• Cross-reactivity has been noted with PPIs, although cross-reactivity patterns have been variable (Ref)
Long-term use of proton pump inhibitors (PPIs), including esomeprazole, has resulted in reversible hypomagnesemia (Ref); rate of occurrence may be highest with omeprazole as compared to other PPIs (Ref). Symptoms may be severe (eg, tetany, cardiac arrhythmias, cerebellar syndrome, seizures) and resistant to treatment with supplementation (Ref). May require discontinuation of PPI in addition to magnesium supplementation in ~25% of patients. Following discontinuation, magnesium normalizes after ~1 week (Ref). Hypomagnesemia may recur if PPI therapy is restarted (Ref).
Mechanism: Time-related; the specific mechanism is unknown; however, long-term use of PPIs may be associated with changes in intestinal absorption of magnesium (Ref).
Onset: Delayed; hypomagnesemia occurs most often after 1 year of therapy but may occur as early as 3 months (Ref). In patients with prior PPI-induced hypomagnesemia, re-initiation may result in recurrence within 2 weeks (Ref).
Risk factors:
• Duration of therapy (≥3 months and especially >1 year) (Ref)
• Concurrent use of other drugs that cause hypomagnesemia (eg, loop diuretics, thiazide diuretics) (Ref)
• Patients who have undergone kidney transplantation (Ref)
Acute interstitial nephritis (AIN) may occur rarely with use of proton pump inhibitors (PPIs), including esomeprazole (Ref), with renal biopsy showing diffuse interstitial infiltrate and tubulitis (Ref). Patients generally achieve complete or partial recovery by 6 months following treatment of AIN (Ref). Signs of systemic hypersensitivity (fever, rash, eosinophilia) often seen in other cases of drug-induced AIN are not typically observed in proton pump inhibitor (PPI)-induced AIN (Ref). Clinicians should note that there appears to be no correlation between duration of exposure to PPI and duration or severity of acute kidney failure after resolution of AIN (Ref).
Mechanism: Non–dose-related; unknown although may be immunologic (Ref) or idiosyncratic, with direct toxic effect on tubular cells demonstrated with omeprazole (Ref).
Onset: Varied; usually occurs within 3 months (Ref) although has been reported to occur up to 10 months with other PPIs (Ref). Upon reexposure symptoms often present more rapidly, often within 12 hours (Ref).
Risk factors:
• Older adults; although this may be due to increased use of PPIs (Ref)
• Cross-reactions among PPIs in patients who developed AIN is not known
• Concomitant use of a PPI may increase the risk of immune checkpoint inhibitor-induced nephritis (Ref)
Long-term use of acid suppressive therapies, including esomeprazole, may result in reversible vitamin B12 deficiency; however, data regarding the clinical significance of these changes and causality are conflicted (Ref).
Mechanism: Dose- and time-related; acid suppressive therapies interfere with acid-activated proteolytic digestion of dietary protein-bound vitamin B12 in the stomach, thereby resulting in malabsorption of vitamin B12 (Ref).
Onset: Delayed (Ref).
Risk factors:
• Duration of therapy (≥2 to 3 years); the association between ≥2 years of proton pump inhibitor (PPI) use and vitamin B12 deficiency was stronger among people <30 years of age and in females (Ref)
• High doses of PPIs (≥1.5 pills per day) (Ref)
• Presence of risk factors for vitamin B12 deficiency (eg, malnourished patients, vegan diet) (Ref)

Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
OTC labeling: When used for self-medication (OTC), do not use if you have trouble or pain when swallowing food; vomiting with blood, or bloody or black stools; heartburn with light-headedness, dizziness, or sweating; chest pain or shoulder pain with shortness of breath, sweating, pain spreading to arms, neck or shoulders, or light-headedness; frequent chest pain.
Disease-related concerns:
• Gastric malignancy: Relief of symptoms does not preclude the presence of a gastric malignancy.
• Hepatic impairment: Patients with severe hepatic impairment may require dosage reductions.
• Renal impairment: Pharmacokinetics of esomeprazole are not expected to be altered in renal impairment; dosage adjustments are not necessary for any degree of renal impairment when using esomeprazole magnesium or esomeprazole sodium. However, since clearance of strontium is reduced in mild to moderate renal impairment, esomeprazole strontium is not recommended for use in severe impairment (has not been studied).
Concurrent drug therapy issues:
• Clopidogrel: Proton pump inhibitors (PPIs) may diminish the therapeutic effect of clopidogrel, thought to be due to reduced formation of the active metabolite of clopidogrel. The manufacturer of clopidogrel recommends either avoidance of both omeprazole (even when scheduled 12 hours apart) and esomeprazole or use of a PPI with comparatively less effect on the active metabolite of clopidogrel (eg, pantoprazole). In contrast to these warnings, others have recommended the continued use of PPIs, regardless of the degree of inhibition, in patients with a history of GI bleeding or multiple risk factors for GI bleeding who are also receiving clopidogrel since no evidence has established clinically meaningful differences in outcome; however, a clinically significant interaction cannot be excluded in those who are poor metabolizers of clopidogrel (Abraham 2010; Levine 2011).
Special populations:
• Older adult: Bioavailability may be increased in older adult patients.
• Pediatric: Esomeprazole strontium: Strontium competes with calcium for intestinal absorption and is incorporated into bone; use of esomeprazole strontium in pediatric patients is not recommended.
Dosage form specific issues:
• Intravenous: Safety and efficacy of IV treatment for GERD beyond 10 days have not been established; transition from IV to oral therapy as soon possible.
Other warnings/precautions:
• Laboratory test interference: Serum chromogranin A (CgA) levels increase secondary to drug-induced decreases in gastric acid; may cause false-positive results in diagnostic investigations for neuroendocrine tumors. Temporarily stop esomeprazole treatment ≥14 days before CgA test; if CgA level high, repeat test to confirm. Use same commercial laboratory for testing to prevent variable results.

Oral capsule:
Gastric (eg, NG, G-tube ) or post-pyloric (eg, J-tube) tubes (≥8 French): To optimize effectiveness, esomeprazole should be separated from enteral nutrition (EN) (Ref). Remove plunger from the barrel of a 60 mL enteral dosing syringe. Open capsule and place intact granules into syringe; add 50 mL purified water to the syringe. Replace plunger and shake vigorously for 15 seconds. Do not administer if granules dissolve or disintegrate. Administer immediately via feeding tube (Ref).
General guidance: Hold EN 30 to 60 minutes prior to esomeprazole administration (Ref). Flush feeding tube with an appropriate volume of purified water (eg, 15 mL) before administration (Ref). Following administration, rinse container used for preparation with purified water; draw up rinse and administer contents to ensure delivery of entire dose (Ref). Flush feeding tube with an appropriate volume of purified water (eg, 15 mL) and restart EN (Ref).
Oral granules for suspension:
Gastric (eg, NG, G-tube) or post-pyloric (eg, J-tube) tubes (≥6 French): To optimize effectiveness, esomeprazole should be separated from EN (Ref). If using a 2.5 or 5 mg packet, add 5 mL purified water to an enteral dosing syringe, then remove plunger from the syringe, add granules from packet, and replace plunger. If using a 10, 20, or 40 mg packet, add at least 15 mL purified water to an enteral dosing syringe, then remove plunger from the syringe, add granules from packet, and replace plunger. Shake the syringe, leave 2 to 3 minutes to thicken. Shake the syringe again and administer, then refill the syringe with an equal amount of purified water as previously used (eg, 5 mL for a 2.5 or 5 mg packet; 15 mL for a 10, 20, or 40 mg packet), shake syringe and flush enteral feeding tube. Administer suspension within 30 minutes of preparation (Ref).

Prolonged treatment (≥2 years) may lead to malabsorption of dietary vitamin B12 and subsequent vitamin B12 deficiency (Lam, 2013).
Esomeprazole crosses the placenta (Saito 2020).
Following a maternal dose of esomeprazole 10 mg/day throughout pregnancy, cord blood concentrations at delivery were ~40% of those in the maternal serum (~12 hours after the last maternal dose). Twelve hours after delivery (~23 hours after the last maternal dose), esomeprazole was no longer detected in the infant serum (Saito 2020).
Outcome data following use of proton pump inhibitors (PPIs) during pregnancy are available (Choi 2023; Hussain 2022; Peron 2023).
Due to pregnancy-induced physiologic changes, some pharmacokinetic properties of esomeprazole may be altered. Data from a single dose study of esomeprazole in patients with preterm preeclampsia suggest clearance may be decreased, possibly due to inhibition of CYP2C19 (Gebreyesus 2022).
Recommendations for the treatment of gastroesophageal reflux disease in pregnant patients are available. When initiating treatment during pregnancy, a step-up approach, starting with diet and lifestyle modifications, is recommended. PPIs are considered acceptable for use during pregnancy when other medications are not effective (Ali 2022; Dunbar 2022; Thélin 2020).
Esomeprazole is present in breast milk (Saito 2020).
A case report describes maternal use of esomeprazole 10 mg/day throughout pregnancy and postpartum. Breast milk was sampled multiple times between 2 and 4 days after delivery at term. The highest breast milk concentration was 4 hours after the maternal dose (19.6 ng/mL) and esomeprazole was no longer detected in breast milk 10 hours after the maternal dose. Using the highest breast milk concentration, authors of the study determined the estimated daily infant dose via breast milk to be 0.003 mg/kg/day. This infant received >50% of nutrition via breast milk and was developing normally as of 6 months of age (Saito 2020).
According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and the benefits of treatment to the mother.
Take at least 1 hour before meals; best if taken before breakfast.
Susceptibility testing recommended in patients who fail H. pylori eradication regimen. Monitor for rebleeding in patients with upper GI bleeding or peptic ulcer bleed.
