Esomeprazole Patient Tips
Medically reviewed by C. Fookes, BPharm. Last updated on Dec 13, 2017.
How it works
- Esomeprazole reduces the production of stomach acid by irreversibly blocking the actions of an enzyme responsible for acid production, called H+/K+ ATPase (also known as the gastric proton pump). The proton pump is located in the parietal cells of the stomach wall. Both baseline gastric acid secretion and stimulated gastric acid secretion are affected.
- Esomeprazole allows damaged tissue in the esophagus, stomach, and duodenum to heal.
- Esomeprazole belongs to the class of medicines known as proton pump inhibitors (PPIs).
- Effective at healing erosive esophagitis (a severe inflammation of the lining of the esophagus- the tube that carries food from the mouth to the stomach), and relieving symptoms of gastro-esophageal reflux disease (also known as heartburn).
- May be taken at the same time as NSAIDs to reduce the risk of NSAID-associated gastric ulcers in those people on continuous NSAID therapy.
- May be used in conjunction with amoxicillin and clarithromycin in people with Helicobacter pylori infection and duodenal ulcer disease
- Useful in the treatment of hypersecretory conditions such as Zollinger-Ellison syndrome.
- The dosage of esomeprazole does not need adjusting in people with kidney disease.
- Generic esomeprazole is available.
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
- A headache, diarrhea or constipation, flatulence, nausea, abdominal pain, dry mouth or drowsiness are the most commonly reported side effects.
- May also interfere with some laboratory tests.
- PPIs (including esomeprazole) have been associated with an increased risk of osteoporosis-related fractures of the hip, wrist, or spine. People on high-dose or long-term therapy are more at risk.
- Has also been associated with other conditions such as lupus erythematosus and magnesium deficiency.
- Prolonged treatment (greater than 24-36 months) may cause vitamin B12 deficiency. The risk is greater in women, people aged less than 30, and with higher dosages.
- A dosage of 20mg esomeprazole should not be exceeded in people with severe liver disease.
- Administration of PPIs (such as esomeprazole), has been associated with acute interstitial nephritis, a severe inflammation of the kidneys. May occur on medication initiation or at any point of therapy. Symptoms include fever, rash and generalized aches and pains. Discontinue esomeprazole and seek medical advice.
- Has been associated with a greater risk of Clostridium difficile-associated diarrhea. See your doctor if you develop diarrhea that does not improve.
- Esomeprazole should not be given with clopidogrel because it can reduce the activity of clopidogrel. Esomeprazole may also interact with several other medications particularly those that induce the CYP2C19 or CYP3A4 hepatic enzymes such as St. John's Wort or rifampin. Esomeprazole can also reduce the absorption of drugs that are dependant on a certain gastric pH for their absorption.
- Usually, only up to 8 weeks of treatment is recommended. Controlled studies have not investigated use beyond 6 months; however, esomeprazole has been used long-term for the treatment of hypersecretory conditions such as Zollinger-Ellison syndrome.
Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

- Usually taken once daily.
- Take at least an hour before a meal.
- Swallow delayed-release capsules whole. In people who have difficulty swallowing, the capsule may be opened and the contents mixed with applesauce and swallowed immediately.
- See your doctor if you develop any unexplained fever, rash (particularly one that gets worse after you have been in the sun), new or worsening joint pain, persistent diarrhea or generalized aches and pains.
- Also see your doctor if you develop any muscle cramps, spasms, or weakness; jitteriness; abnormal heartbeat; dizziness; seizures; or any other symptoms of concern.
Response and Effectiveness
- Peak effects happen within one and a half hours and effects can last for over 24 hours.
- Esomeprazole delayed-release capsules and esomeprazole for delayed-release oral suspension are bioequivalent (the same dosage has the same effect in the body).
- The effect of esomeprazole depends upon the dosage given (more acid is suppressed with 40mg capsules than 20mg capsules); however, dosages above 40mg do not provide any more effect.
