Key safety warnings

Alarm symptoms such as significant unintentional weight loss, recurrent vomiting, dysphagia, haematemesis or melaena warrant exclusion of malignancy, as treatment with esomeprazole may alleviate symptoms and delay diagnosis. Decreased gastric acidity due to proton pump inhibitors increases gastric counts of bacteria normally present in the gastrointestinal tract and may lead to slightly increased risk of gastrointestinal infections such as Salmonella and Campylobacter, and possibly also Clostridium difficile in hospitalised patients. Concomitant use of esomeprazole and clopidogrel results in decreased exposure to the active metabolite of clopidogrel by an average of 40% and decreased maximum inhibition of platelet aggregation by an average of 14%, and should be avoided. Acute tubulointerstitial nephritis has been observed in patients taking proton pump inhibitors including esomeprazole, may occur at any point during therapy, and can progress to renal failure. Daily treatment with acid-suppressing medicines over a long period (longer than 3 years) may lead to malabsorption of cyanocobalamin (vitamin B-12) caused by hypo- or achlorhydria. Proton pump inhibitor therapy may be associated with an increased risk for osteoporosis-related fractures, particularly in patients receiving high-dose and long-term therapy (a year or longer). Hypomagnesaemia, symptomatic and asymptomatic, has been reported rarely in patients treated with proton pump inhibitors, with serious adverse events including tetany, arrhythmias and seizures. Severe cutaneous adverse reactions such as erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis and drug reaction with eosinophilia and systemic symptoms, which can be life-threatening or fatal, have been reported very rarely in association with esomeprazole treatment.

Contraindications

Known hypersensitivity to esomeprazole, substituted benzimidazoles or any other constituents of the formulation. Esomeprazole should not be administered with atazanavir. Esomeprazole is contraindicated in patients taking cilostazol.
