Abstract

Caffeine is one of the most frequently used stimulants worldwide. It is, therefore, subject to frequent intentional and unintentional misuse. However, severe erosive esophagitis due to acute caffeine overdose is extremely rare. We report the case of a 43-year-old male with a past medical history of paranoid schizophrenia admitted to our hospital with esophageal symptoms (throat pain, retrosternal chest pain, dysphagia/odynophagia, nausea, and vomiting) two days after ingesting a bottle of caffeine pills containing about 30 g of caffeine in a suicide attempt. He was found to have rhabdomyolysis and acute renal failure warranting hemodialysis. Esophagogastroduodenoscopy done due to persistent retrosternal chest pain, dysphagia, odynophagia, and nausea despite being on oral famotidine 20 mg daily revealed severe erosive esophagitis. This case highlights the risk of concurrent renal and gastrointestinal injuries after acute ingestion of an excessive amount of caffeine tablets. Our experience suggests that in patients of caffeine overdose with persistent esophageal symptoms such as odynophagia, dysphagia, and retrosternal chest pain, endoscopic evaluation is advisable to rule out drug-induced esophagitis.
