What is more common in fatal caffeine intoxication - suicide or unintentional overdose?

Abstract

Caffeine is a natural stimulant of plant origin found in many products such as coffee, tea, chocolate, and energy drinks. It is also often used as an active substance in over-the-counter drugs such as painkillers and preparations for the treatment of colds and allergies. While caffeine is generally considered safe when moderately consumed, excessive intake in a single dose or through repeated small doses over time can lead to caffeine intoxication. Symptoms of caffeine intoxication can vary depending on the amount of caffeine consumed and can include restlessness, rapid heart rate, muscle tremors, nausea, vomiting, and confusion. In severe cases, caffeine intoxication can lead to convulsions, coma, and even death. This mini-review presents an overview of caffeine's characteristics and intoxication including symptoms, causes, diagnosis, and treatment. It addresses risk factors associated with caffeine intoxication and presents current recommendations for safe caffeine consumption. The studies we have reviewed suggest that in cases of fatal caffeine intoxications, intentional intoxication is more common than unintentional.
