Caffeine cannot sober a drunk or save someone who is lethargic or unconscious from an overdose of a sedating drug. However, because caffeine lowers stomach pH, it can affect the absorption of other substances. Other drugs such as oral contraceptives, cimetidine, disulfiram, and alcohol can delay the body’s ability to rid itself of caffeine.
