How Long Does Benadryl Stay in Your System?

Answer

Benedryl stays in your system for roughly 7-18 hours, depending on your metabolic rate and weight. Within 6-12 hours, it's technically not helping you anymore, and you'll want to take more. If you take twice the normal dose, you could have a measurable amount still in your system for more than 24 hours.
