What is the max amount of benadryl (diphenhydramine) i can take in a day?
A doctor has provided 1 answer
Technically, 300mg : I don't recommend taking more than 100mg (25mg every 6 hours) without physician input, as that can be extremely sedating. That said, technically the dose is 25-50mg every 4-6 hours. If you take 50mg every 4 hours that makes 300 mg.
