Question: are benadryl and zzzquil the same?
Answer: Benadryl is an allergy-relief brand; ZzzQuil is a sleep-aid line, so they've focused on marketing what is essentially the same product in different ways. “Yes, it is the same compound [DPH], but … for a person to sleep well with any product, they have to have a certain amount of trust in the product,” Dr. Pelayo says.
