Stop selling ZzzQuil as a new medicine. It is old! It is not new, but it costs over 4 times as much per dose as what it really is - diphenhydramine (Benadryl), a very old medication, generally sold to relieve allergy symptoms.
Why is this important?
Proctor and Gamble is advertising ZzzQuil as a "new sleep aid".
It is not new, but merely Benadryl (Diphenhydramine), an old allergy medication that has been on the market for a very long time.
