The 454 pill is identified as Diphenhydramine Hydrochloride 25 mg, an antihistamine commonly used to relieve symptoms of allergy, hay fever, and cold, such as runny nose, sneezing, and itching. It is also used as a nighttime sleep aid due to its sedative properties. The pill is typically oval and pink in color, with "454" imprinted on one side. As with any medication, it's important to use it as directed and consult a healthcare professional if you have questions or concerns.
