A white round pill imprinted with "381" on one side and a "b" on the other is identified as Diphenhydramine Hydrochloride 25 mg, which is an over-the-counter antihistamine commonly used to relieve symptoms of Allergies, hay fever, and the common cold. It is also used as a sleep aid due to its sedative properties. Always consult a healthcare professional before taking any medication.
