An oblong pill marked with "P466" 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 can also be used as a nighttime sleep aid due to its sedative properties. Always consult with a healthcare professional before using this medication to ensure it’s appropriate for your needs.
