A pill marked U03 is identified as Diphenhydramine Hydrochloride 25 mg, which is an over-the-counter antihistamine commonly used to relieve symptoms of allergy, hay fever, and the common cold. It can help alleviate symptoms such as runny nose, sneezing, and itching. Additionally, it is often used as a sleep aid due to its sedative properties. Always consult a healthcare provider before use, especially if you have underlying health conditions or are taking other medications.
