---

The white oval pill marked with "MP057" is identified as Diphenhydramine Hydrochloride 25 mg. Diphenhydramine is an antihistamine that is commonly used to relieve symptoms of allergy, hay fever, and the common cold. These symptoms include rash, itching, watery eyes, itchy eyes/nose/throat, cough, runny nose, and sneezing. It is also used to prevent and treat nausea, vomiting, and dizziness caused by motion sickness. Additionally, Diphenhydramine is often used as a nighttime sleep aid due to its sedative properties.

In terms of potency, Diphenhydramine is considered to be a moderately strong antihistamine. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms. The 25 mg dosage is typical for over-the-counter formulations, and it is generally effective for most individuals. However, the strength of the medication can vary based on individual tolerance and the specific condition being treated.

It's important to note that while Diphenhydramine is effective for many, it can also cause side effects, particularly sedation. Common side effects include drowsiness, dizziness, constipation, blurred vision, or dry mouth/nose/throat. Due to its sedative effects, individuals should be cautious when driving or operating machinery after taking this medication. Additionally, it is not recommended for use in children under the age of 6 without a doctor's advice, and caution should be exercised in older adults, as they may be more sensitive to the effects of the medication.

Patients with certain medical conditions, such as asthma, glaucoma, or prostate enlargement, should consult with a healthcare provider before using Diphenhydramine, as it may exacerbate these conditions. Furthermore, combining Diphenhydramine with alcohol or other sedatives can increase the risk of severe drowsiness and should be avoided.

In summary, the white oval pill marked "MP057" is Diphenhydramine Hydrochloride 25 mg, a moderately strong antihistamine used primarily for allergy relief and as a sleep aid. While effective, it is essential to use it responsibly and be aware of potential side effects and interactions with other substances. Always consult with a healthcare professional if you have any concerns or questions regarding its use.
