The small white pill marked "M 550" is identified as Diphenhydramine 25 mg, an antihistamine commonly used for Allergies, hay fever, and insomnia. It is not intended to be injected; doing so can be dangerous and lead to serious health complications. Always use medications as directed by a healthcare professional and avoid methods of administration that are not approved for the specific drug.
