Which of the following must be included in a patient’s medication profile?

Including the patient's medical history, particularly allergies, in a medication profile is crucial for ensuring safe and effective medication management. The presence of allergies is vital information that can significantly impact drug selection and treatment plans. Knowing what substances a patient is allergic to helps pharmacists and healthcare providers avoid prescribing medications that could trigger an allergic reaction, thus safeguarding the patient's health.

Other components, like insurance information or a social security number, are important for administrative and billing purposes but do not directly influence medication safety or effectiveness in the same way that knowing a patient's allergies does. A pharmacist's personal contact number is also not relevant to the patient's safety regarding their medications. Therefore, the inclusion of the patient's medical history, particularly allergies, is essential in creating a comprehensive and safe medication profile.
