Step-by-step explanation:
A Personal Health Record (PHR) allows clients to keep track of all medications and their side effects, dosages, prescribing doctors, and the purpose of the medication. By maintaining a PHR, individuals can ensure that they and their healthcare providers have access to accurate and up-to-date information which is vital for safe and effective medication management. Not only does this help in preventing adverse drug interactions, but it also aids in communication during doctor visits or emergencies.
