A medication therapy review is a one-on-one consultation between a pharmacist and a patient during which the pharmacist gathers information about the patient's health issues and all drugs that he or she is taking, whether prescribed, over-the-counter, or a natural health product. The pharmacist will examine each drug to ensure that it is suitable, effective, and safe, with no side effects or interactions. A key aspect of the review is patient education. The pharmacist explains to the patient what each drug is for and how to take it properly and how are those working together to support your overall health and wellness.
