FPGEE for National Association of Boards of Pharmacy (NABP) Practice Exam 2026 - Free NABP Practice Questions and Study Guide

The Naranjo ADR Probability Scale consists of 10 questions designed to help determine the likelihood that an adverse drug reaction (ADR) is indeed caused by a specific drug. Each question on this scale assesses different factors related to the patient's clinical history, the timing of the drug administration in relation to the occurrence of the ADR, and existing evidence of the drug's effects. The total score from these questions helps classify the ADR into categories such as definite, probable, possible, or doubtful. This structured approach allows healthcare professionals to evaluate ADRs systematically, thereby facilitating better pharmacovigilance and patient safety measures.
