Medication Error Prevention Strategies in Pharmacy

Common Error Types

Medication errors can occur at any point in the medication-use process: prescribing, transcribing, dispensing, administering, and monitoring. Common dispensing errors include wrong drug (especially look-alike/sound-alike medications), wrong strength, wrong quantity, and wrong patient. Understanding error types helps prevent them.

Tall Man lettering is used to differentiate look-alike drug names by capitalizing the differing portions. For example, hydrOXYzine vs. hydrALAZINE and predniSONE vs. prednisoLONE. The FDA and ISMP maintain lists of confused drug pairs.

Prevention Strategies

Key prevention strategies include barcode scanning at every dispensing step, independent double-checks for high-alert medications, separating look-alike medications on shelving, and creating a culture of safety where errors are reported without punishment.

The "five rights" of medication safety are the right patient, right drug, right dose, right route, and right time. Pharmacy technicians should verify these at every step of the dispensing process.

Exam and Practice

Patient safety is a core PTCB domain. Review with flashcards and practice with mini exams.
