To work as a pharmacy technician in a pharmacy that compounds chemotherapeutics, you would typically need to have a high school diploma or GED. You would also need to complete a pharmacy technician training program and pass an exam to become certified. Once you are certified, your duties may include preparing chemotherapy medications, maintaining inventory, and communicating with patients and healthcare providers about medication use and side effects. It is important to follow safety protocols and maintain a sterile environment to ensure that the medications are prepared correctly and safely.
