Pharmacy Technician Certification Board Practice Exam

Which of the following medications must be stored in a refrigerator?

1. NovoLog

2. EpiPen

3. NuvaRing

4. Pneumovax 23

The correct answer is: NovoLog

NovoLog, an insulin analog used to control blood sugar levels in individuals with diabetes, requires refrigeration for proper storage. Insulin medications can lose their potency if left at room temperature for extended periods, which could diminish their effectiveness. Therefore, to ensure stability and maintain the medication's efficacy, NovoLog is typically stored in a refrigerator. In contrast, while an EpiPen (epinephrine auto-injector) is often mentioned with storage recommendations, it should be kept at room temperature and protected from extreme heat and light. NuvaRing, a contraceptive vaginal ring, can also be stored at room temperature prior to use. Pneumovax 23, a vaccine for pneumococcal disease, requires refrigeration, but it does not need to be frozen. Thus, understanding the specific storage needs of each medication is essential to ensure they are effective and safe for use.
