An injector pen (also called a medication pen) is a device used for injecting medication under the skin. First introduced in the 1980s, injector pens are designed to make injectable medication easier and more convenient to use, thus increasing patient adherence. The primary difference between injector pens and traditional vial and syringe administration is the easier use of an injector pen by people with low dexterity, poor vision, or who need portability to administer medicine on time. Injector pens also decrease the fear or adversity towards self-injection of medications, which increases the likelihood that a person takes the medication.
Injector pens are commonly used for medications that are injected repeatedly by a person over a relatively short period of time, especially insulin and insulin analogs used in the treatment of diabetes (called insulin pens). Many other medications are also available as injector pens, including other injectable medicines for diabetes, high cholesterol, migraine prevention, and other monoclonal antibodies. Studies have shown injector pens to be at least as effective as vial and syringe administration, and surveys have shown that a vast majority of people would prefer an injector pen over vial and syringe administration if one was available. After a slow uptake in the United States, injector pens have surpassed vial and syringe administration of insulin in type 2 diabetes.
