What does an epi pen look like?

An EpiPen is a sleek, cylindrical device that typically measures about 5 to 6 inches in length and is about 1.5 inches in diameter. It usually features a colored cap at one end, which is removed before use, and a clear window showing the medication inside. The device often has a push-button mechanism for easy administration of the epinephrine. EpiPens are commonly packaged in a hard plastic case for protection and portability.
