Abstract: Drug delivery devices, finger-grip elements for use with syringes, and related methods are disclosed. A drug delivery device may include a syringe and a finger-grip element. The syringe may include a barrel, a barrel flange extending radially outwardly with respect to a longitudinal axis of the barrel, and a plunger moveably disposed within the barrel. The finger-grip element may be coupled with the barrel flange. The finger-grip element may have a first distally facing surface having a first contour configured to: inhibit or prevent at least a first finger of a user from moving in a radially outward direction with respect to the longitudinal axis during use of the syringe to deliver a drug, and/or exert a first reaction force on at least the first finger of the user in a direction parallel or substantially parallel to the longitudinal axis during use of the syringe to deliver the drug.
