An autoinjector comprising:
- a pump including a reservoir for holding a medication and an outlet associated with the reservoir for discharging the medication;
- a working side at which the medication is deliverable from the pump, and a non-working side opposite the working side;
- a housing holding the pump, the housing having at least one finger grip proximally located to the working side.
A method for using an autoinjector, the method comprising:
- providing an autoinjector that has a pump that includes a reservoir that holds a medication and an outlet associated with the reservoir for discharge of the medication therefrom, a housing that holds the pump, the housing has a working side at which the medication is deliverable from the outlet, a non-working side opposite the working side, and at least one finger grip proximally located to the working side;
- inserting at least one finger into the at least one finger grip with a nail-side of the at least one finger facing the non-working side;
