1. A drug delivery device that is configured to be primed in a priming step, wherein priming is a step carried out before injecting the first volume of a drug so that the user can dispense the intended dose accurately, the drug delivery device comprising:

a device body,

an operating member which is configured to be movable relative to the device body to perform two actions, a priming action and a dose delivery action, where the operating member is further configured such the priming action must occur before the dose delivery action,

a preventing member which prevents movement of the operating member relative to the device body for operating the drug delivery device and which prevents the priming action,

characterized in that the preventing member is removable from the drug delivery device to allow the movement of the operating member relative to the device body.

2. The device according to claim 1 , wherein the device is in an un- primed condition when the preventing member is present.

3. The device according to claim 1 , wherein priming the device is allowed only when the preventing member is removed.

4. The device according to claim 1 , wherein the device can be primed when the preventing member is removed, by moving the operating member relative to the device body.

5. The device according to claim 1 , wherein the operating member is positioned such that after the preventing member is removed, a priming step can directly be performed.

6. The device according to claim 1 , wherein the operating member is positioned such that after the preventing member is removed, a pre-priming step is necessary before the priming step can be performed.

7. The device according to claim 1 , wherein the preventing member is arranged partly on the operating member and partly on the device body.

8. The device according to claim 1 , wherein the preventing member is arranged circumferentially with respect to the operating member.

9. The device according to claim 1 , wherein the preventing member is arranged partly inside the device and partly outside the device.

10. The device according to claim 1 , wherein the removable preventing member is connected to a label.

11. The device according to claim 10 , wherein information for using the device is provided on the label.

12. The device according to claim 1 , wherein information for priming the device is provided on the preventing member.

13. The device according to claim 1 , wherein the preventing member comprises a grip-tab.

14. The device according to claim 1 , wherein the primed device is a fixed dose device.

15. The device according to claim 1 , wherein the device is a pen-type injector.
