A pen needle includes a hub supporting a needle and a distal needle shield that can retract to expose the needle and return to an extended position to cover the needle. A proximal needle shield moves to an extended position to cover a proximal end of the needle. A spring extends between the distal and proximal needle shields to bias the distal and proximal needle shields to their respective extended positions. A locking member on the distal needle shield cooperates with the hub to lock the proximal and distal needle shields in their respective extended positions. An indicator in the hub couples to the distal needle shield when the distal needle shield is moved to a retracted position. The indicator moves with the distal needle shield to the extended position of the distal needle shield where the indicator indicates that the pen needle is no longer usable.
