-my father is recieving three injection of Neupogen(Filgrastim) ( 30 MU ) after every chemotraphy, starting 48 hours after chemotraphy with 48 hours interval beween every injection.

-Last Monday (8 of Sep. 2014) for the second injection, a three months expired but keeped in refrigarator Neupogen is injected by mistake, what may be the danger or threat?

-He is feeling weak after that day and sleeps most of the time, also i should mention that we discard all expired neupogens that was left in refrigerator

-The third injection was today (10 of Sep.) with an ok Neopogen

-Should we have an extra Neuopogen injection for him instead of the expired one 48 hours after now?

Thanks in advance
