You could just do:

function RetryFunction()
if not IsCollectibleActive(#) then
     UseCollectible(#)
else
     EVENT_MANAGER:UnregisterForUpdate("Refire")
end

function DoThat****MyDude()
     UseCollectible(#)
     EVENT_MANAGER:RegisterForUpdate("Refire", RetryFunction, 100)
end

Function will just keep trying every 100 ms until it gets used. Might want to put a counter variable on it too so it times out after a few seconds if not.
