Not wasted actually.
Once you hit the cap of 255 for a consumable, the game stops giving you that sort of consumable in the standard sorts of packs. If you only have one type of consumable you can get, both drops in a pack will be of that sort of consumable. For instance, I usually have 255 for missiles, ops packs and ammo, which means I get nothing but Medigel in my packs.
Useful if, like me, you find yourself running critically low on medigel and need to boost it back up fast.
