Maybe add it to the surgical tables, that way you have to be physically lying down in order to use it and you're stuck in either medbay or pharmacy while your blood is drained.

Calomel lets you clean the blood stream anywhere and also works as a poison.

That's why I suggest that it's somewhere hard to get to without the assistance of a doctor. That way it's not as convenient as calomel. Maybe in the room with the cryo chamber.
