Stuff like this gets used in cancer treatments, too, with combination therapies [1]. Even more interesting are drug holidays: cancer becomes resistant to drug A by evolving a new clone that uses some other metabolic pathway unaffected by the drug but is less efficient. Stop drug A, the first more efficient clone takes over again. Give drug A again and there is no resistance for a while.
