Why do drug dosages have to be changed after a certain amount of time?i thought the body only builds immunity and starts to resist disease. if a...

Let's take a specific example, not with disease but with
an injury that involves inflammation whether it is tendonitis or some kind of sprain,
etc.


Someone might take an anti-inflammatory whether it is
ibuprofen or naproxen sodium to treat this problem.  If we assume they are an avid
runner, they get some relief from the problem, perhaps they are even icing the injury
regularly so they can continue training.


If they continue
to take the anti-inflammatory and the problem is not resolved, eventually the body stops
producing the anti-inflammatory response it used to because the drug is doing it for
them.  So they have to take more and more of it for the same
effect.


Similar things can happen with other drugs for
other problems as well.  The body always tries to be as efficient as possible and if
something is doing its work for it, it will redirect that energy
elsewhere.
