Depends on dose, how much and often you take it, etc.. 
The half-life of Motrin is approx 2 hours, means that after 2 hours, only half of the active dose is still present in your system. For example prescription dose of 800mg will exit your metabolic system in 3-5 days.

Wrong half life.  Motrin has a half life of 1.8 - 2.0 hrs.  It is completely out of your system in 24 hrs.
