Yes, make sure to check with your Dr. S/He doesn't have to approve, they just need to tell you if they will conflict with your medications.
For instance, Lupus gives us overactive immune systems, so our meds help us by reducing the action of the immune system, trying to get to a normal balance. Then, if you took something designed to "boost" the immune system, it'd be totally out of balance again, and you would have wasted all the time/money on Dr, meds, & supplements!
