Yes, if something such as Lexapro, Cymbalta or Effexor (among the most commonly prescribed for anxiety and depression) don't work sufficiently, then many psychopharmacists will add 1 or more meds to try to stabilize mood, increase energy, etc. I think that the best way to look at antidepressants, etc. is that the goal is to lessen anxiety or depression sufficiently to allow the individual to engage more fully in life.
