Shouldn't be: You're taking a fairly low dose of both Prozac and Valium ... But, yes, because of the way Prozac is metabolized, it will effect the concentration of Valium. That said, if you're having acute anxiety and depression - perhaps have a discussion with your doctor about another medication which might be more appropriate for you (such as Cymbalta (duloxetine) or Pristiq). Hope that helps!
