I would say probably yes. There should be no interaction or side effects from them based on what I have researched, but I would speak to a pharmacist to make sure b/c no research gave me a direct answer, just "more than likely" probabilities. I am not a doctor, although I have a psyc. degree and know alot about all kinds of medicines, not just psyc. meds, I am not going to tell you "yes it is perfectly fine, do it". More than likely it is, but back it up with proper advice from a professional. If it is too late to call pharmacy, u can always call ER at hospital and ask for advice on drug interactions.
