Whenever you multiply drugs you increase the chances of problems both because every drug ever made has side
effects and is somewhat toxic and because the drugs also interact in a multiplying way that can be
adverse. There is a warning about combining these drugs, so the risk is there, but again, that doesn't mean it will happen to you. It's a cost/benefit analysis you have to do whenever you take medication and whenever you combine meds. The real question is, how is your life going?
