what are the drug intereactions for cimetidine 800mg, ultram 50mg, oxycodone 15mg (not even a couple days ago it was norco 7.5 then switched to oxycodone), clonazepam 1mg, and unisom (doxylamine succinate 25mg)sleepingtab? I can pull up with one pill to the other but I need all in one?? Its V.I.P The doctor has a family member on these and after reading each individual intereactions with one I dont feel safe that they took all them in a days period. Its very critical that I know the intereactions as a whole, not this pill to this pill and so forth.
