What Causes Slurring Of Speech While On Atorvastatin And Diltiazem?

My wife is on a number of medications for multiple ailments. I fear that she is having a reaction to one or more of them. She is taking Prednisone, Diclofenac, Clobetasol, Azithromycin, Omeprazole, Docusate SOD, Levofloxacin, Bactrum DS, Flagyl, Vibratab, Lopid, Ranexa, Nebivolol, Diltiazem CD, Clopidogrel, Estradiol,
IC Atorvastatin, Oxycod/Acetamin, Lidocaine, Omeprazole, Prometh/COD, Gemfibrozil, plus natural stuff of
Omega 3 Fish Oil, Tumeric Root, B12, Turmeric Curcumin, and Vitamin C.
She is lethargic, uncoordinated, slurring, and combative when communicating.
Are these all colliding and she is experiencing the effects?
