Mom is in the hospital. Started steroid and antibiotic today, and it's seriously affecting her cognition. Anyone else?

She's on cefzil and prednisone. I'm wondering if she'll get back to normal after this. She desperately needs these medications. We arrived at 1am Sunday morning, and her cognition was on par withĺ before the meds...then after these meds it all went south within 30 minutes. Thank you
