This Is A New Medication My Mom's Cardiologist Prescribed To

This is a new medication my mom's cardiologist prescribed to her several weeks ago due to a cardioversion failed after 3 attempt. She's experiencing pressure in her head and also nausea but just in the last day she's now experiencing itching, burning, rash and pain over her entire body. It disappeared for a few hours and how now returned. Could this medication cause these symptons?
