My 82 Year Old Mother Was Prescribed 300mg Of Gabapentin

My 82 year old mother was prescribed 300mg of gabapentin tid as well as 50 mg tramadol which she took this am. She fell. She stated that while cooking and things just gave out. I am wondering if this is to much mediation for her. She has severe back pain, pulmonary fibrosis and has an internal defibrillator.
