My sister was given the wrong medication by her pharmasist ( Keppra ) she does not have epilepsy. He thought he had given her naproxen for the arthritis. She had take 500mg a day for the past 5 days. She called this morning to ask him if the meds were a new generic, this is when he told her to call her Dr and what had happened. She is depressed, not sleeping , hear races and said she thought about blowing her brains out she felt so bad. What kind of damage can this cause?
