Thankyou, hallo my name is Margaret; my question is that I have a dear friend whose husband is on dialysis 3 times a week, he is 63 years of age and has been in renal failure for several years. My deep concern is that during the resent petite grand mal seizure, with two previous ones in the past two months, and hospitalized now with a 9 kidney output. He has been given the drug Valprocic acid and I understand their are serious, if not fatal side effects with liver damage for one. He is not bi-polar This drug along with Benzodiazapin given him, could they be doing prolonged damage.
