Can i use norfloxacin to treat my urinary infection if i have hepatitis b. is it safe for my liver?

Questionable: Caution is advised in the use of Norfloxacin in the presence of liver impairment. Since there are many alternate drugs for treating uti, your doc may prefer to select one of those (probably after a urine culture to determine which drug is best). If Norfloxacin is the best choice, your doc will probably monitor your liver function tests before & during administration to prevent serious adverse fx.
