Hi, my wife is taking 2g Cefepime through a pic line at home to treat an ear bacteria. This delivery method is being used because she is pregnant. She just accidentally took about 5mL of one that was dated to be discarded after 7/9. She stopped as soon as she realized, we went through a disposed of the old, and has another, current dose ready. How worried should we be? Should she take all 20mL of the current dose or only 15mL?
