i havent been giving meds constant, all these meds are over a period of time. i just got a whole lot of fortaz so ill be starting that once the other meds have died down a bit. i know i wont get a full recovery just from neulization but it sure has helped break things up and make her breathing easier. she also has some fluid down in her lungs so i figure it would be good to get some meds right at the bacteria
