Ok so they keep increasing his dose becuase his peak levels are not high enough. Is this something I should be worried about? The nurse told me that the pharmacist thought that his peak levels should be much higher but they weren't. I don't get it...they should be higher because they told me he is on a very high dose. The doctor told us we might be in longer than we thought. He is also on cefepime IV. Well any advice would be great. I am kind of devastaded over this whole pseudomonas thing. I wasn't expecting it. CF keeps knocking us down, but my little guy is so incredibly strong. I am so proud of him and so thankful that I get to be his mommy. Thanks guys for any advice. Hope everyone is well!
