Still Coughing

After a week on Cephalexin, Emery still wasn't getting better.  She's been coughing all day and all night and she's VERY congested.  On Wednesday I called the clinic and they told me to go ahead and bring her in.  They swabbed her nose and throat and said they would let me know what they find out.  I got an email saying that her viral cultures were negative and that after 48 hours her bacterial cultures had only grown "normal flora."  The bacterial culture wasn't final yet so we'll know more on Monday.  

Dr. R went ahead and switched her to a different antibiotic since the other one wasn't doing anything for her.  Now she is taking Bactrim.

So that's where we are for now.

My main question was "why are we giving antibiotics if there isn't anything showing up on her cultures?"

Here is the answer I got:
"One reason is that the culture was obtained as a throat swab and most of the time that gives an adequate representation of what is in the lungs (without having to be more invasive).  However, there may be times when what grows in the throat may not be the same as what grows in the lungs."

"The other thing is that the lung disease of CF is progressive so people with CF typically don't have the luxury of letting things just "run its course."  With each flare-up of the lung disease there is the possibility of permanent changes to the lungs so we need to be as proactive as we can in keeping people with CF well and treating aggressive early"
