The pharmacy that is in the outpatient clinic complex where my clinic is doesn't even carry HTS. I don't know about the Children's Hospital Pharmacy. The CF Services Pharmacy sends it in the 10% and .9% to mix in a vial for 7%, and that is the only way I have found to get it locally, either (now I use a local pharmacy- it's cheaper <img src="i/expressions/face-icon-small-wink.gif" border="0"> ). It was an aggravation to mix it at first, but now I have 2 measuring vials, so I throw them in with the nebs at the end of the day and don't have to worry about forgetting to sterilize it and waiting on it, etc. Now it's no big deal <img src="i/expressions/face-icon-small-wink.gif" border="0"> .
