There is probably an existing thread on this topic, but I'll ask anyway! <img src="i/expressions/face-icon-small-smile.gif" border="0"> DD is starting HTS and was advised to administer HTS prior to Pulmozyme with essentially no wait time in between. I understand that HTS can decrease the efficacy of the Pulmozyme which is why they advised not to give Pulmozyme first. However, administering Pulmozyme immediately following HTS still seems too close...am I wrong?<br><br>Just sent an email to her CF nurse regarding the volume of HTS to administer. We received 15mL vials...<br>
