We've had issues with leucovorin lately. I've noticed that it's being ordered PO routinely. Normally I wouldn't have a problem, but waking up a 6 year old at 0300 to take a pill is rather unpleasant. Our docs are frustrated with it and can usually be counted on to order a PRN IV specifically for the middle of the night doses. I'm assuming in the adult world patients don't get that luxury
Thankfully, I've never had to tell a family "sorry, your kid can't get chemo because we don't have any" but that list scares me!
