Seems a little ridiculous that you can't put quantities in ounces or grams when a ton of meds are Rx'ed that way. Or how about patches? Is it the Amazing Charts side of things or the generic eRx thing? There could be a second pull down menu even! or make the box able to be free text. The pull down menu is unneccessary for how many pills anyway. Just type it in.
Seems like such a simple fix by which ever side the fix needs to be done on.
