Yep, known problem. They are trying to figure out a way to let us add without having to go to the summary page. I also have always added meds in this way. Sorry Bert you are correct, I should do it in the summary but the prescribing page is easier/faster.
This also happens with supplements and OTC meds. Even if I ask a pt to add on a supplement it becomes an issue. I did "prescribe" the supplement but now it won't save to the chart. I posted about this earlier and have discussed with AC on a couple of occasions. You can try print to PDF to save some paper but this is the only work around at this time that we have found. I tried the pdf print the other day and it didn't seem to work but it has in the past. I'll try again today and post back.
Hopefully ACZ they will contact you about what you see and how best to change in the next version. I have given my ideas.
