Weno is easy enough and the drug database has the stuff i prescribe. It is free (for now).
It is easy to setup.
I followed the following instructions and have not had issues. I called them up and got the pharmacy database for my state, then I culled that down to pharmacies just my city and nearby areas and imported it into the openemr table. Was a bit of work but end in the end was worth it.
I make sure that the front check in staff selects a pharmacy for the patient.
