Brian, handwritten Rx have issues too. Alot of patients here in NYC seem to call back and say "I lost my prescription, can you call it in?" After we got tired of this, we began assuming that they had not lost it, but just didn't want to wait at the pharmacy (or make 2 trips). Kind of cynical, but its NYC.
Now, if they lose their Rx, they must come by and pick up a new one--even if its just for ibuprofen. We had some angry patients, and lost a few, but now its been 3-6 months since anyone called in claiming that they lost the Rx. All the get-over artists are pulling this trick on other doctors now.
