On September 15, 2004 I saw a lady for low back pain and gave her a script for Percocet.
For whatever reason, she never had the script filled, just shoved it in a drawer at home. She never followed up with me.
Yesterday she apparently found the script buried in the drawer, and decided she should get it filled. She figured (correctly) that the pharmacy wouldn't fill anything that was written 5 years ago.
So she changed the date on it to September 15, 2009, and took it to Walgreens.
The pharmacist who called me was laughing so hard he was crying.
