While not technically "renamed", it is deceptive to treat a patient of a medication they refuse and give to them anyway. This is deceptive business practice and quite lawsuit prone. This is why it's good to get in writing a signature from the doc that you are refusing a particular treatment, and if that's not available, record them. You are in a public place and have the right to record in most states without notifying them.

As it has to be said, I'm not a lawyer or attorney and this is not legal advice.
