In medicine, the sign 'R/' or 'Rx' is often used to denote prescription or treatment.
I use it a lot when taking notes in class and I'd like to use it in my LaTeX documents, too. The problem is that it's hard to find out how to write this in LaTeX, because searches like 'latex medicine' or 'latex prescription' will be overflooded by pages about latex allergies.
How can I write this sign in LaTeX?
