How to write an rx

How to Write Prescriptions A prescription is an order that is written by you, the physician (or future physician), to tell the pharmacist what medication you want your patient to take. In this post, I’m going to break down all the different parts of a prescription, how to write each section, and what to look out for.

For as needed or pro re nata (PRN) prescriptions, you should indicate that the prescription is PRN and describe the conditions under which your patient can take the prescribed medication. Writing your prescription as a PRN order essentially gives the patient the option to take the medication when he or she needs it.

Even though I don’t think I caused any major harm to any of my patients with prescription errors, I wish I had read something like this when I first started writing prescriptions in my 3rd year of medical school.

"Rx" is the symbol for "superscription." Write it just before you write out your instructions for the medication itself. On most prescription forms, the "Rx" is already printed. Write the inscription information immediately after this symbol. The inscription includes all of the information about the specific drug you want to prescribe.
