Prescription Writing 101

Prescription writing is something that I used to worry so much about in my 3rd year of medical school. I probably killed a whole tree tearing up prescriptions that were wrong. Why did I worry so much about it? Prescription writing was not covered very well at my medical school. And with the amount of material that needs to be covered in those 4 years, I’m sure writing prescriptions is not that well covered at any medical school. Maybe that’s one of the reasons there are so many medication errors in medicine. Look at some of these commonly quoted statistics:

  • Medication errors occur in approximately 1 in every 5 doses given in hospitals.
  • One error occurs per patient per day.
  • 1.3 million people are injured and approximately 7000 deaths occur each year in the U.S. from medication-related errors
  • Drug-related morbidity and mortality is estimated to cost $177 billion in the U.S.

While these are just estimates from various studies and statistical models, the numbers are staggering. If there are 800,000 physicians in the United States, each physician accounts for $221,250! Do you still wonder why malpractice insurance is so expensive?

Hopefully if you are reading this, you are interested in NOT making mistakes. Even though I don’t think I caused any major harm to any of my patients with prescription errors, I wish that I had read something like this when I first started writing prescriptions when I was in my 3rd year of medical school.


A prescription is an order that is written by you, the physician (or medical student with signature by a physician) to tell the pharmacist what medication you want your patient to take. The basic format of a prescription includes the patient’s name and another patient identifier, usually the date of birth. It also includes the meat of the prescription, which contains the medication and strength, the amount to be taken, the route by which it is to be taken and the frequency. Often times, for “as needed” medications, there is a symptom included for when it is to be taken. The prescriber also writes how much should be given, and how many refills. Once completed with a signature and any other physician identifiers like NPI number or DEA number, the prescription is taken to the pharmacist who interprets what is written and prepares the medication for the patient. Let’s break it down.

Patient Identifiers

According to the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) national patient safety goals, at least two patient identifiers should be used in various clinical situations. While prescription writing is not specifically listed, medication administration is. I think prescription writing should be considered in this category as well. The two most common patient identifiers are full name and date of birth. These are the FIRST things to write on a prescription. This way you don’t write a signed prescription without a patient name on it that accidentally falls out of your white coat and onto the floor in the cafeteria.


This is an easy one. This is the medication you want to prescribe. It generally does not matter if you write the generic or the brand name here, unless you specifically want to prescribe the brand name. Remember, if you do want the brand name, you specifically need to tell the pharmacist – “no generics.” There are several reasons why you would want to do this, but we won’t get into that here. On the prescription pad, there is a small box which can be checked to indicate “brand name only” or “no generics”.


After you write the medication name, you need to tell the pharmacist the desired strength. Many, if not most, medications come in multiple strengths. You need to write which one you want. Often times, the exact strength you want is not available, so the pharmacist will substitute an appropriate alternative for you. For example, if you write prednisone (a corticosteroid) 50 mg, and the pharmacy only carries 10 mg tablets, the pharmacist will dispense the 10 mg tabs and adjust the amount the patient should take by a multiple of 5.


Using my previous example for prednisone, the original prescription was for 50 mg tabs. The prescriber would have written “prednisone 50 mg, one tab….” (I’ll leave out the rest until we get there). The “one tab” is the amount of the specific medication and strength to take. Again using my previous example, the instructions would be rewritten “prednisone 10 mg, five tabs….” You can see that “one tab” was changed to “five”. Pharmacists make these changes all the time, often without any input needed from the physician.


Up until this point, we have been using plain English for the prescriptions. The route is the first opportunity we have to start using English or Latin abbreviations. A NOTE: it is often suggested that to help reduce the number of medication errors, prescription writing should be 100% English, with no Latin abbreviations. I will show you both and let you decide. There are several routes by which a medication can be taken: By Mouth (PO), Per Rectum (PR), Sublingually (SL), Intramuscularly (IM), Intravenously (IV), Subcutaneously (SQ)

As you can see, the abbreviations are either from Latin roots like PO – per os – or just common combination of letters from the English word. Unfortunately when you are in a hurry and scribbling these prescriptions, (there is a truth behind never being able to read a physician’s hand writing) many of these abbreviations can look similar. For example, intranasal is often abbreviated “IN,” which, when you are in a hurry, can be mistaken for “IM” or “IV.” Check this out:

Common Route Abbreviations:

  • PO (by mouth)
  • PR (per rectum)
  • IM (intramuscular)
  • IV (intravenous)
  • ID (intradermal)
  • IN (intranasal)
  • TP (topical)
  • SL (sublingual)
  • BUCC (buccal)
  • IP (intraperitoneal)

The frequency is simply how often you want the prescription to be taken. This can be anywhere from once a day, once a night, twice a day or even once every other week. Many frequencies start with the letter “q.” Q if from the Latin word quaque which means once. So it used to be that if you wanted a medication to be taken once daily, you would write QD, for “once daily” (“d” is from “die,” the Latin word for day). However, to help reduce medication errors, QD and QOD (every other day) are on the JCAHO “do not use” list. Instead you need to write “daily” or “every other day.”

Common Frequencies Abbreviations:

  • daily (no abbreviation)
  • every other day (no abbreviation)
  • BID/b.i.d. (Twice a Day)
  • TID/ (Three Times a Day)
  • QID/q.i.d. (Four Times a Day)
  • QHS (Every Bedtime)
  • Q4h (Every 4 hours)
  • Q4-6h (Every 4 to 6 hours)
  • QWK (Every Week)
The “Why” Portion

Many prescriptions that you write will be for “as needed” medications. This is known as a “PRN” (from the Latin pro re nata, meaning as circumstances may require). For example, you may write for ibuprofen every 4 hours “as needed.” What is commonly missed is the “reason.” Why would it be needed? You need to add this to the prescription. You should write “PRN headache” or “PRN pain” so that the patient knows when to take it.

How Much

The “how much” instruction tells the pharmacist how many pills should be dispensed, or how many bottles, or how many inhalers. This number is typically written after “Disp #.” I highly recommend that you spell out the number after the # sign, though this is not required. For example: I would write “Disp #30 (thirty).” This prevents someone from tampering with the prescription and adding an extra 0 after 30, turning 30 into 300.


The last instruction on the prescription informs the pharmacist how many times the patient will be allowed to use the same exact prescription, i.e. how many refills are allowed. For example, let’s take refills for oral contraceptives for women. A physician may prescribe 1 pack of an oral contraceptive with 11 refills, which would last the patient a full year. This is convenient for both the patient and physician for any medications that will be used long term.

Prescription Writing Examples:
Prescription Writing 101 - Example

This example is a common medication prescribed when people are leaving the hospital. It is one 100 mg tablet, taken at bedtime. The prescription is for 30 pills and no refills.

Prescription Writing 101 - Example 2

Zofran is a very popular anti-nausea medication used after surgery. You’ll notice this script is missing the “amount.” IV medications are a little different in that the amount and strength are kind of mixed together. This is not always the case though. You also see that this is an “as needed” or “PRN” medication. When the patient complains of nausea, the nurse can give this medication because it has been prescribed.

Prescription Writing 101 - Example 3

This example shows a common way to write prescriptions for liquids, especially for children. Obviously “liquid” isn’t the medication, but you get the idea. Liquids come in specific strengths per amount of liquid. Here, the strength is 10 mg per 5 mL. We only want to give 5 mg though, so the “amount” that we prescribe is only 2.5 mL per dose. It’s given by mouth every 4 hours. We are dispensing “1 (one) bottle”. You could also just write “1 (one)” as the pharmacist would know what you meant.

To finish up, here is a list of the JCAHO “Do Not Use” List:

  • U or u (unit) – use “unit”
  • IU (International unit) – use “International Unit”
  • Q.D./QD/q.d./qd – use “daily”
  • Q.O.D./QOD/q.o.d./qod – use “every other day”
  • Trailing zeros (#.0 mg) – use # mg
  • Lack of leading zero (.#) – use 0.# mg
  • MS – use “morphine sulfate” or “magnesium sulfate”
  • MS04 and MgSO4 – use “morphine sulfate” or “magnesium sulfate”

    Today I have wrote a prescription for lorazepam 0.5 mg following ECT for post ICTAL irritability. The ECT occurs once every 3 weeks.

    I wrote the RX as follows: Lorazepam 0.5 mg po upon return from ECT session 1x every 3 weeks.
    The nursing home director wants me to an add a prn after the order as on holidays, ECT schedules can change to other days. To me if you place a prn after the order it makes it an “as necessary” RX. I want it scheduled following the ECT. How can I write this to allow for varying schedules?

    • Ryan Gray, MD on November 1, 2012 at 6:22 pm

      Great Question!

      You would write the script for Lorazepam 0.5mg po every ECT prn irritability.

      The “as needed” is for post ictal irritability so thats the prn you would write. The frequency is every ECT.


      • Francisco Mata on August 6, 2013 at 5:58 am

        I just want to ask. I am a pharmacist and I had this hot argument with a physician with regards to her prescription writing of Valium 10 mg tablet.

        She prescribed Valium 10 mg tablet 1 tablet at bedtime as needed for insomnia #20. I made a suggestion to revise the signa to 1 tablet every bedtime as needed for insomnia, in order to fill the whole quantity.

        She got mad after correcting her and she said she is a doctor she doesn’t need to be corrected since the signa is already correct..

        I’d love hearing from your answer. Thanks!

        • Omar on September 10, 2014 at 1:44 pm

          1 tablet at bedtime is proper, 1 tablet “every” bedtime lends itself to misinterpretation. A pt. may claim multiple “bedtime hours” in a 24 hr. period to justify taking more than one dose.

  2. Cat on November 1, 2012 at 5:56 pm

    Oops “wrote” ….

  3. jnilebarnes on January 29, 2013 at 1:43 pm

    IF you update this, please include INDICATION EVERY TIME. This is a great check for pharmacists to be sure the drug is appropriate for the indication, to avoid errors. In some states this is actually law (Texas, makes it law, but has a weasel out clause when “knowing the indication is not in the patient’s best interest” A left over from more paternalistic days.

    • Ryan Gray on January 29, 2013 at 9:11 pm

      @jnilebarnes I like it. I’ll try to find a list of states that do require it and put that as well! Thanks!

      • Henry on March 13, 2015 at 5:36 am

        MD’s should also include a diagnosis (Dx) on all controlled prescriptions, especially Schedule II medications. Sometimes the diagnosis is needed for insurance billing as well.

  4. Individual with Interest on February 1, 2013 at 11:08 am

    You might write another article to clarify “dispense as written.”  The article could include brand necessary, generic substitution allowed, and generic DAW (for example: generic by specific manufacturer).  The generic DAW information would include whether it would be more clear to write (BRAND NAME) generic DAW or (GENERIC NAME) DAW and why a generic daw would prevent brand being dispensed when the pharmacy might be able to dispense brand as generic.

  5. stephen on August 18, 2013 at 1:09 am

    could you do a sample for desmopressin (DDAVP) 10 mcg IN. patient takes 2 times daily (morning and evening) with 3 repeats. it comes in a bottle, does the Rx need to say one bottle? thanks

    I have a prescription for Percocet 7.5/325, ‘y: 1 tab q 4-6 hrs PRN mod-severe pain #30 Thirty 1 refill

      Not sure – that’s interesting

    • RK on February 9, 2015 at 2:09 pm

      probably that a generic substitution is permissible.

      Alprazolam 2mg P.O. T.I.D. P.R.N #90 (most docs put PRN for benzodiazapines [unless for seizures] or pain meds. It means as needed. So there you go that says Xanax 2mg by mouth three times a day as needed dispensed as 90 tablets.) I see a psychiatrist and am on a ton of psych meds. I always read my scripts before I leave. Too many mix ups.

    I write multiple scripts on one script pad, at the end though where is says refills I don’t know how to write refill for all or just put the number 1 down, does that mean all four meds can be refilled or just the last med. written on the list, or do I specify refill 1 for lithium, refill 1 for ambien…. How do you do that correctly. I write using Latin and always and . 0 after the dosage amount.

      It’s very similar.

      Instead of 1 tab by mouth, you would do 1 puff twice a day. Instead of # of pills, you would usually just do #1 or #3 for how many inhalers you want to give. Great question!

  20. JLAllen on May 29, 2014 at 11:30 pm

    Very good page. It would be good to see some more types of medications in the examples. Ones that would have helped when I was an intern include: insulin (esp the quantity dispensed), diabetic supplies (like BG strips), albuterol, steroid taper (the worst to write), Z-pak (actually the easiest to write), antibiotics (with a finite duration), topical meds, and sublingual nitroglycerin.

    And it might be good to point out that the frequency on PRN medications is typically the most frequent something is allowed. (A frequency of 4-6h makes sense on scheduled meds but not on PRNs).

I looked up the medications that we used and found this: For Cats, Ivermectin: 0.2-0.3 mg/kg SC q2wk 3-4 doses. It has been 10 years since I wrote a prescription of any kind, and I certainly don’t want to kill his cat, but after the amount per kg, but I’m uncertain about the SC q2wk 3-4 doses. I don’t want my brother or members of the family having Sarcoptic mange. Can you please help me decipher this? Luckily the dog stays on Ivermectin.

      Either your doctor wrote for a #120 quantity limit on the prescription or your insurance has a quantity limit on coverage. Most insurances will not cover for 2 tabs qid for a 30 day supply because that is a shit ton of pills so you get a 15 day supply instead.

    • Herbert on March 13, 2015 at 5:30 am

      Dexedrine is the tradename for dextroamphetamine sulfate.

      Adderall also comes in the form of dextroamphetamine sulfate although at different salt ratios.

      That explains why they look the same on your prescription label.

  39. Nicole Lloyd on January 26, 2015 at 11:31 am

    After medication is finish do U write discard meds. Jus curious!

    • Ryan Gray, MD on February 16, 2015 at 12:52 pm

      You can definitely write that. I typically don’t thought. If you are prescribing more than they need, maybe prescribe less.

    • Henry on March 13, 2015 at 5:53 am

      No Pharmacy would dispense 300 tablets of Ativan as that is way beyond any normal dosage. You would be instantly red flagged for forgery.

    How is this page not helping people to forge prescriptions? Especially the QA below. Sure, you need a DEA number for meds with high abuse potiential (Scheuled drugs), but those are easy to copy.

    Look at the meds people are asking how to write: AREN’T THEY ALL SCHEDULED PSYCHOTROPIC? Or are you trying to save the flagging system by helping fools self-medicate? Some of these people think there are drugs having names such as “Roxycodone”- — HELLO!!!

    BTW: I got here by Googling “buccal”. Now all I need is a stolen prescription pad.

      That’s true – some may be using it for nefarious acts, but it’s still worth it to help the medical students and others writing real scripts.

    I would like to know the correct way to write a prescription for oxycodonen30mg as needed for pain or 4-6hours for a month with 4refills

    • Henry on March 13, 2015 at 5:41 am

      oxycodone can not have refills. It is a Schedule II medication.

    Say that I want to write a prescription for 45 mg of Armour Thyroid, taken orally, daily. However, in order to make this amount I would need to prescribe one 30 mg and one 15 milligram taken at the same time, once daily. Is it possible for me to write one prescription specifying this or do I need to write to prescriptions, one for each amount, taken once daily?

    • Henry on March 13, 2015 at 5:49 am

      You have to write a prescription for each strength of the medication; however, you can write in the sig to take with the other strength so pharmacists are aware that you intend to have the patient take both strengths at the same time.

    The bit about quantity for a liquid being “one bottle” is outdated. You have to write out how many mLs you want to be dispensed.

  55. batu on May 19, 2015 at 10:57 am


    I wonder why you did not recommend the inclusion/wrting of diagnosis
    part in the prescription. As it is known, the pharmacist would be able to give
    more accurate advice and counselling to the patient if he/she knows what
    disease/condition the patient is suffering from. Furthermore, if the prescription
    contains diagnosis result (name of the disease), it will help the pharmacist to
    identify medication error from prescribing point of view (right medicine for
    the identified disease). Is that correct?

  58. MD student on June 1, 2015 at 9:06 pm

    It seems a lot of you are trying to forge prescriptions… good luck with that without a DEA number or prescription paper. Especially to those trying to get numerous refills on controlled substances.

    How would you write an RX for a medication that you need to take 1 tablet in the morning, 1 tablet in the evening and 1 tablet 1/2 way in between if needed. I have had three doctors write this three different ways.

    I was wondering since I got my prescription for ritalin filled the 22 and I called and said it hurting my stomach and only lasting a couple hours, so if I go to my psychiatrist on the 4th and she either ups my milligram or changes me to adderall. Will I be able to get it filled after I leave her office on th 4th?

    I got my prescription of ritalin filled the 22nd of October, I called my doctor and said it was giving me an upset stomach and wasnt lasting for more than 2 hours, so my doctor scheduled me another appointment for the 4th of November. If she ups my milligram of ritalin or changes me back to adderall can I get the prescription filled on the 4th when I leave the doctors office??

    I have a script with what looks like 3 or 4 letters (can’t really read them)… Closest guess is 8rly? and then a division symbol (÷ the line with 2 dots, in case the unicode doesn’t render right) and then the PO daily, as described above.

    I’m wondering what those 3 letters and that ÷ division code means?

    (I have medication name, strength, and #30 before that confusing part… Someone below noted there are some weird symbols for ‘sig’… but what is sig? xD)

    The scripts of today require a black light, watermarking and other things mixed in with the script. You old day script writers are out. if you try this method you are sure to get cuffed.

  73. Mike on December 24, 2017 at 10:10 am

    The old methods of writing prescriptions are gone. You will wind up in handcuffs that way. You need a lot more equipment fo avoid that. So good luck. The Mark below me is right.
