Prof. Dr. Mehmet Şenoğlu — Brain, Nerve and Spine Surgery
One of the reactions I encounter most often in my office is this:
I prescribe a medication for a patient and say, “this will be given on a red prescription” — and the expression on their face changes instantly.
“A red prescription? Isn’t that for narcotics? Am I going to become addicted?”
I understand this concern very well. But it largely stems from a misunderstanding.
Let me state the main message of this article at the outset:
The color of a prescription does not indicate how “dangerous” a medication is, but how closely the state monitors it.
The color is not a label but a record-keeping system. And that system exists, in fact, to protect both you and the public.
In this article I will explain the five prescription colors one by one, summarize them in a comparison table, and answer the most frequently asked practical questions.
Why Do Prescription Colors Exist?
In Türkiye, prescriptions are color-coded according to the level of control the medication carries. This system is administered by the Turkish Medicines and Medical Devices Agency (TİTCK).
Its purposes are:
- To strengthen tracking and oversight while maintaining access to medication
- To prevent the misuse of medications that can cause dependence
- To stop these medications reaching those with addiction and traffickers
- To ensure that expensive and specialized products reach the right patient
A critical distinction: The color is determined by which control class the medication’s active substance falls into — narcotic, psychotropic, or subject to special control.
So the color is not a property of the medication but a record category. The same active substance can exist in different strengths and forms; which color it is subject to depends on its class in the TİTCK lists.
Comparison Table: The Five Colors at a Glance
| Color | Scope | Typical drug group | Level of control |
|---|---|---|---|
| White | All other prescription medications | Antibiotics, blood pressure and diabetes medications, most painkillers | Standard |
| Red | Narcotic medications | Strong opioid painkillers | Highest |
| Green | Psychotropic medications | Controlled medications that can affect mental processes and behavior | High |
| Orange | Blood clotting factors | Factor products used in the treatment of hemophilia | Special control |
| Purple | Blood products other than factors | Human albumin, immunoglobulins, Anti-D | Special control |
Now let us look at each in detail.
White (Normal) Prescription
Its scope: All prescription medications that do not fall into the other color groups.
The great majority of prescriptions you encounter in daily life are white: antibiotics, blood pressure medications, diabetes medications, stomach medications, most painkillers, and muscle relaxants.
Level of control: Standard. It does not require a special monitoring system.
For more detail: You can read our dedicated article on the scope and use of the white prescription and how it differs from the other types: What Is a White Prescription? Scope, Use, and Differences From Other Prescription Types
Red Prescription
Its scope: Medications containing a narcotic substance.
Level of control: The highest.
In Which Situations Is It Used?
As a spine and brain surgeon, I write this prescription most often in the following situations:
- Advanced cancer pain — particularly in spinal metastases
- Severe pain that does not respond to other treatments
- Certain postoperative pain situations
The medications used are strong painkillers of the opioid group.
Why Is It Monitored So Closely?
Because these medications:
- Can cause dependence
- Can lead to suppression of breathing when used incorrectly
- Carry a risk of misuse and trafficking
How does the system work? Red prescriptions are recorded electronically through the Colored Prescription System. The system automatically checks the following:
- The maximum daily dose
- The maximum number of packs
- Whether the patient already has the same or an equivalent medication
Indeed, as official notices state: If the patient already has the same medication or its equivalent, the system does not allow a new one to be added to the prescription.
Furthermore, the first copies of printed prescriptions dispensed by pharmacies are sent, together with monthly lists, to the Provincial Health Directorates.
What I Say to My Patients
I want to emphasize this section in particular:
A red prescription does not mean “you are going to become an addict.” It means “this medication is strong, and we will monitor it closely together.”
In a patient with genuine cancer pain, the likelihood of developing dependence on opioid treatment used at the correct dose and under medical supervision is not comparable to misuse on the street.
Do not endure your pain. Suffering out of fear of painkillers rests on no medical logic at all.
Green Prescription
Its scope: Controlled medications containing a psychotropic substance that can affect mental processes and behavior.
Level of control: High — but one step below the red prescription.
How Does It Differ From the Red Prescription?
The fundamental difference is this: the dependence-forming properties of medications on green prescriptions are lower than those on red prescriptions.
In Which Situations Will You Encounter It?
Medications within the scope of the green prescription are used across many fields:
- Anxiety and sleep disorders
- Certain treatments for nerve pain (neuropathic pain) ← the group most relevant to my own field
- Epilepsy and certain neurological conditions
- Attention deficit treatments
- Certain psychiatric treatments
An important note from the standpoint of spine surgery: Some of the medications used for nerve pain caused by lumbar and cervical disc herniation fall within the scope of the green prescription. This frequently surprises my patients — because they ask, “is this a psychiatric medication?”
The answer is no: These medications fall into this class because they affect the nervous system; it does not mean that you have a mental health problem.
The System Is the Same for Green Prescriptions
As with red prescriptions, green prescriptions are also recorded through the Colored Prescription System and pass through the same automatic checks.
Orange and Purple Prescriptions — First, a Warning
I need to issue an important warning about these two colors.
There are numerous sources online that contradict one another regarding orange and purple prescriptions. Some sites describe their scopes the other way around; some define the purple prescription as being for “cancer medications” — which is incorrect.
The information below is based on the official definitions in Ministry of Health circulars and pharmacists’ chamber notices.
Orange Prescription
Its scope: Blood clotting factors.
For whom? Predominantly patients with hemophilia.
Hemophilia is an inherited bleeding disorder in which the factors that enable blood to clot are deficient. These patients must receive the missing factor from outside — and these products are supplied on an orange prescription.
Why the special control? Because factor products:
- Are very expensive
- Are produced in limited quantities
- Must reach the right patient in the right amount, which is critically important
A detail worth knowing: Official regulations include a Hemophilia Follow-Up Card system for monitoring these patients. Special provisions also apply in emergency bleeding situations.
Purple Prescription
Its scope: Blood products other than factors.
Typical examples:
- Human albumin
- Immunoglobulins
- Anti-D immunoglobulin — used in cases of blood group incompatibility (Rh incompatibility)
An important exception worth knowing: As stated in official regulations, Anti-D immunoglobulin preparations used in blood group incompatibility can be dispensed by any pharmacy, whether or not that pharmacy has a quota. This provision exists because the timing is critical in pregnancy.
The Difference Between Orange and Purple — In One Sentence
Orange = blood clotting factors (hemophilia)
Purple = blood products other than factors (albumin, immunoglobulins, Anti-D)
How Does the Colored Prescription System Work?
Today the great majority of these prescriptions are issued electronically.
How does it work?
- The doctor creates the prescription through the Colored Prescription System
- Signs it with an electronic signature — which has the same legal validity as a wet signature
- The pharmacist accesses the prescription through the system using the electronic prescription number
- The system carries out the dose and pack checks automatically
When is a paper prescription used? Only in exceptional circumstances — if the system is not working for technical reasons, or at healthcare facilities not yet integrated into the system.
The practical meaning: Even if you do not have a paper prescription in hand, you can obtain your medication using your national ID number and your e-prescription number.
The Most Frequently Asked Practical Questions
“Can someone else collect my prescription?”
For colored prescriptions there are stricter rules on this. Identification is generally required. If a relative is collecting it, both your and their identity details may be needed. Check with your pharmacy in advance.
“How long is my prescription valid?”
The validity period varies according to the type of prescription and the regulations, and it can be updated over time. Get the most accurate information from your pharmacist. The general rule: do not sit on your prescription; have it processed as soon as possible after you receive it.
“The pharmacy didn’t have my medication — what should I do?”
The pharmacist is obliged to make every effort to find a medication that is not in stock. If it cannot be found at the wholesalers either, the situation is reported to the pharmacists’ chamber. This process is particularly relevant for products with limited stock, such as factor products.
“Can I take these medications abroad?”
This section is very important and is frequently overlooked.
When travelling abroad with medications on a red or green prescription:
- Always carry your prescription and/or your doctor’s report with you. This document shows that the medication genuinely is for your treatment.
- If you are travelling to Europe (the Schengen area), a Schengen certificate may be required for narcotic or psychotropic medications. This document is issued by authorized pharmacies.
- Every country’s rules are different. Some countries have very strict — even zero-tolerance — policies on controlled substances.
My advice: Consult both your doctor and the consulate of the country you are travelling to at least several weeks before your trip. This will prevent your holiday from ending at the airport.
On returning to Türkiye: In order for travellers to bring in medications for their personal treatment, they must be able to present to the customs authority a document (a report, a doctor’s letter, or a prescription) showing that they need to use these medications during their travel.
“Can I drive while using these medications?”
A significant proportion of medications on red and green prescriptions can cause drowsiness, reduced attention, and slowed reflexes.
Always ask your doctor about this. It is safest not to drive, particularly in the first days of treatment and when the dose is changed. This is a matter concerning the safety of both you and others.
“Can I share my prescription medication with someone else?”
Absolutely not. This is both medically dangerous and gives rise to legal liability. It applies in particular to medications on red and green prescriptions.
“My medication has run out but my appointment is a long way off”
With medications on colored prescriptions, stopping suddenly can be dangerous — particularly if they have been used for a long time.
What you should do: Do not wait until the very last day as your medication is running out. Contact your doctor or clinic in advance.
The Most Important Message of This Article
Receiving a colored prescription — particularly red or green — frequently creates a feeling of shame or stigma in patients.
I want to say this clearly:
The color of your prescription is not a judgment about you. It shows which record category your medication falls into — nothing more.
Just as a person with diabetes using insulin is not a “weakness,” neither is a patient with nerve pain using a medication on a green prescription, nor a patient with cancer pain receiving a painkiller on a red prescription.
What actually matters: That you use your medication at the dose your doctor has set, regularly, and under supervision.
Frequently Asked Questions
What determines prescription colors?
The control class of the medication’s active substance. Narcotic substances are red, psychotropic substances green, blood factors orange, blood products other than factors purple, and all remaining prescription medications fall within the scope of the white prescription. The color indicates not the strength or form of the medication but its level of control.
Does a red prescription mean “narcotics”?
Technically, the red prescription covers medications containing a narcotic substance. But this does not mean the medication is bad or forbidden — when used under medical supervision, for the right indication and at the right dose, these medications markedly improve quality of life, particularly in cancer pain. The color is a monitoring marker put in place to prevent misuse.
What is the fundamental difference between red and green prescriptions?
Both cover controlled medications that carry a risk of dependence. The fundamental difference is that the dependence-forming properties of medications on green prescriptions are lower. The red prescription represents the highest level of control.
What is the difference between orange and purple prescriptions?
The orange prescription is used for blood clotting factors (predominantly hemophilia treatment), and the purple prescription for blood products other than factors (human albumin, immunoglobulins, Anti-D). You will see these two colors frequently confused or described the wrong way round online — this is the official definition.
Why is my herniated disc medication given on a green prescription?
Some medications used in the treatment of nerve pain (neuropathic pain) fall into the psychotropic class because of their effects on the nervous system, and are within the scope of the green prescription. This does not mean you have been given a psychiatric diagnosis — it relates only to the medication’s control category.
I don’t have a paper prescription — can I still get my medication?
Most likely yes. Today colored prescriptions are predominantly issued electronically, and the pharmacist can access the system using your national ID number and the e-prescription number. Paper prescriptions are used only in exceptional circumstances.
Can I travel abroad with these medications?
You can, but it requires preparation. Always carry your prescription and/or your doctor’s report with you. If you are travelling to Europe, a Schengen certificate may be required for narcotic/psychotropic medications. Every country’s rules are different and some are very strict. Consult your doctor and the consulate of your destination country weeks before travelling.
Can I stop my colored-prescription medication on my own?
No. Particularly with red- and green-prescription medications taken over a long period, stopping suddenly can be dangerous and can cause withdrawal symptoms. The decision to reduce or stop must always be made by your doctor and carried out gradually.
Do these lists change?
Yes. Which prescription color a medication is subject to can be updated by regulation over time. A medication given today on a white prescription may be brought within the scope of the green prescription tomorrow. For the current position, it is best to consult your doctor, your pharmacist, and TİTCK’s official sources.
