Prescription and Non-Prescription Drugs: What's the Difference?
Have you ever stood in a pharmacy and wondered why some medicines are easily available on the shelves, while others need a prescription from your doctor?
This is because not all medicines are created equal. Some are designed to treat more serious conditions and need a doctor’s guidance to make sure they’re used safely. Others are made for non-acute everyday issues like headaches, colds, or mild allergies, and can be taken without professional supervision.
In this article, we will break down the difference between prescription and non-prescription (or OTC) drugs to help you understand
What is a prescription drug?
A prescription drug is a medication that you can only get with approval from a doctor or licensed healthcare provider. These drugs are used to treat specific medical conditions that require professional diagnosis, dosage control, and follow-up care. They aren’t sold openly because they can have stronger effects and potential side effects, or pose risks if taken incorrectly.
You’ll often see prescription drugs marked with the symbol “Rx.” This symbol comes from the Latin word recipe, meaning “to take.” It has been used for centuries in medical prescriptions and still appears on packaging and prescription labels to indicate that the medication must be prescribed.
What is a non-prescription drug?
Non-prescription drugs, also known as over-the-counter (OTC) medicines, are medications you can buy without a doctor’s prescription. They are considered safe and effective for public use when taken according to the instructions and are commonly used to manage minor health issues such as headaches, colds, allergies, or indigestion.
You’ll usually find OTC medicines on open shelves in pharmacies, supermarkets, and convenience stores. Because they’re intended for self-care, the packaging includes clear directions for use, proper dosage, and important safety warnings.
Key Differences Between Prescription and Non-Prescription Drugs
To understand the difference more clearly, here’s a simple comparison between the two:
1. Access
Prescription drugs require approval from a licensed healthcare professional to make sure they are used correctly. In contrast, non-prescription medicines can be purchased directly from pharmacies or retail stores, providing easy access for common and minor health concerns.
2. Treatment
Prescription drugs are used for managing more serious or long-term health conditions, things like infections, high blood pressure, or diabetes. These treatments often need a doctor’s diagnosis, proper dosage control, and follow-up. On the other hand, OTC medicines are made for quick relief of everyday issues such as headaches, colds, or indigestion. They are great for managing mild symptoms without the need to see a doctor.
3. Risk Level
The risk associated with prescription drugs is generally higher due to their potency and the conditions they address. It is crucial to understand these risks to ensure safe and effective use. Important risk factors include:
- Potential for serious side effects if not used properly
- Risk of interactions with other medications or underlying health conditions
- Need for precise dosing and regular medical supervision
OTC drugs typically have a lower risk profile when used according to instructions. However, misuse can still lead to health problems, such as:
- Mild side effects from overuse or incorrect use
- Allergic reactions in some individuals
- Possible interactions with other medications if not carefully managed
4. Supervision
Prescription medications require ongoing oversight by healthcare professionals. Doctors diagnose the condition, decide the right medicine and dosage, and monitor how well the treatment is working. This careful supervision helps minimize risks and ensures the medicine is effective. Non-prescription drugs, on the other hand, are designed for self-medication without direct medical supervision. However, it’s still important to follow the instructions and seek advice if symptoms don’t improve.
5. Storage
Prescription drugs sometimes need special storage conditions to keep them safe and effective. For example, some may require refrigeration or protection from sunlight, and pharmacies usually store them under these conditions. Non-prescription medicines are usually stored at room temperature and can be kept on open shelves in stores, making them convenient for consumers to access.
ATC Classification in Malaysia: How Medicines Are Categorised
In Malaysia, the ATC Classification System is widely used by healthcare professionals and regulatory bodies like the National Pharmaceutical Regulatory Agency (NPRA) to categorise both prescription and non-prescription (OTC) medicines. This system helps standardise how medicines are grouped, prescribed, dispensed, and monitored across public and private healthcare settings.
What is the ATC System?
Developed by the World Health Organization (WHO), the Anatomical Therapeutic Chemical (ATC) Classification System groups medicines according to:
- The organ or system they target (e.g., respiratory, digestive)
- Their therapeutic use (e.g., pain relief, allergy relief)
- Their pharmacological properties
- Their chemical characteristics
- The active substance used in the medicine
Each medicine is assigned a unique ATC code with five levels. For example:
Paracetamol (used for pain relief and fever):
ATC code: N02BE01
- N = Nervous system
- N02 = Analgesics
- N02B = Other analgesics and antipyretics
- N02BE = Anilides
- N02BE01 = Paracetamol
Cetirizine (used for allergies):
ATC code: R06AE07
- R = Respiratory system
- R06 = Antihistamines for systemic use
- R06A = Antihistamines, non-sedating
- R06AE = Piperazine derivativesR06AE07 = Cetirizine

Why Is It Used in Malaysia?
In Malaysia, the NPRA uses the ATC system as part of its drug registration and regulation process. This includes:
- Approving product indications (what it treats)
- Controlling which medicines can be sold OTC or need a prescription
- Assigning products to the right Poison Schedule under the Malaysian Poisons Act 1952
- Monitoring usage trends and public health data
For pharmacies and consumers, the ATC system helps:Categorise OTC products for easier selection (e.g., cold & flu, pain relief)
- Standardise product labels and drug information leaflets
- Improve safe self-medication practices
