In Aotearoa New Zealand, a unit of the Ministry of Health, called Medsafe (the Medicines and Medical Devices Safety Authority) assesses the safety and effectiveness of medicines.

Once a medicine is approved for use by Medsafe, it's classified into 1 of the following groups:

  • prescription medicines
  • pharmacist-only medicines (also called ‘restricted medicines')
  • pharmacy-only medicines
  • general sale medicines.

Medicines that you can buy over-the-counter are classified as either pharmacy-only or general sale medicines. Where you can buy these medicines depends on their classification.

These medicines are only available when prescribed by a New Zealand healthcare provider on prescription. These medicines can’t be purchased over-the-counter without a valid New Zealand prescription.

Prescribers include New Zealand registered doctors, nurse practitioners, midwives, dentists, some optometrists, pharmacist prescribers and vets (who can prescribe medicines for animals).

An example of a prescription medicine is paracetamol + codeine tablets.


Controlled Drugs

Prescription medicines that can be misused are classified as controlled drugs. They are regulated strictly and are classified into class A, B or C according to their risk level.

The use, possession, and distribution of these medicines are tightly controlled to prevent misuse and protect public health. Depending on the class you’re prescribed, you may only get enough medicine to last 10 days or a month. Always check if there are repeats on the medicine label or your pharmacy receipt.

An example of a controlled drug is codeine tablets.

These can be supplied by a pharmacist in a pharmacy without a doctor’s prescription.

These medicines are kept in a restricted area. They're not available for self-selection from the pharmacy shelves, and you have to talk to a pharmacists before you can buy them.   

An example is Panadol Osteo® which has 665 mg of paracetamol in each tablet.


What happens if I want to buy a pharmacist-only medicine?

When supplying these medicines, pharmacists have to do these things:

  • Ask specific questions to make sure the medicine is safe and appropriate for you, for example they’ll ask if you take any other medicines and if you have any allergies or medical conditions. The pharmacist needs to confirm what the problem is and make sure the treatment is appropriate for you.
  • Provide you with information about the safe and correct use of the medicine
  • Record the sale of the medicine including your name and address.

Examples of some of the conditions which can be treated with pharmacist-only medicines are:

  • anaphylaxis
  • cold sores
  • stomach cramps
  • eye infections
  • fungal infections of the toe or fingernails
  • hay fever or rhinitis
  • haemorrhoids
  • migraine
  • mouth ulcers
  • muscle pain
  • nausea caused by migraine
  • skin problems such as itching, rashes, inflamed fungal infections
  • thrush of the mouth or vagina
  • travel sickness
  • warts.

Prescription medicines with an exemption

There’s a class of medicines that are prescription medicines that can be supplied by a pharmacist if they’ve completed extra training to supply these medicines, Examples include emergency contraception and some oral contraceptive pills.

All vaccines administered by trained vaccinator pharmacists come under this medicine classification.

Examples of some of the conditions which can be treated with prescription medicines with an exemption are:

  • erectile dysfunction
  • sleeping problems
  • urinary tract infections.

As with pharmacist-only medicines you need to have a consultation with a pharmacist. The pharmacist may offer to take you to private room before answering any questions. 

Your pharmacist can only supply these medicines using certain criteria. They may not be able to supply the medicine if you don’t fit the criteria, eg, if your blood pressure is outside the recommended range for safe supply of the medicine. They might advise you to see your doctor or nurse prescriber if they're unable to supply what you need.

Medicines that can be bought 'over a counter' in Aotearoa New Zealand are classified as pharmacy-only or general sale.


Pharmacy-only medicines

These medicines can only be sold from pharmacies. They are generally available for self-selection from the pharmacy shelves. Examples are paracetamol liquids for children or a packet of 100 paracetamol tablets.


General sale medicines

These are medicines that can be purchased from any retail store including a supermarket or petrol station. They are usually smaller pack sizes of medicines or medicines that are generally safe and don’t need special advice on how to use them safely. An example is a packet of 20 paracetamol tablets.
