Unrestricted S8 substances

Prescribers must notify Medicines and Poisons of the supply of unrestricted S8 substances such as morphine and pethidine if supply exceeds eight weeks, or if other circumstances arise that are in the Code of Practice.

Prescribers also need a special authorisation if they want to prescribe for more than an approved number of patients.

Compliance is the responsibility of the prescriber, and pharmacists are not expected to routinely monitor these matters as a part of dispensing.

However pharmacists may contact Medicines and Poisons if they have particular queries or concerns.

Restricted S8 substances

These categories of S8 substances have the following supply restrictions applied to them.


Stimulants include dexamfetamine, lisdexamfetamine and methylphenidate.

General medical practitioners and nurse practitioners can co-prescribe in conjunction with a specialist paediatrician, psychiatrist, neurologist, physician or registrar in training in one of these disciplines.

Prescribers are required to obtain authorisation before prescribing these substances.

Pharmacists are not required to check whether a prescriber has obtained authorisation, however they may contact Medicines and Poisons with queries or concerns.

Opioid substitution

This includes buprenorphine, buprenorphine/naloxone and methadone 5mg/mL liquid.

Medical practitioners and nurse practitioners providing opioid substitution need to be specially trained and accredited by the Chief Health Officer.

Medicines and Poisons can provide information on whether prescribers are accredited.
