Patient guide
What happens when the pharmacy cannot supply your prescription?
An out-of-stock notice tells you the pharmacy cannot get the product named on your prescription for now. The pharmacist cannot swap it for another product, so the next decision sits with your prescriber, and a different product can mean a new TGA application. General information, not medical or legal advice.
Last verified 7 October 2026 against the TGA and state health department pages. Rules change; check with your clinic and pharmacy before you rely on this.
The short answer
- An out-of-stock notice means the pharmacy cannot get the product named on your prescription at the moment. The notice does not cancel your prescription or the TGA approval behind it.
- A pharmacist cannot swap the product on a Schedule 8 prescription for another one. The TGA’s substitution instruments, which let pharmacists substitute during a shortage, cannot be made for Schedule 8 medicines.
- Any change of product is your Clinician’s decision and needs a new prescription from them.
- A Special Access Scheme Category B approval is granted for the product described in the application. A different product may need a new application, which the TGA processes in 2 to 5 days.
- Tell your clinic as soon as the notice arrives and say how many days of medicine you have left. Whether to space out, pause or stop what you have is a question for your Clinician.
Changing clinics
Moving your care from another clinic?
Our changing clinics page explains what to bring: your current prescription details and, if you have one, a treatment summary. A LeafLine Clinician reviews your history at a first consultation and decides what happens next.
At a glance
What each situation means for your prescription
The outcome depends on how long the product is unavailable and how close a replacement sits to what the TGA approved.
| Situation | What it means | What happens next | Source |
|---|---|---|---|
| New stock is expected soon | The pharmacy has run out before its next delivery, and the product is still being supplied in Australia | Your prescription and approval stay as they are. The pharmacy dispenses when stock arrives | TGA, Medicine shortages information for consumers, read 7 October 2026 |
| No date for new stock | The supplier cannot say when the product will return, or has stopped supplying it | The pharmacy cannot substitute. Your clinic is told, and your Clinician decides whether to change the product | TGA SAS guidance; Victorian Department of Health, April 2026 |
| Replacement fits the existing approval | Your Clinician chooses a product that matches what the approved application described | Your Clinician confirms the approval letter covers it and writes a new prescription | TGA SAS guidance, read 7 October 2026 |
| Replacement falls outside the approval | The replacement differs from what the approved application described | Your Clinician makes a new application to the TGA, waits for the approval letter, then writes the prescription | TGA, Special Access Scheme page, read 7 October 2026 |
| State or territory approval | Some states require their own approval for certain Schedule 8 prescribing | Your Clinician checks whether a change of product affects it | TGA SAS guidance, read 7 October 2026 |
Current at 7 October 2026. General information, not medical or legal advice. Sources, all read 7 October 2026 unless noted: TGA, Access to unapproved therapeutic goods for individual patients (last updated 3 December 2025); TGA, Special Access Scheme guidance for health practitioners (last updated 1 October 2024); TGA, Medicine shortages information for consumers (1 October 2025) and information for sponsors (30 September 2024); TGA, Serious Scarcity Substitution Instruments (1 October 2026); Victorian Department of Health, Dispensing medicines: requirements for pharmacists (April 2026). The Western Australian Department of Health site refused our connection on 7 October, so its guidance rests on our read of 1 September 2026. We could not read Queensland Health’s pharmacist pages, and we found no state page we could read on part supply of a Schedule 8 prescription, so this guide does not cover either. The TGA guidance does not set out a separate rule for changing products under an existing approval; the two approval rows apply its application requirements and standard conditions.

Three rules that shape what happens next
-
The pharmacy supplies what the prescription says
Victoria makes it an offence for a pharmacist to supply a Schedule 8 medicine contrary to the instructions on a prescription, outside exceptional circumstances. Western Australian guidance tells pharmacists to contact the prescriber when stock is unavailable before altering what is dispensed.
-
A change of product belongs to your Clinician
Choosing another product is a prescribing decision. Your Clinician weighs it against your history and what you have been taking, and writes a new prescription if they decide to change. The pharmacy can tell them what it is able to obtain, and the choice stays with the prescriber.
-
The TGA approval describes a product
A Category B application sets out the active ingredient, strength and dosage form, and the TGA’s standard conditions limit use to the manner described in the application. Your Clinician checks a proposed replacement against the approval letter before prescribing it.
The notice
What does an out-of-stock notice mean?
The notice is the pharmacy telling you, by phone, text or email, that it cannot fill the product named on your prescription at the moment. A useful notice names the product and says whether a date for new stock is known. If yours leaves either out, ask the pharmacy, and ask whether your prescriber has been told.
A notice can come from a short gap at the pharmacy or from a problem further up the supply chain. In the first case the pharmacy has run out ahead of its next delivery while the product is still being supplied in Australia. The TGA calls this a local supply disruption and says many resolve once the wholesaler and pharmacy receive new stock (TGA, read 7 October 2026). In the second case the company that supplies the product has paused or ended supply. The TGA states that sponsors are under no obligation to supply an unapproved therapeutic good (TGA, read 7 October 2026), so an approval that is still current does not guarantee the product stays available.
You will not usually be able to check which problem you have on the TGA's website. Its medicine shortage reports database covers reportable medicines, which the TGA lists as registered Schedule 4 and Schedule 8 medicines and certain non-prescription medicines (TGA, read 7 October 2026). An unapproved medicine is one that is not in the Australian Register of Therapeutic Goods, and local disruptions are left off the database as well. The pharmacy can ask its wholesaler or the supplier when stock is due, and that answer is the one your clinic needs.
Tell your clinic the day the notice arrives, and say how many days of medicine you have left.
Your Clinician
What your Clinician can do
The TGA places responsibility for sourcing an unapproved medicine on the prescriber, working with the dispensing pharmacy, and notes that an inability to source the product may require a change to the patient's treatment (TGA SAS guidance, read 7 October 2026). The pharmacy can tell your clinic what it is able to obtain, and your Clinician chooses between waiting and changing.
Your Clinician may decide to wait where the delay is short and you have enough medicine to cover it. Your prescription stays as written and the pharmacy dispenses when stock arrives. Your Clinician needs to know how many days you have left to judge this, so include that number when you contact the clinic.
Changing means your Clinician selects a replacement and writes a new prescription for it. They may want to speak with you first, because a different strength or dosage form can change how you take the medicine. Where a consultation is needed, it is booked as a review appointment at the prices on our fees page. Ask the clinic whether your change needs one.
The pharmacist's part is limited by law. The TGA's Serious Scarcity Substitution Instruments allow community pharmacists to substitute specific medicines without the prescriber's prior approval, and the TGA states it cannot make one for a controlled drug containing a Schedule 8 substance (TGA, last updated 1 October 2026). Victoria makes it an offence for a pharmacist to supply a Schedule 8 medicine contrary to the instructions on a prescription, outside exceptional circumstances in which the pharmacist must first take reasonable steps to obtain the prescriber's consent (Victorian Department of Health, April 2026).
The approval
Does a different product need a new TGA approval?
The answer turns on what your Clinician's application described. A Special Access Scheme Category B application sets out the product: its trade name if known, the sponsor, the active ingredient, strength, dosage form and route of administration, with the dose and expected duration. The TGA's standard conditions of approval include that the medicine is used only in the manner described in the application (TGA SAS guidance, read 7 October 2026).
A replacement that matches the approved description may be covered by the approval you already have. A replacement with a different active ingredient, strength or dosage form may sit outside it, and your Clinician then makes a new application before prescribing. The TGA guidance does not set out a separate rule for product changes, so this is a judgement your Clinician makes against the wording of the approval letter.
A new application adds time. The TGA states that Category B applications are processed in 2 to 5 days, and longer if it needs more information (TGA, read 7 October 2026). Some states also require their own approval for certain Schedule 8 prescribing, and the TGA says its approval does not override state or territory requirements. The approval guide explains what the letter contains and how long it runs, and the moving interstate guide covers the state layer.

What to do while you wait
Contact your clinic on the day the notice arrives. Give the date of the notice, the product it names, any date the pharmacy gave for new stock and the number of days of medicine you have left. Whether to space out what remains, pause or stop is a clinical question, so ask your Clinician and follow their instructions. The TGA's advice to patients in any shortage is to speak to their prescriber or pharmacist, and it does not give clinical advice itself (TGA, read 7 October 2026). If your prescription is close to its last repeat as well, the renewal guide sets out how far ahead to book a review. LeafLine patients can reach the team through the support page.
When the pharmacy cannot supply: common questions
What does an out-of-stock notice from the pharmacy mean?
It means the pharmacy cannot obtain the product named on your prescription at the moment. The notice does not cancel your prescription or the TGA approval behind it. If it gives no date for new stock, ask the pharmacy whether one is known and whether your prescriber has been told. This is general information, not medical or legal advice.
Can the pharmacist give me a different product instead?
A pharmacist cannot do that for a Schedule 8 prescription without your prescriber. The TGA’s Serious Scarcity Substitution Instruments let community pharmacists substitute specific medicines during a shortage, and the TGA states it cannot make one for a controlled drug containing a Schedule 8 substance. Victoria makes it an offence to supply contrary to the instructions on a prescription outside exceptional circumstances, and Western Australia’s guidance says the prescriber needs to supply a new prescription for an alternative product.
Does a change of product need a new TGA approval?
It depends on how far the replacement differs from what the approved application described. A Category B application sets out the active ingredient, strength and dosage form, and a standard condition of approval is that the medicine is used only in the manner described in the application. Your Clinician reads the replacement against the approval letter. If it falls outside, they apply again, and the TGA states that applications are processed in 2 to 5 days.
How will I find out what happens next?
Your clinic tells you once your Clinician has decided. The answer will be that the pharmacy has a date for new stock and the plan is to wait, that your Clinician has written a new prescription for a replacement, or that your Clinician wants to speak with you before changing anything. If you have heard nothing and your supply is getting short, contact the clinic and quote the date of the notice.
What should I do while I wait?
Tell your clinic the date of the notice, the product it names and how many days of medicine you have left. Whether to space out what you have, pause or stop is a clinical question, so put it to your Clinician and follow what they tell you. The TGA’s advice to patients during any shortage is to speak to their prescriber or pharmacist, and the TGA does not give clinical advice itself.
Will a change of product cost me a consultation?
A change may need a review consultation if your Clinician has to assess you before prescribing something different. LeafLine’s fees page lists $69 for a 20-minute repeat consultation and $59 for a shorter one. Ask the clinic whether your change needs a consultation before you book. The pharmacy sets the price of the medicine itself.
Can I look up the shortage on the TGA website?
You are unlikely to find it there. The TGA’s medicine shortage reports database covers reportable medicines, which the TGA lists as registered Schedule 4 and Schedule 8 medicines and certain non-prescription medicines. An unapproved medicine is one that is not in the Australian Register of Therapeutic Goods. The TGA also leaves local supply disruptions, where one pharmacy or area has run out, off the database. Your pharmacy and clinic are the better sources.
Can another pharmacy fill the prescription?
That depends on whether another pharmacy can obtain the product, so ask your clinic before you try. A pharmacy can dispense an unapproved medicine only if its supplier provides it, and the TGA places responsibility for sourcing the product on the prescriber, working with the dispensing pharmacy. Your clinic can find out what is obtainable and where.
Does the supplier have to keep supplying my medicine?
The supplier has no such duty. The TGA states that sponsors are under no obligation to supply an unapproved therapeutic good, and that an inability to source the product may require a change to the patient’s treatment. A product can be withdrawn while your approval is still current, which is why an approval letter does not guarantee stock.
What if my approval expires while I am waiting for stock?
A Category B approval runs for the period on the approval letter, and waiting for stock does not extend it. Tell your clinic if the date on your letter falls within the next month, so your Clinician can deal with the renewal and the stock problem together.
