Urgent: you have run out and cannot reach your prescriber
This is the most common message we receive: "I have run out of my medication and have not been able to get in contact with her." The doctor may have left the clinic, the telehealth service may be slow to respond, or the script may simply have run out of repeats. Whatever the reason, you do not need to wait for the original prescriber. Any Australian doctor who is satisfied that continuing is appropriate can write a new script.
How quickly a new script can be issued
- A telehealth GP consult can often be booked for the same or next day. The consult itself is usually short for a straightforward continuation if you have your history ready.
- If the doctor agrees to continue, an eScript token is sent to your phone by SMS or email, typically during or shortly after the consult. You take that token to any pharmacy.
- The real delay is usually pharmacy stock, not the script. Ring the pharmacy before the consult and ask whether they have your strength in stock or how long an order takes. Our Mounjaro Australia guide covers supply in more detail.
What to have ready for the new doctor
A new prescriber is not copying the old script. They are making their own clinical decision and they will do that faster and more confidently if you give them evidence rather than memory. Gather as much of the following as you can:
- Your previous scripts, or the dispensing labels and boxes from your last pens. The label shows the prescriber, the strength and the date dispensed.
- Your current dose, how many weeks you have been on that dose, and the date of your last injection.
- Your weight history: starting weight, current weight and roughly when each dose change happened. A photo of a tracking app is fine.
- Side effects you have had, especially anything that made you pause or skip doses.
- Other medications, medical conditions, and any recent blood tests. Diabetes, thyroid history, pancreatitis, gallbladder problems and pregnancy plans all matter.
- If you cannot find your scripts, ask your usual pharmacy to print your dispensing history, or check My Health Record if you have one. Both are quick and free.
How long a gap is acceptable before the dose may be stepped down
There is no single rule, and your doctor's judgement decides. In practice the pattern looks like this:
- A few days late on a weekly dose is usually just a late dose. The product information gives guidance on a single missed dose; follow it or ask your pharmacist.
- A gap of a week or two is generally handled by resuming the same dose, provided you were tolerating it well.
- Once you have been off for several weeks, particularly at the higher strengths, many doctors prefer to restart one or two steps lower and titrate back up. The reason is simple: tolerance to the nausea, vomiting and bowel changes fades while you are off the medicine, and jumping straight back to a high dose is how people end up very unwell.
- If you are asked to step down, it is not a setback in your treatment plan, it is a tolerability decision. Most people are back at their previous dose within a few weeks.
Do not fill the gap with leftover pens from someone else, with product bought online, or with a different GLP-1 medicine you happen to have at home. Tell the new doctor honestly how long you have been off; they will plan around it.
Arriving in Australia on an overseas prescription
Three versions of this come up constantly: "travelling to Australia for two years, currently taking Mounjaro"; "prescribed tirzepatide for a 12 week course but only able to bring a one month supply"; and a visitor on a compounded GLP-1 product taken mainly for food noise. The rules that apply to all three are:
- Overseas scripts cannot be dispensed here. An Australian pharmacy can only dispense against a prescription written by an Australian-registered prescriber. A script from the UK, US, Europe, Asia or anywhere else is useful as evidence of your treatment, but it will not get you medication over the counter.
- Mounjaro is the only tirzepatide product approved in Australia. If you were on a differently branded tirzepatide overseas, or a compounded version, you will be moved onto Mounjaro. The active ingredient is the same; the pen device and strengths may look different from what you are used to.
- Compounded GLP-1 products are not a realistic continuation option. Australian rules on compounding these medicines have tightened substantially. Expect to be transitioned to the approved branded product, and expect the doctor to ask what strength you were actually taking, because compounded products are often labelled in ways that do not map cleanly to the registered doses.
- A local doctor must take over prescribing. This is a new patient consult, not a rubber stamp. Bring your overseas script, the packaging, your dosing history and weight history exactly as described in the section above.
Practical steps if you are still planning your trip
- Check the TGA's current guidance on bringing personal medication into Australia before you fly. Carry the medicine in its original packaging with your prescription and a letter from your doctor. Keep it in your hand luggage with cold packs if the journey is long.
- Book an Australian telehealth or GP appointment for your first week here rather than your last week of supply. Pharmacy ordering can take time and you want overlap, not a gap.
- If you are on a visa that does not include Medicare, you will pay the full consult fee as well as the full medicine price. Check whether your travel or health insurance covers either.
- If you are mid-way through a planned 12 week course, tell the Australian doctor the intended end point. They may continue, extend or stop it based on their own assessment, and they are entitled to do that.
- For a two year stay, think about finding a regular GP rather than relying on one-off telehealth consults. Continuity makes dose changes, blood tests and eventual tapering far easier.
Your current service will not increase your dose
A frequent frustration: "I am currently getting 2.5 mg through an online script service, I want to go to 5 mg but they will not prescribe it." It helps to understand why this happens before deciding what to do.
Why some services cap doses
- Internal protocols. Many high-volume telehealth services run on fixed pathways. Some only initiate treatment and refer dose changes elsewhere; some have a maximum strength they will prescribe; some require a review consult or a weight check before each step.
- Prescriber scope. The person reviewing your request may be working within limits set by the service, not making a free clinical judgement about you.
- Clinical caution. Occasionally the refusal is genuinely about you: side effects you reported, a weight that is already close to a healthy range, a condition that needs checking first, or too short a time on the current dose.
None of this is a legal cap. There is no rule that stops a different AHPRA-registered doctor from assessing you and, if they agree it is appropriate, prescribing the next strength. You are allowed to seek a second opinion, and you are allowed to change prescribers.
What a new prescriber will weigh up
- How long you have been on the current dose. The usual pattern is a minimum of four weeks per step, and many doctors want to see that you have tolerated it comfortably before moving up.
- Whether you are still losing weight on the current dose. If you are, there is often no reason to escalate yet. If progress has clearly plateaued, escalation becomes more reasonable.
- Weight-related conditions. Sleep apnoea is a good example. If you have diagnosed obstructive sleep apnoea, high blood pressure, prediabetes or joint problems that are improving with weight loss, that strengthens the case for continuing and titrating because the treatment is doing more than changing a number on the scales. Bring any sleep study results or specialist letters.
- Distance from goal weight. If you are already near a healthy weight, a careful doctor may decline to escalate and instead talk about holding your current dose, or even stepping down to a maintenance dose. That is not obstruction, it is the right conversation to have, and the section below covers it.
- Side effects. Persistent vomiting, severe reflux, dizziness or signs of gallbladder trouble will pause any escalation regardless of who is prescribing.
Be upfront with the new doctor that your previous service declined to increase the dose and, if you know it, why. Hiding that tends to come out later and it damages trust. Most doctors respond well to "they only prescribe up to this strength" and badly to discovering it afterwards.
Switching to a local GP for a low dose maintenance script
"I have lost 15 kg and I am looking to maintain." At this stage many people are paying a subscription or per-consult fee to an interstate telehealth service that made sense when they needed frequent titration support but makes much less sense when all they need is the same low dose every month. A regular GP is often the better fit, and the switch is straightforward.
What affects the cost of switching
- The consult fee. A standard GP appointment, whether bulk billed or privately billed, is usually a different cost structure from a telehealth subscription. Ask the practice what they charge and whether a Medicare rebate applies to you.
- Telehealth rebate conditions. Medicare rebates for GP telehealth have conditions, and in many cases require an existing relationship with the practice. If you want ongoing phone or video consults, ask whether a first face-to-face visit is needed to unlock that.
- The medicine itself. Unless you meet current PBS criteria for type 2 diabetes, you pay the private price for Mounjaro whoever prescribes it. Changing prescriber does not change the price at the pharmacy. See Mounjaro Cost Australia.
- Repeats. Ask the GP whether they are comfortable writing repeats for a stable maintenance dose so you are not booking a consult every four weeks.
How to approach the first GP visit
- Say plainly what you want: to continue your current dose for weight maintenance under their care, with periodic review.
- Bring the same records listed in the first section, plus a summary of your result: starting weight, current weight, dose history and how long you have been stable.
- Expect a discussion about how long maintenance should continue, what happens if weight creeps back, and whether a lower strength would hold the result. Some doctors prefer to step down gradually and watch; others keep the dose that achieved the result. Both are legitimate approaches.
- Not every GP prescribes GLP-1 medicines for weight management. If yours declines, ask whether anyone else in the practice does, or use the form below and we will match you with one who does.
Restarting Mounjaro after a break
People stop for all sorts of reasons: supply shortages, cost, pregnancy, surgery, side effects, or simply reaching a goal and wanting to see how they go without it. Restarting is common and a new prescriber can handle it, but it is treated as a fresh assessment rather than a continuation.
- Expect to restart low. After a break of more than a few weeks, most doctors go back to the starting strength or close to it and titrate again. Your body no longer has the gradual adaptation that protected you from side effects.
- Be honest about why you stopped. If it was side effects, the doctor may titrate more slowly or discuss alternatives such as semaglutide. If it was cost, say so; it affects how aggressively they titrate and whether a lower maintenance target makes sense.
- Bring your old weight data and your current weight. Regain is normal after stopping and is not a reason for embarrassment; it is useful information about how your body responds.
- Check for anything that has changed: new medications, new diagnoses, pregnancy plans, recent surgery. These can change whether restarting is appropriate.
- Do not use old pens that have been out of the fridge, past their in-use period or past expiry. Ask the pharmacist if you are unsure.
Common mistakes when changing prescribers
- Waiting until the last pen is used. Start looking for a new prescriber when you have two or three doses left. Pharmacy ordering times are the usual bottleneck.
- Turning up with no records. "I think I was on 7.5" is not enough for a doctor who has never met you. Labels, boxes, dispensing history or a tracking app screenshot change the conversation entirely.
- Assuming an overseas script will be honoured. It will not be dispensed. Treat it as evidence for the new doctor, nothing more.
- Jumping straight back to a high dose after a long gap. This is the most common cause of severe side effects we hear about from people who self-managed a restart.
- Buying from unregulated sources to bridge the gap. Counterfeit and mislabelled products exist. A week off treatment is far safer than an unknown product.
- Not telling the new prescriber about the old one. Doctors can see dispensing history through My Health Record and prescription monitoring systems. Be straightforward about who prescribed before and why you are changing.
- Running two prescribers at once. Getting scripts from two services simultaneously is a quick way to have both of them stop prescribing. Finish with one before starting with another, or tell both.
Frequently asked questions
I have run out of Mounjaro and my doctor is not answering. Can another doctor just give me a script?
Yes, if they assess you and agree that continuing is appropriate. Any AHPRA-registered doctor can prescribe. Book a telehealth or GP consult, bring your previous scripts or dispensing labels, your current dose, the date of your last injection and your weight history. If the doctor agrees, an eScript token is usually sent to your phone the same day. Check pharmacy stock before the consult.
How long can I go without Mounjaro before I have to start again from the beginning?
There is no fixed cut-off and it is your doctor's call. A late dose or a gap of a week or two is usually just resumed. After several weeks off, especially at the higher strengths, many doctors prefer to restart one or two steps lower and titrate back up, because side effect tolerance fades while you are off the medicine.
I am moving to Australia for two years and I am on Mounjaro. Can I use my prescription from home?
Not at a pharmacy. Australian pharmacies only dispense against scripts written by Australian-registered prescribers. Bring your overseas script and packaging as evidence, book an Australian doctor for your first week here, and let them take over prescribing. Check the TGA's current traveller guidance on carrying personal medication before you fly.
I was prescribed tirzepatide overseas but could only bring one month of a 12 week course. What do I do?
See an Australian doctor before your supply runs out. Mounjaro is the only tirzepatide product approved here, so you will be moved onto it. The doctor will decide whether to continue, extend or stop the course based on their own assessment, so bring your dosing records and explain the original plan.
I am visiting and I take a compounded GLP-1 for food noise. Can I keep getting it in Australia?
Not in the same form. Australian rules on compounding these medicines have tightened substantially, so expect an Australian doctor to assess you for the approved branded product instead. Bring whatever labelling you have, because compounded strengths often do not map cleanly to the registered doses and the doctor will need to work out an equivalent starting point.
My online script service will only prescribe 2.5 mg. How do I get 5 mg?
Many services have internal protocols that limit doses or require reviews; that is a business or clinical policy, not a legal cap. A different AHPRA-registered doctor can assess you and prescribe the next strength if they consider it appropriate. They will want to know how long you have been on 2.5 mg, how you tolerated it, whether weight loss has plateaued, and about weight-related conditions such as sleep apnoea. Tell them the previous service declined and why.
Will a doctor refuse to increase my dose if I am close to my goal weight?
Possibly, and it is a reasonable position. If you are near a healthy weight, the discussion often shifts from escalation to maintenance: holding the current dose or stepping down while watching for regain. If you have conditions that are still improving, such as sleep apnoea or blood pressure, say so; that is relevant to the decision.
I have lost 15 kg and just want a maintenance dose. Can my regular GP take over from my telehealth service?
Usually yes, if the GP is comfortable prescribing GLP-1 medicines for weight management. Bring your dose and weight history, explain that you want to maintain, and ask about repeats and periodic review. The medicine price is the same whoever prescribes it; the saving is in consult fees and subscription costs.
Does changing prescriber change what I pay for Mounjaro at the pharmacy?
No. Unless you meet current PBS criteria for type 2 diabetes, you pay the private price regardless of who writes the script. What changes is what you pay the prescriber. See Mounjaro Cost Australia.
Can the pharmacist give me an emergency supply without a script?
Do not count on it. Pharmacist emergency supply provisions are narrow and vary by state. Ask your pharmacist, but the reliable path is a telehealth consult and an eScript, which can often be done the same day.
Should I just switch to Ozempic or Wegovy if I cannot get Mounjaro continued?
That is a conversation for the new prescriber. Semaglutide is a different medicine with its own titration schedule; you do not simply swap at an equivalent dose. See Mounjaro vs Ozempic and Mounjaro vs Wegovy for background before the consult.
Need a prescriber who will continue your current dose?
Tell us where you are up to: your current dose, how long you have been on it, when your last injection was, and whether you have run out, are arriving from overseas, have been refused a dose increase, or want a local GP for maintenance. We will connect you with an AHPRA-registered prescriber pathway that handles continuation patients and can point you to a pharmacy that will tell you about stock. We do not sell medication and we do not issue scripts; the doctor makes every clinical decision.
Tell us what you need and we'll match you with a clinic that will contact you directly. Free, no obligation.

Key takeaways
- Any AHPRA-registered Australian doctor can take over your Mounjaro prescribing; you do not have to wait for an unreachable prescriber.
- A telehealth consult can usually produce an eScript the same day. Pharmacy stock is the real bottleneck, so ring ahead.
- Bring evidence: previous scripts or labels, current dose, date of last injection, weight history, side effects and medications.
- Short gaps are usually resumed at the same dose; after several weeks off, expect to step down and titrate back up.
- Overseas scripts cannot be dispensed here, Mounjaro is the only approved tirzepatide product, and compounded GLP-1 products are not a continuation option.
- Dose caps at online services are policy, not law. A different prescriber can assess an increase, and sleep apnoea or nearness to goal weight will shape that decision.
- For maintenance after a good result, a local GP is often cheaper and simpler than an interstate subscription service. The medicine price does not change.
