A regular pharmacy dispenses medicines that have already been manufactured. A compounding pharmacy makes them. When a commercial product doesn’t suit your needs – wrong dose, wrong form, an ingredient you can’t tolerate – a compounding pharmacist formulates a medicine specifically for you, from scratch, on a valid prescription.
The Short Answer
| Regular Pharmacy | Compounding Pharmacy | |
|---|---|---|
| What they do | Dispense pre-made medicines | Formulate custom medicines per patient |
| Medicine source | Commercial manufacturers | Made in-house from individual ingredients sourced from TGA approved suppliers |
| Flexibility | Fixed dose, fixed form | Adjustable dose, form, and ingredients |
| Prescription required | Yes (for prescription medicines) | Yes but some items no |
| PBS / Medicare | Available where listed | Generally not covered |
| Turnaround | Immediate (in stock) | 24–72 hours depending on complexity |
| Best for | Standard treatments | Patients with specific clinical needs |
What a Regular Pharmacy Does Well
Your local chemist – whether it’s a Chemist Warehouse, a Priceline, or an independent pharmacy down the road – is built for speed and scale. They stock thousands of commercially approved medicines, they’re open long hours, and for the vast majority of prescriptions, they’re exactly what you need.
Walk in with a script for amoxicillin, atorvastatin, or a standard salbutamol inhaler, and you’ll leave with it in minutes. The medicine has been manufactured to strict quality standards, it’s been approved by the TGA, and it’s ready to go.
For everyday health needs, a regular pharmacy is fast, convenient, and often PBS-subsidised.
What a Compounding Pharmacy Does That a Regular One Can’t
Where commercial options run out, compounding begins.
A compounding pharmacist takes individual active pharmaceutical ingredients (APIs) and builds a medicine to a specific prescription – changing the dose, the delivery form, or the ingredient list based on what you actually need.
That might mean:
- Removing an allergen or intolerance trigger – lactose, gluten, artificial colours – from a medicine that would otherwise be the right treatment
- Changing the form – converting a tablet into a liquid suspension for a patient who can’t swallow, or a transdermal cream for someone whose gut can’t absorb oral medication effectively
- Adjusting the dose – especially for children or pets, where commercial doses are often too high, too low, or simply unavailable in paediatric form
- Flavouring a medicine – critical for paediatric patients and veterinary use, where palatability determines compliance
- Recreating a discontinued medicine – when a manufacturer stops producing a product, compounding can bridge the gap while your prescriber finds a longer-term solution
- Combining ingredients – some specialist treatment plans, particularly in hormone replacement therapy (HRT), call for formulations that don’t exist commercially
None of these are things you can walk into a regular chemist and request. They require a compounding pharmacy.
Do Regular Pharmacies Also Compound?
This comes up a lot.
Most pharmacies by their very nature can compound. They can make “simple” products like basic creams and liquids. However specialist compounders can complete “complex” compounding and make a very wide range of products and forms.
Specialist compounding pharmacies, like MyCompounder, focus on compounding as a core service rather than an add-on. This typically means very broad formulation capabilities for humans and pets, multiple dedicated compounding labs and specialist pharmacists whose primary expertise is in custom medicine preparation.
When You Need a Compounding Pharmacy
You likely need a compounding pharmacy if:
- Your doctor has written a prescription that specifies a compounded formulation
- You have a documented allergy or intolerance to an ingredient in the commercial version of a medicine you need
- The dose you need for your weight, age, or condition isn’t available commercially
- Your medicine has been discontinued and your prescriber wants to maintain continuity
- You’re treating a child and the standard dose or form isn’t appropriate
- You have a pet requiring medication in a form or dose that doesn’t exist commercially
- Your specialist has prescribed a hormone or integrative medicine preparation not available off the shelf
When a Regular Pharmacy Is Fine
Just as important: when you don’t need compounding.
If a commercially manufactured medicine exists that suits your dose, form, and ingredient needs – use it. Commercial medicines have been through rigorous TGA approval processes, they’re often PBS-subsidised, and they’re ready immediately. There’s no clinical benefit to compounding a medicine that’s available commercially and works for you.
Compounding exists to serve unmet clinical needs, not to replace commercial medicines that are already doing their job.
Cost, Turnaround, and Medicare: The Practical Differences
Cost
Compounded medicines are not listed on the Pharmaceutical Benefits Scheme (PBS). You pay the full cost of compounding, which varies based on the complexity of the formulation, the ingredients required, and the volume prepared. Some private health insurance extras policies include compounding cover – worth checking your policy.
Commercial medicines, where PBS-listed, benefit from government subsidy. For standard prescriptions, this can make a significant cost difference.
Turnaround
A regular pharmacy dispenses from stock. You wait minutes. A compounding pharmacy prepares your medicine after receiving your prescription. Depending on the formulation, turnaround is typically 24–72 hours, though complex preparations may take longer. At MyCompounder, we’ll give you a clear timeline when you submit your prescription.
Medicare
Medicare does not cover compounded medicines. Consultations with the prescribing doctor are a separate matter – Medicare may cover those depending on your circumstances – but the compounded medicine itself is not claimable under Medicare.
