A compounding pharmacy prepares medicines that are tailored to an individual patient’s needs. Instead of relying only on standard, mass-produced products, a pharmacist can create a formulation in a specific strength, dosage form, or ingredient profile when that is clinically appropriate.

What “compounding” actually means
Compounding is the pharmacist-led preparation of a medicine according to a prescriber’s instructions and a patient’s requirements. It may involve combining ingredients, adjusting a dose strength, or changing how the medicine is delivered. The goal is not to create a “stronger” medicine, but to make a prescribed therapy workable for a particular person when standard options are unsuitable.
Common compounding tasks include:
- Preparing a dose strength that is not commercially available.
- Changing a medicine into a different form, such as a liquid for someone who cannot swallow tablets.
- Making an allergy-friendly version by excluding certain excipients, dyes, or flavours, where appropriate.
- Creating a measured topical preparation, such as a cream or gel, when a prescriber requests a specific concentration.
Compounding is done in response to a clinical decision. It is typically based on a prescription and should be supported by proper labelling, instructions, and counselling.
Situations where compounding is commonly used
Compounding is often considered when a patient’s needs do not match what is available off the shelf.
One example is dose individualisation. Children, older adults, and people with specific dose requirements may need a strength that is hard to achieve using standard tablets without splitting or complex calculations.
Another common situation is medication intolerance or sensitivity. Some people react to non-active ingredients like certain dyes, preservatives, or fillers. When clinically appropriate, a prescriber may request a formulation that avoids particular ingredients.
Compounding can also help when a dosage form is a barrier. If a person struggles with swallowing, has feeding tubes, or needs a topical option rather than an oral one, a pharmacist may be able to prepare a suitable form that supports consistent use.
Finally, compounding may be used when a commercially produced product is temporarily unavailable and a prescriber decides an alternative formulation is necessary to maintain treatment continuity.
How compounded medicines differ from standard products
Standard medicines are manufactured at scale with fixed strengths and dosage forms, and they are supported by product-specific testing and regulatory pathways. Compounded medicines, by contrast, are prepared for an individual patient in response to a prescription, using professional standards and quality processes within the pharmacy setting.
Because compounded medicines are customised, the instructions, storage requirements, and shelf life can differ from what people are used to with packaged products. For example, a compounded liquid may have different stability considerations than a commercial tablet, which affects how it is stored and how long it remains suitable to use.
This is also why communication matters. The prescriber, the pharmacist, and the patient all need to be aligned on the exact formulation, the directions, and any monitoring needed.
What to expect from the compounding process
While each case is different, many compounding prescriptions follow a similar pathway.
First, the pharmacist checks the prescription details and clarifies anything that affects safety or accuracy, such as the intended dose, the formulation type, and any relevant allergies.
Next comes formulation selection and preparation. This may involve measuring active ingredients, selecting an appropriate base (for a cream, gel, or capsule), and using equipment designed to improve consistency and uniformity.
After preparation, the medicine is labelled with directions, storage instructions, and other required information. A key part of the process is counselling, which should cover how to take or apply the medicine, what to do if a dose is missed, and any practical handling tips.
If you are unsure about anything, this is the moment to ask. The usability of a compounded medicine often depends on small details like measuring devices for liquids, application amounts for topicals, or timing around food.
Practical questions to ask before you start
A few targeted questions can prevent confusion later:
- What is the exact dose and how should it be measured?
- Are there special storage requirements such as refrigeration or protection from heat?
- What is the expiry date, and what signs mean it should not be used?
- Will the medicine look or feel different from a commercial version?
- What should you do if symptoms change or if you suspect a side effect?
- Are there interactions with other medicines, supplements, or topical products?
These questions are not about second-guessing the prescription. They are about ensuring you can use the medicine correctly and consistently.
Making the most of a compounding prescription
Compounded medicines work best when you treat them like a carefully tailored tool. Follow the directions exactly, store them as instructed, and keep the label information accessible. If anything about the formulation seems off, such as unexpected separation in a liquid or changes in texture, contact your pharmacist promptly rather than adjusting the dose yourself.
It can also help to keep a simple note of when you started the medicine and how it is going, especially if the prescriber plans follow-up adjustments. That feedback loop is often part of why compounding is chosen in the first place: it allows treatment to be fitted to the patient, not the other way around.
