Most people are familiar with the experience of picking up a prescription at a pharmacy: the medication exists in a fixed dose, a fixed form, and a fixed formulation, manufactured by a pharmaceutical company in large batches. For the majority of patients with common conditions, this works well. But medicine is not one-size-fits-all, and for a meaningful number of patients, commercially available medications simply do not meet their needs. This is where compounding pharmacy comes in.
What Is a Compounding Pharmacy?
A compounding pharmacy is the practice of preparing customized medications tailored to the specific needs of an individual patient, based on a licensed practitioner's prescription. Rather than dispensing a pre-manufactured product, a compounding pharmacist combines, mixes, or alters pharmaceutical ingredients to create a formulation that does not exist commercially — or that exists commercially but in a form that does not suit the patient.
The practice of compounding is as old as pharmacy itself. Before the pharmaceutical industry industrialized drug manufacturing in the mid-twentieth century, virtually all medications were compounded. Today, compounding occupies a specialized but important role in the healthcare system, filling gaps that mass manufacturing cannot address.
In Canada, compounding is a controlled act within the scope of practice of licensed pharmacists and pharmacy technicians.1 It is regulated at the provincial level by pharmacy colleges — in Ontario, by the Ontario College of Pharmacists (OCP) — and guided by national standards set by the National Association of Pharmacy Regulatory Authorities (NAPRA).
Why Would a Patient Need a Compounded Medication?
There are several well-established clinical reasons why a physician might prescribe a compounded formulation rather than a commercially available product:
The required dose does not exist commercially. Pharmaceutical manufacturers produce medications in standard doses designed for the average adult patient. Pediatric patients, elderly patients with altered metabolism, and patients with unusual sensitivity often require doses that fall outside the commercial range. A compounding pharmacist can prepare the exact dose the physician specifies.
The patient cannot tolerate the commercial formulation. Many commercial medications contain inactive ingredients — dyes, preservatives, fillers, lactose, gluten — that some patients cannot tolerate due to allergies, sensitivities, or medical conditions. A compounding pharmacist can prepare the same active ingredient in a base free of the offending excipient.
The required delivery form does not exist. A patient who cannot swallow tablets may need a medication in liquid form. A patient with localized pain may benefit from a topical cream applied directly to the affected area rather than an oral tablet that affects the entire body. A patient requiring slow, sustained release may need a transdermal patch. Compounding makes these alternative delivery forms possible.
The commercial product has been discontinued. Pharmaceutical companies discontinue products for commercial reasons that have nothing to do with clinical need. When a medication that patients depend on is no longer manufactured, compounding pharmacies can often continue to provide it.
Combination therapy in a single preparation. A physician may determine that a patient would benefit from two or more active ingredients applied together — for example, a topical pain cream combining an NSAID, a muscle relaxant, and a local anaesthetic. Compounding allows these to be combined in a single preparation, improving convenience and adherence.
How Is Compounding Regulated in Canada?
Compounding in Canada is subject to a layered regulatory framework that ensures patient safety at every stage of preparation.
At the national level, NAPRA has published Model Standards for Pharmacy Compounding of Non-Sterile Preparations, which establish the minimum mandatory requirements for facilities, equipment, personnel training, quality assurance, and documentation.2 These standards use the language of "must" — they are not guidelines or best practices, but binding minimum requirements.
At the provincial level, each pharmacy college adopts and enforces these standards. In Ontario, the OCP has formally adopted the NAPRA Model Standards and requires all pharmacies engaged in non-sterile compounding to comply with them.1 The OCP conducts pharmacy assessments to verify compliance, and pharmacies that do not meet the standards are subject to regulatory action.
The standards distinguish between three levels of compounding complexity — Level A, Level B, and Level C — based on the risk profile of the preparation and the facilities required:
Restore Pharmaceuticals operates at Level A and Level B for non-sterile topical preparations, with full compliance with NAPRA and OCP standards.
What Is the Difference Between Compounding and Manufacturing?
This is a question regulators take seriously, and the distinction matters. Compounding is the preparation of a medication for a specific, identified patient based on a valid prescription from a licensed practitioner. Manufacturing is the large-scale production of medications for general sale, which is regulated under Health Canada's Food and Drugs Act and requires a Drug Identification Number (DIN).
A compounding pharmacy may not produce medications in bulk without a prescription, sell compounded preparations over the counter, or market compounded formulations as equivalent to commercially approved products. Each compounded preparation is prepared for a named patient, pursuant to a specific prescription, in a quantity appropriate for that patient's treatment course.
Health Canada's Policy on Manufacturing and Compounding Drug Products in Canada (POL-0051) sets out the boundary between these two activities and makes clear that compounding pharmacies that cross into manufacturing territory are subject to federal drug regulation.3

Frequently Asked Questions
Is a compounded medication the same as a generic drug?
No. A generic drug is a mass-manufactured copy of a brand-name drug, approved by Health Canada and assigned a Drug Identification Number. A compounded medication is prepared individually for a specific patient based on a prescription. The two are regulated completely differently.
Will my insurance cover compounded medications?
Coverage varies by plan. Many extended health benefit plans cover compounded medications when prescribed by a licensed physician. Contact your insurer to confirm your coverage before proceeding.
How do I know my compounded medication is safe?
Your compounded medication is prepared by a licensed pharmacist in a facility that meets NAPRA and OCP standards. The pharmacist verifies the prescription, selects pharmaceutical-grade ingredients, and follows documented compounding procedures. The same professional accountability that applies to any dispensed medication applies to compounded preparations.
Can I request a specific formulation from my doctor?
Yes. If you have had success with a particular base, concentration, or combination in the past, you can share that information with your prescribing physician and ask them to specify it in the prescription. Our pharmacists are also available to consult with prescribers on formulation options.
