Pharmacy Compounding Services: A Patient Guide
Understanding custom medication options • Educational overview
Compounding pharmacies prepare personalized medications based on a prescriber’s specific order. This guide describes common service areas where custom compounding is frequently used — from hormone therapy to veterinary care. We do not recommend treatments; every compounded prescription originates from your physician, nurse practitioner, dentist, or veterinarian.
The categories below describe areas in which licensed compounding pharmacies accept and prepare prescriptions. Active ingredients, strengths, dosage forms, and instructions always come from your prescriber. This information is for educational purposes and does not constitute medical advice.
Hormone therapy (BHRT) – bioidentical hormone replacement
Many prescribers order custom hormone formulations to match a patient’s individual needs. Compounded bioidentical hormones can be prepared in various forms: capsules, topical creams, sublingual troches, or suppositories. Common hormones include estradiol, progesterone, testosterone, and DHEA. Compounding allows precise strengths and combinations that are not commercially available.
If you and your prescriber decide that compounded hormone therapy is appropriate, the prescription will specify the exact ingredients, strength, and form. Many compounding pharmacies have dedicated resources for BHRT.
Pain management formulations
For chronic pain, some prescribers prefer topical preparations that deliver medication directly to the affected area. Compounded topical creams, gels, or ointments may combine multiple active ingredients (e.g., ketamine, gabapentin, amitriptyline, baclofen, diclofenac) at specific strengths. This approach can reduce systemic side effects compared to oral medications.
Low-Dose Naltrexone (LDN) is another common compounded prescription for neuropathic pain, fibromyalgia, and inflammatory conditions. All pain-related compounds are prepared exactly to the prescriber’s specifications.
Pediatric compounding
Children often need doses, forms, or flavours that are not available in manufactured products. A pediatrician or family physician may prescribe a flavoured liquid suspension, a low-strength capsule, or an allergen-free preparation. Compounding allows removal of common irritants like artificial dyes, preservatives, lactose, or gluten, and the addition of child-friendly flavours (grape, berry, bubblegum).
This service helps improve medication adherence and reduces stress for both children and caregivers.
Veterinary compounding
Pets often require medications in forms or flavours that are not commercially available. Veterinarians work with compounding pharmacies to prepare custom doses, palatable flavours (chicken, beef, tuna, bacon), and alternative delivery methods such as transdermal gels or chewable treats. Compounding makes it easier to administer medication to cats, dogs, and other companion animals.
Dermatology and topical preparations
Dermatologists and family physicians occasionally prescribe custom topical preparations — creams, ointments, gels, or lotions — for specific skin conditions. Compounding allows the prescriber to choose the exact active ingredients and concentrations, as well as a base that suits the patient’s skin type or sensitivities.
Hair loss formulations
Some prescribers write for custom topical formulations as part of a hair loss management plan. These preparations are prepared to the prescriber’s exact specifications. Patients interested in this option should discuss it with their family physician or dermatologist.
Allergen‑free and sensitivity‑specific preparations
Many manufactured medications contain inactive ingredients that some patients cannot tolerate: gluten, lactose, certain dyes, preservatives, or specific sugars/alcohols. When a prescriber identifies such a sensitivity, they can write a compounded prescription that uses only tolerated excipients. This is especially valuable for patients with multiple allergies or for pediatric populations.
Discontinued or hard‑to‑source medications
Drug shortages and discontinuations are increasingly common. If a manufacturer stops producing a medication that a patient relies on, a prescriber may determine whether the active pharmaceutical ingredient is still available for compounding. If so, a compounding pharmacy can prepare a similar formulation. Not all ingredients are available for compounding, but many are.
How a prescription reaches a compounding pharmacy
If your prescriber decides that a compounded medication is right for you, they will issue a prescription. Common ways to transmit the prescription:
- Fax – most prescribers can fax directly to the compounding pharmacy.
- Electronic prescription (eRx) – used by many clinics and pharmacies.
- Written prescription – you can bring a paper prescription to the pharmacy in person.
Once the pharmacy receives the prescription, a pharmacist will review it, confirm feasibility, and contact you with cost and timing. Many compounding pharmacies offer local delivery.

Common questions about compounding services
No. In Ontario, compounding pharmacies are regulated by the Ontario College of Pharmacists (OCP) with different accreditation levels (A, B, C). Level C is the highest standard, required for hazardous and complex preparations. Always ask about a pharmacy’s accreditation and quality practices.
Many private insurance plans provide coverage for compounded prescriptions, but benefits vary. Ask the pharmacy for a detailed receipt or check with your insurer directly.
Simple preparations may be ready in 24 hours. More complex or hazardous compounds may take 48–72 hours. The pharmacy will confirm timing when the prescription is received.
No. Compounding uses pharmaceutical-grade active ingredients. Some medications are not available in raw ingredient form, and some are not suitable for compounding due to stability or safety concerns. Your prescriber and the compounding pharmacist will determine feasibility.
