Pharmacy Manager and co-owner, Orleans Compounding Community Pharmacy. Reviewing pharmacist for health and pet health content on orleansrx.ca.

Background

Dumitru Musteata is a registered pharmacist in Ontario and the pharmacy manager and co-owner of Orleans Compounding Community Pharmacy in Orléans, Ottawa. He came to Canada from Moldova, completed a pharmacy technician program in Calgary and worked as a technician at Calgary Foothills Hospital while preparing for Canadian pharmacist licensing, before qualifying and moving into community practice and ownership.

His day-to-day practice covers non-sterile compounding, veterinary dispensing, travel medicine and the minor ailments scope Ontario pharmacists prescribe under. The pharmacy is a Health Canada-designated Yellow Fever Vaccination Centre and compounds flavoured preparations for pets that will not take a commercial dosage form.

Why pharmacist review matters for pet supplements

Pet supplements are sold in Canada without the pre-market efficacy review that a drug goes through. Two products with the same front-of-label claim can differ by an order of magnitude in the amount of active ingredient they actually deliver. A pharmacist reads the same label the way they would read a drug monograph:

• Active ingredient and dose per kilogram — not the marketing claim on the front of the tub.
• Species suitability — a formula appropriate for a 30 kg dog is frequently wrong for a 4 kg cat, and some ingredients safe in dogs are not safe in cats.
• Interactions with prescribed medication — omega-3 with an NSAID, SAMe alongside certain drugs, probiotics timed against an antibiotic.
• Formulation and stability — enteric coating, refrigeration, CFU count at end of shelf life rather than at manufacture.
• Whether it is the right category at all — a supplement is not a substitute for a veterinary diagnosis, and sometimes the honest answer is to see the vet first.

How content on this site is reviewed

1. Drafted against manufacturer monographs, Canadian product labelling and published veterinary literature.
2. Reviewed by a licensed pharmacist for dosing accuracy, species suitability, interaction risk and claim language.
3. Dated. Every reviewed page carries the reviewing pharmacist's name, registration number and a review date.
4. Re-reviewed when a product monograph changes, a formulation is reformulated, or at least annually.

We do not publish claims that a supplement treats, cures or prevents a disease. Where evidence is weak or mixed, the page says so.
