Your vet handed you a prescription, and the chain pharmacy looked at you like you'd asked for something impossible. Maybe it was a precise dose for a 9-pound dog. Maybe your cat refuses every pill ever manufactured. Maybe the commercial version was discontinued months ago and nobody told you.
You're not alone — and you're not out of options.
At Marcum's Pharmacy in Kingsport, we've been solving exactly this kind of problem for over 60 years. The same pharmacists who compound custom medications for our human patients can do the same for your pet — with the same care, the same precision, and the same relationship you'd expect from a pharmacy that knows your name.
What Is a Veterinary Compounding Pharmacy?
A veterinary compounding pharmacy is a licensed pharmacy that creates customized medications for animals based on a valid prescription from a licensed veterinarian. Instead of relying on one-size-fits-all commercial formulations, a compounding pharmacist prepares the medication specifically for your pet — the right dose, the right form, and sometimes even the right flavor.
That distinction matters more than it might sound. Commercial pet medications are manufactured in fixed doses for average-sized animals. But animals — like people — come in all sizes, with all kinds of sensitivities and preferences. A 6-pound Chihuahua doesn't need the same dose as a 90-pound Labrador. A cat with a liver condition may react poorly to an ingredient in a standard tablet. A bird can't swallow a capsule.
Compounding fills those gaps. As prescribed by your veterinarian, a compounding pharmacist can adjust the dose, change the delivery form, remove a problem ingredient, or add a flavor that makes the whole thing easier on you and your pet.
Why Would a Vet Prescribe a Compounded Medication?
Veterinarians prescribe compounded medications for a handful of common, practical reasons:
- Non-standard dosing. Small breeds, exotic animals, and elderly pets often need doses that commercial products simply don't offer.
- Palatability. Some pets won't take medication no matter how creatively you hide it. A compounded chicken- or bacon-flavored liquid or chewable treat can make a real difference in whether treatment actually works.
- Alternative dosage forms. A cat that won't tolerate oral medication may do well with a transdermal gel applied to the inner ear. A horse may need a formulation that works with its size and physiology.
- Allergen or ingredient sensitivities. If your pet reacts to a dye, preservative, or filler in a commercial product, compounding can often remove the problem ingredient.
- Discontinued medications. When a manufacturer stops producing a medication, compounding may allow continued access — pursuant to a valid veterinary prescription.
If your vet has recommended a compounded medication, it's because they believe it's the right clinical fit for your specific animal.
Can a Regular Pharmacy Fill Veterinary Prescriptions?
Yes — a licensed compounding pharmacy like Marcum's can fill valid veterinary prescriptions. A standard retail pharmacy typically cannot, because they dispense commercially manufactured products in fixed doses and forms. Compounding requires specialized equipment, training, and state pharmacy board licensure to prepare customized formulations.
Marcum's is a full-service, independent compounding pharmacy licensed by the Tennessee Board of Pharmacy. We serve both human and veterinary patients, which means your pet's prescription gets the same pharmacist oversight and quality standards we apply to every compound we prepare — not a different tier of care.
Are Compounded Pet Medications Safe?
Compounded pet medications prepared by a licensed pharmacy, pursuant to a valid prescription from your veterinarian, are held to rigorous quality and safety standards. At Marcum's, every compounded formulation — for people or for pets — is prepared by a PharmD with careful attention to ingredient sourcing, precise measurement, and appropriate beyond-use dating.
It's worth being clear about one thing: compounded medications are not FDA-approved in the same way commercially manufactured drugs are. That's true for human compounds and veterinary compounds alike. What matters is that the pharmacy is licensed, the pharmacists are credentialed, and the preparation follows established compounding standards.
If you have questions about a specific medication or formulation for your pet, our pharmacists are here to walk you through it — not hand you a pamphlet and send you on your way.
Compounded medications are prepared pursuant to a valid prescription from a licensed veterinarian. Compounded drugs are not FDA-approved. Always consult your veterinarian before starting any new medication for your pet.

Why Marcum's — Not a Mail-Order Compounding Lab
There's no shortage of national mail-order compounding pharmacies. Some of them do fine work. But when something's not right — a question about your pet's formulation, a concern about how they're tolerating the medication, a change in your vet's prescription — a toll-free number and a shipping label aren't going to cut it.
At Marcum's, you can call and talk to a pharmacist. One you've probably already met. One who knows your family — and, now, your pet.
That's not a marketing line. It's the reason independent pharmacies like ours have survived for 60-plus years while chain pharmacies have opened and closed around us. Community accountability means something when it's your dog's medication on the line.
The Marcum family has been compounding for Kingsport patients since before mail-order compounding was even a concept. When you bring your pet's prescription to us, you're not a ticket number in a queue. You're a neighbor we want to help.
