Medication your pet will actually take
Cats spit out pills. Dogs find the one piece of cheese with a tablet in it. If your vet has prescribed something your pet refuses, or a dose that doesn't come in your animal's size, we can usually make a version that works.
The problem usually isn't the medication
It's the delivery. Commercial veterinary medications come in fixed strengths and dosage forms that do not always match an individual animal's size, species, or dosing needs. An animal that hides a pill for six hours and then spits it behind the couch isn't being stubborn; it's being a cat.
Compounding changes the form, the flavor, or the strength so the medicine actually gets into the animal.
What we can change
Tell us what's going wrong and there's usually a fix.
Your pet won't swallow a pill
Make it a flavored liquid, a chew, or a treat: chicken, beef, fish, and other flavors animals actually want.
You can't get near your cat with a pill
Some medications can be made as a transdermal gel you apply to the inside of the ear instead. Ask us whether your pet's medication is one of them.
The dose doesn't fit your animal's size
Compound the exact strength your veterinarian orders, rather than splitting a tablet made for a different-sized animal.
The medication is discontinued or on backorder
Often we can prepare it from the active ingredient once your vet writes for it.
Your pet reacts to an ingredient
Prepare it without the problem ingredient where the medication allows.
Not sure if yours is fixable? Ask us, or have your vet call. If it's compoundable and your veterinarian prescribes it, there's a good chance we can help.
What we compound for animals
Working from your veterinarian's prescription, the categories we prepare most often:
Gastrointestinal
Appetite, nausea, and digestive medications, often as flavored liquids.
Cardiovascular and renal
Long-term daily medications where getting the dose right matters and compliance is everything.
Antimicrobial and antifungal
Including preparations for skin and ear conditions.
Thyroid and hormone regulation
Including trilostane for dogs, prepared to your vet's specified strength.
Behavioral
Anxiety and situational medications, in forms that don't create a fight at dosing time.
Neurological and anti-seizure
Including compounded gabapentin.
Something not on this list? Ask. This is what comes through our door most, not the limit of what we make.
Call us, or have your vet call
If you know what your pet won't take, we can usually tell you what's possible before the next appointment.
Your veterinarian writes the prescription
Compounded animal medications need a prescription, the same as human ones. We'll talk through strength, form, and flavor options with your vet directly.
We prepare it for your animal
Typically 48 to 72 hours, depending on the preparation. We'll tell you what to expect when the prescription comes in.
Pick it up, or we'll deliver locally
Curbside pickup and local delivery are both available.
For veterinary practices
If you're prescribing compounded medications for your patients, here's what working with us looks like.
Prefer to fax or call? Fax 864-520-1505, call 864-520-1550, or email info@greenhillrx.com.
We prepare to your specification
Strength, dosage form, flavor, and vehicle: you tell us what the patient needs and we prepare that, rather than substituting from a catalog.
A pharmacist takes your call
Questions about a preparation, a strength, or whether something is compoundable get answered by a pharmacist, not routed to a queue.
We're non-sterile, and we'll say so up front
We compound non-sterile preparations only: oral liquids, capsules, transdermals, and topicals. We don't prepare sterile injectables. If a patient needs one, tell us anyway, we can often still take the rest of the case.
Turnaround is typically 48 to 72 hours
And we'll tell you when it isn't.

Pet owners call us about this every day
“My animal won't take this” is the reason nearly every time. If you're not sure whether something can be made differently, that's the call to make.
