What Is Veterinary Compounding?

Veterinary compounding is the process of preparing a medication specifically for one animal. Instead of using a pill made for an average human or an average-sized dog, a pharmacist starts with pharmaceutical ingredients and makes the medicine in the strength, form and flavor that fits your pet.

Most people discover pet compounding the hard way: after a week of hiding pills in cheese, wrapping a cat in a towel, or cutting tiny tablets into quarters that never seem to split evenly. A compounding pharmacy for pets solves those problems at the source. Your veterinarian still decides what your pet needs. We make it easier to give.

Compounding is especially helpful when:

  • Your pet won’t take pills. Cats in particular are famous for it. A transdermal gel or a flavored treat can replace the daily struggle.
  • The dose doesn’t exist commercially. A 4 pound cat and a 120 pound dog may need the same drug at very different strengths.
  • Your pet needs a liquid. Small animals, senior pets, and pets with trouble swallowing often do better with a measured oral suspension.
  • A medication has been discontinued or is on backorder. We can often prepare the drug your vet needs when the commercial version is hard to get.
  • Your pet has allergies or sensitivities. Compounding allows us to leave out dyes, fillers or other ingredients your pet can’t tolerate.

A quick note on regulation: compounded medications are prepared by a licensed pharmacy for an individual patient, and they are not FDA-approved products. That’s why every compound we make requires a written prescription from a veterinarian who knows your pet.

Easier Ways to Give Your Pet Medicine

The biggest reason pet owners come to us is simple: their animal won’t take its medication. We offer several dosage forms so your veterinarian can choose the one that fits your pet’s personality and needs.

Transdermal Gels (Rub-On Medication)

Transdermal medication is applied to the skin, usually the hairless inner part of a cat’s ear, and absorbed from there. No pills, no forcing the mouth open, no spit-out tablets under the couch. Our transdermal gels are dispensed in a metered applicator where 2 clicks equals 0.1 ml, so you give the same measured dose every time.

Transdermal options on our standing formulary include methimazole, gabapentin, prednisolone, fluoxetine, mirtazapine and buprenorphine.

Flavored Oral Suspensions (Liquids)

A suspension is a liquid medication measured with an oral syringe. Liquids make it easy to give small, precise doses and are ideal for tiny pets, senior animals, and pets that can’t swallow a tablet. Most of our formulary is available as a suspension. 

Medicated Treats

Some medications can be made into a treat your pet thinks is a reward. We currently offer methimazole treats and prednisolone treats, and our customers tell us medicated cat treats make giving daily meds dramatically easier.

Mini Tabs, Chew Tabs and Capsules

For pets that do take pills, a properly sized tablet or capsule can remove the guesswork of splitting. We make gabapentin, metronidazole and mirtazapine mini tabs, potassium bromide (KBRO-VET) chew tabs, and capsules in many strengths, including custom strengths your vet specifies.

How to Order Compounded Pet Medication

For Pet Owners

  1. Talk to your veterinarian. Ask whether your pet’s medication can be compounded into an easier form, such as a liquid, a transdermal gel or a treat. Mention Watkins Pharmacy by name.
  2. Your vet sends the prescription. All compounds require a written prescription for each individual pet. Your vet can fax or email it to us, or use our veterinary prescription forms.
  3. We prepare the medication. Our compounding lab makes your pet’s medication to the prescribed strength and form.
  4. Pick up or have it delivered. Pick up at our Muskegon location, or ask about local delivery and shipping.

If you have questions before talking to your vet, call us at (231) 739-7158.

For Veterinarians and Clinic Staff

Our veterinary prescription forms cover our full standing formulary across five sheets, with checkboxes for strength, quantity, refills and SIG, plus space for patient weight, species and allergies.

Ways to send a prescription:

Please include the patient’s name, species, weight and any known allergies, along with the prescriber’s name, signature, DEA number (where required) and office phone. For controlled substances, contact the pharmacy directly. Hydrocodone prescriptions must be given to the pet owner in writing and cannot be called or faxed in.

Frequently Asked Questions

What is a veterinary compounding pharmacy?

A veterinary compounding pharmacy prepares custom medications for animals based on a veterinarian’s prescription. The pharmacist makes the medication in the specific strength, form and flavor a pet needs, such as a flavored liquid, a transdermal gel or a medicated treat, instead of a standard manufactured pill.

Do I need a prescription for compounded pet medication?

Yes. Every compounded medication at Watkins requires a written prescription from a veterinarian for each individual pet. Ask your vet to fax, email or call in the prescription to Watkins Pharmacy.

How does transdermal medication for cats work?

Transdermal medication is a gel applied to the skin, usually the inside of the ear, where it is absorbed into the body. It is a popular option for cats who refuse pills. Our transdermal gels use a metered applicator where 2 clicks equals 0.1 ml for consistent dosing. Your veterinarian will tell you how much to apply and how often. Wearing gloves or a finger cot when applying it is a good habit to avoid absorbing the medication yourself.

Can you make my pet's medication into a treat or flavored liquid?

Many medications can be. We currently make methimazole and prednisolone treats, and most of our formulary is available as an oral suspension. Ask your veterinarian which form is right for your pet, and call us if you want to check what’s possible for a specific medication.

What animals do you compound for?

Our formulary is used most often for cats and dogs, but compounding can help other animals too. Your veterinarian notes the species on the prescription so we can prepare the medication appropriately.

Can veterinarians order custom formulas not on your prescription forms?

Yes. Custom formulas are welcome. Veterinarians can call our compounding lab directly at (231) 683-1708 to discuss strengths, combinations and dosage forms.

Are compounded pet medications FDA approved?

No. Compounded medications are prepared by a licensed pharmacy for an individual patient under a veterinarian’s prescription, and they do not go through the FDA approval process. Watkins is PCAB accredited, which reflects an independent standard for compounding quality.
