    How it works for a pet prescription

    1. 1

      Your vet writes the prescription

      Ask for a written or electronic prescription instead of buying from the clinic. Where you fill it is your choice.

    2. 2

      Upload it

      A photo or PDF of the vet’s prescription. It names your pet and the species; if a pharmacist needs the weight, they will ask.

    3. 3

      Pharmacies respond

      Licensed pharmacies, including compounders and those stocking veterinary products, quote their own cash price.

    4. 4

      Choose and pay the pharmacy

      Pick the quote that suits you and pay the pharmacy at the counter or on delivery. Nothing is paid on this site.

    Four things that are different for pets

    The medicine is often the same as for people. The safety rules are not, and these are the ones that catch owners out most often.

    • Xylitol in human liquids

      The sweetener in many human liquid medicines is poisonous to dogs. Ask the pharmacist to check any liquid, or ask the vet for tablets or a xylitol-free compounded version.

    • Cats and painkillers

      Cats cannot have acetaminophen (Tylenol) at all, and most anti-inflammatories are unsafe for them beyond a single vet-given dose. Never give a cat a human painkiller.

    • Two kinds of insulin syringe

      Veterinary insulins are U-40 and human insulins are U-100. The syringes differ, and the wrong one gives the wrong dose.

    • Doses follow weight and species

      Some drugs need far higher doses per kilogram in dogs than in people, and others far lower in cats. Never adjust a dose without the vet.

    Questions pet owners ask

    Anything else? Each medication guide covers the drug, the safety points for animals and how to pay less.

    Can a regular pharmacy fill a prescription from my vet?

    Yes, for any drug it stocks. Most medicines vets prescribe, from antibiotics to insulin to anxiety and thyroid medicines, are human drugs, and a licensed pharmacy dispenses them on a vet’s prescription exactly as it would for a person. Veterinary-only products such as Apoquel, Cerenia or carprofen are dispensed by vets and by pharmacies that stock veterinary products; each guide on this site says which applies.

    Can I ask my vet for a written prescription?

    Yes. Veterinarians provide a prescription on request so that you can have it filled elsewhere; some clinics charge a small fee for writing it. Rules on what must be provided vary by state, but asking is always reasonable, and the choice of where to fill it is yours.

    Is a human pharmacy safe for my pet’s medicine?

    The pharmacist dispenses what the vet wrote, and good pharmacists check that the dose makes sense for the species and weight. The risks come from products, not pharmacies: human liquids sweetened with xylitol are deadly to dogs, cats cannot have most NSAIDs or acetaminophen, and veterinary insulin needs its own syringes. Every guide here lists the points for that drug, and your vet remains the authority on the dose.

    What about compounded medicines?

    Compounding pharmacies make strengths and forms that are not sold ready-made: a tiny capsule for a cat, a flavored liquid, a transdermal gel. They are useful and legal when a vet prescribes them for an individual animal, and they can quote through Script Unlock like any other pharmacy. Compounded products are not FDA-approved and quality varies between compounders, so ask the pharmacy about its accreditation.

    Does Script Unlock charge pet owners?

    No. Pharmacies pay to use the marketplace. We publish no prices, savings figures or pharmacy counts; the quotes you receive are the only numbers that apply to your pet.
