Evidence-based supplement guides for humans and pets, from our sister site Health Britannica.How This Tool Works
The Pet Prescription Savings Calculator compares medication prices across five pharmacies: Walmart, Costco, Amazon Pharmacy, Cost Plus Drugs, and your vet's in-house pharmacy. You search for your pet's medication by name, and the tool shows a price comparison table with the exact cost at each pharmacy, the savings versus your vet's price, and an annual savings projection. For medications available at human pharmacies (the majority of common pet drugs), the tool includes a step-by-step guide for getting a written prescription from your vet and filling it at the cheapest pharmacy. For vet-only drugs like Apoquel and Carprofen, the tool explains why no human generic exists and suggests cheaper alternatives your vet may be willing to prescribe instead.
Example Scenario
Your dog takes gabapentin daily for pain management, and your vet pharmacy charges $45 per month. You search "gabapentin" in the tool and discover it is on Walmart's $4 generic list. The comparison table shows Walmart at $4, Costco at $5.50, Cost Plus Drugs at $5.40, and Amazon Pharmacy at $6, compared to the $30 to $60 range at vet pharmacies. The annual savings calculator shows you would save over $490 per year by switching to Walmart. The how-to section explains that you simply ask your vet for a written prescription (they are legally required to provide one), take it to Walmart, and tell the pharmacist it is for your pet. The medication is identical; only the label changes.
Frequently Asked Questions
Is it legal to fill pet prescriptions at human pharmacies?
Yes, in all 50 US states. Pharmacies like Walmart, Costco, CVS, and Amazon Pharmacy legally fill pet prescriptions every day. Many common pet medications (gabapentin, amoxicillin, prednisone, fluoxetine, trazodone) are the exact same drugs used in human medicine. Ask your vet for a written prescription and bring it to any pharmacy.
Can my vet refuse to write a prescription?
Under FTC guidelines and most state veterinary practice acts, vets are required to provide a written prescription upon request. They cannot force you to buy from their in-house pharmacy. Some may charge a small prescription-writing fee, but they cannot refuse outright. If your vet refuses, you can file a complaint with your state veterinary licensing board.
What about vet-only medications?
Some drugs like Apoquel (oclacitinib), Carprofen (Rimadyl), and Cerenia (maropitant) have no human generic equivalent and can only be purchased from veterinary pharmacies or pet-specific online pharmacies like Chewy Pharmacy and 1-800-PetMeds. For these drugs, the tool suggests cheaper alternatives your vet may consider and links to discount programs.
How accurate are the prices?
Prices are based on publicly available pharmacy pricing data and represent typical costs for a 30-day supply. Actual prices vary by location, specific strength, and quantity. Walmart's $4 generic list is standardized nationally, but other pharmacy prices may differ slightly. Always confirm the final price with your pharmacist before filling.
