The Same Medications for Humans are Pricier than for Pets

In a research letter published in JAMA Internal Medicine, researchers compared the prices of 120 medications commonly used in humans and pets. The authors found human medication prices were typically higher than the price of pet medications – with the same ingredients at common human-equivalent doses.

While some medications are common to both pets and humans, but price differences can be extreme. In 1991, levamisole (introduced in the 1960s as a veterinary antiparasitic) demonstrated efficacy in treating human colon cancer. The introductory human price of Janssen’s Ergamisol (brand-name levamisole; $5 per 50mg tablet) was 100 times the then veterinary price (approximately $0.05 for an equivalent amount). With the COVID pandemic, a misinformation-driven demand for ivermectin as a COVID treatment led to people seeking veterinary formulations of the drug, increasing the price 15-fold over a month ($6 to $92 for 3 tubes). In this cross-sectional study, the researchers sought to compare prices of commonly prescribed medications used to treat both humans and pets.

The researchers from the University of Minnesota found that retail price for human medications was on average 5.5 times higher than pet medications. For more than 60% of medications, even discounted prices for humans were higher than pet prices. On average, discounted prices were 1.5 times higher for human medications than for pet medications.

‘’A 10-day supply of the same medication costs $2 for a pet dog, $10 for a person with a discount coupon, and $100 for a person without a coupon,” said Arjun Gupta, MBBS, assistant professor at the U of M Medical School and oncologist with M Health Fairview. He is also a member of the Masonic Cancer Center. “With many humans and pets uninsured or underinsured, it is important that cash prices for medications are affordable and that pricing is not exploitative.”

Human prices were also higher than pet prices for drugs such as antibiotics. Researchers warn this may promote humans sourcing antibiotics for their own use from pet sources, especially since human antibiotic use is more regulated.

Exactly why there is such a significant price difference is unclear. One possibility may be drug manufacturers engaging in price discrimination by charging consumers different prices in different markets for the same product, the researchers suggest. Additionally, price differences could reflect variations in medication effectiveness, willingness to pay, and manufacturing, storage, and regulatory standards.

Further research is suggested to explore the causes of price differences.
