To this day, the top two sellers the animal health industry has ever produced are from Merial: our family of ivermectin-based parasticides and our FRONTLINE® flea and tick products - with literally billions of doses administered since the 1970s.

Our product portfolio

Merial's products cover the spectrum from preventive vaccines and parasiticides for every type of animal we support, to therapeutic medicines that treat key diseases in certain species.

Overall animal health management

You can never predict every disease or concern, but at Merial we firmly believe in taking a proactive approach to animal health when possible. We focus a large portion of our product development efforts on vaccines and other preventive medicines, with the aim of reducing the need for more intensive treatments later and giving animals not just healthier, but also happier and longer lives. 

We're aiming to launch 10 new products over the next 3 years.

Product News

The challenge: Put a powerful flea and tick fighting medicine into a form no dog could resist. The solution: NexGard® (afoxolaner), the first monthly flea and tick product in a tasty beef-flavored chew.

Ivermectin and the parasite-Fighting revolution

In the 1970s we partnered with researchers in Japan who had isolated a compound with powerful anti-parasitic properties. This collaboration led to ivermectin, a drug effective against a wide range of parasites in many animals.

In the decades since, Merial has produced ivermectin-based products for almost every species we support, from our well-known HEARTGARD® for cats and dogs to numerous treatments for large animals. It's an innovation that has truly revolutionized a major part of animal care — and human health as well. Ivermectin is also widely used to combat devastating parastic diseases in people, and it's for these contributions to humankind that the lead scientists who developed it were awarded the 2015 Nobel Prize in Physiology or Medicine.
