Merial Re-Launches HEARTGARD® (ivermectin) Tablets for Dogs

Dogs with food ingredient allergies now have an alternative to help prevent heartworm disease

Duluth, Ga. – July 16, 2014 – Merial today announced the re-launch of its HEARTGARD® (ivermectin) Tablets. Dogs with food allergies now have a monthly heartworm preventive that does not include any food ingredients that may trigger an allergic reaction.

From the makers of HEARTGARD® Plus (ivermectin/pyrantel), the number one veterinary-recommended heartworm disease preventive, HEARTGARD Tablets help protect against heartworms that can lead to serious illness in dogs. Merial re-introduced these tablets to ensure that every dog has an option for heartworm disease prevention.

"Many dogs suffer from food allergies and most oral heartworm preventives have meat components in their formulation," saidDr. Michael Murray, Technical Marketing Director of U.S. Pets Parasiticides at Merial.[i] "Merial is committed to providing dogs with food allergies an alternative that delivers the same heartworm disease prevention found in HEARTGARD Plus (ivermectin/pyrantel), which is a real beef chewable."

HEARTGARD Tablets are now available through veterinary practices and are backed by the Plus Customer Satisfaction Guarantee, Merial's commitment to proven protection against heartworm disease.

"It is critically important that pet owners maintain year-round heartworm disease prevention every 30 days," added Dr. Murray. "For dogs with special dietary requirements, veterinarians can provide the heartworm protection these pets need with HEARTGARD Tablets."
