Virbac Recalls Six Lots of Iverhart Plus Flavored Chewables

Virbac has issued a voluntary recall for six lots of their heartworm prentive, Iverhart Plus Flavored Chewables, due to a failure to meet stability specifications during the life of the product.

The following lots have been included in the recall:

  • Lot 120076 (Large 51-100 pounds)
  • Lot 120086 (Large 51-100 pounds)
  • Lot 120856 (Large 51-100 pounds)
  • Lot 120202 (Medium 26-50 pounds)
  • Lot 120196 (Small up to 25 pounds)
  • Lot 120844 (Small up to 25 pounds)

According to a Virbac letter obtained by petMD, the recalled lots met all of the specifications at the time of their release to distributers, but further product testing showed that the ivermectin potency failed to meet stability specifications during the life of the product.

The recalled lots may not fully protect dogs in the upper third of each weight range against heartworms. At the time of this letter, no heartworm-related adverse reactions or illnesses have been reported.

For questions or concerns about the Iverhart Plus recall, please contact Virbac Technical Services at 1-800-338-3659 ext. 3052.

    It is not surprising that these recalls are happening with predictable frequency. Few years ago there was a warning letter addressed to Virbac from FDA highlighting serious quality issues with this product. This was followed by a product recall few years later because ongoing stability issues and now this recall of the product again because of stability issues. This product is also hard to administer, has very poor palatability compared to Heart Guard and I always wonder why people by this product from a manufacturer with ongoing quality issues. Virbac still markets a product called Aquadent, a product that is not all effective in preventing plaque and tartar accumulation in dogs (and Virbac knew it all along) but also be potentially toxic to dogs.
