Virbac Recall 8-13On August 20, 2013, Virbac has issued another recall alert for Iverhart Plus Flavored Chewables due to several lots being below Ivermectin potency levels prior to their expiration.  There was a similar recall on August 13th, 2009 and on April 10th, 2013 for Virbac’s Iverhart Plus Flavored Chewable Tablets, due to Ivermectin stability concerns.  They found that certain lots were no longer effective for dogs weighing more than 75 pounds.
