TRIFEXIS Heartworm Medicine.

Recently, there were internet and media rumors that TRIFEXIS Heartworm medicine was responsible for a few dog deaths. The AVMA investigated the claims. The deceased dogs were submitted to an independent pathologist for necropsy and pathology. A summary from the pathologist has since determined that the cause of the deaths were unrelated to the administration of Trifexis.  If anyone has additional questions concerning Trifexis, please contact us at your convenience or contact the manufacturer of the product - ELANCO.
