Changes to the treatment of Heartworm Disease in Dogs

Posted in [Animal Health], [Research] By Dr. Nieuwoudt

We have been treating dogs for heartworm disease routinely for sometime, using a drug called Immiticide (melarsomine dihydrochloride). It has been the only available heartworm killing agent for many years. There are no safe substitutes on the market. Recently the manufacturer, Merial, has informed the veterinary community that Immiticide is no longer available (for an unspecified duration).

Due to this deficiency the doctors at WRVMC are developing a protocol for treating heartworms based on the recommendations of the American Heartworm Society Board and Scientific Committee for dogs during the period of unavailability. The protocol is not  a permanent alternative to the the accepted treatment with Immiticide. It is an interim measure to prevent the disease from worsening while better alternatives or Immiticide become available.

For more information please call us or consult the Heartworm Society reference at:
