This
letter is to inform you that we have recently stopped
using Proheart 6 in dogs. The drug was effective in preventing
heartworms but some concerns about the safety have arisen.
I recently had a dog which has had some problems after
vaccinations and Proheart were given. I referred the dog
to an internal medicine specialist. He felt there was
a possibility that Proheart was the cause. Fort Dodge's
(the maker) literature indicates this did not happen during
their trials. After more personal research about the problem,
I found that there have been several suspected but unproven
cases of problems after injections of Proheart. After
discussion with the internal medicine specialist, I have
decided to stop giving the Proheart injection until I'm
sure it cannot cause problems. (My own dog has had 4 injections
of Proheart without any problems.)
You may start your dog on a monthly preventative tablet
at the time he/she is due the Proheart injection without
any testing being done. |
