Subject: [ferrethealth] Re: Heartworm prevention -- Revolution question
To: "FHL" <>

Hi Jeff and others

For some time I've been getting the large dog version of Revolution (called
Stronghold in the UK/ Europe) and have split it up to treat the ferrets,
skunks, dogs, cats, rabbits and even a hedgehog we had. I used the dosage
instructions from this web page and did the
calculations how many ml's of Revolution to use.

Using the large dog vials is obviously very cost effective, at one time I
needed 3 large dog vials to treat all animals. Now my question: Is it okay
to use the dog version of Revolution for ferrets and other animals? My vet
seems to worry that the dog version is too strong (for my cats), since the
concentration of selamectin is 12% so double that of the cat version which
has a concentration of 6%. So I just wanted to ask what others think, I know
other ferret owners use the large dog vials but I just never thought of the
higher concentration of selamectin possibly causing harm. I've never noticed
any problems myself.


2. Heartworm prevention

I have used Revolution for several years now, once a month, during mosquito
season (usually May 1 – October 1 around here in CT). There may be some
debate as to just how much selemectin (the active ingredient in Revolution)
is needed to safely guard against heartworms. Some vets and studies
suggest it’s 12 mg per kg of body weight monthly, others 18 mg monthly, or
more. I feel it’s better to err on the side of caution, so I make sure mine
get at least 18 mg of selemectin monthly during mosquito season. This
translates to 1/2 of a tube of Revolution, the size for cats from 5-15 lbs.
This tube contains 45 mg total, so half a tube is approximately 22 mg,
something I’m comfortable with.
