Well, here is the honest answer (or at least in my opinion why
Using ivermectin orally for demodex is "off labeled" use.
That means that although it works like a charm, and is safe to most dogs (collie/aussie-types excluded
), it is not FDA approved for that purpose.
And, until that happens (which may never happen, because most drug companies aren't going to spend the time and money to "prove" something we already know works
, so to speak), there probably won't be any products coming out to help us with giving it orally.
There are compounding pharmacies, and even ones that will formulate it into a chewie very similar to the Heartgard, that can help.
I have no idea what the price for something like that would be. But I know we get flyers and such all the time, so I know it is done frequently.
I hope that helps a little.
I had a severe case of demodex in a collie cross puppy a few years back (FYI: it has now been proven that only certain genetic lines of these types of dogs are ivermectin sensitive. Problem is that we don't know who they are
, so why take the chance
). Again, using an off label dose, I was able to treat with the heartworm preventative Interceptor. This was SOOOOOO
I felt so bad for the owners, who luckily, were able to do it. It would be equally, if not more so, cost prohibitive to do that with the Heartgard tablets. DEMODEX IS A PAIN IN THE KEESTER!!!!
