Welcome-
So sorry that you had to join us, but this is the place to be for Blasto help.
We've all used several different anti-fungals, but Itraconazole seems to be the most common.
Sporanox (Itraconazole) is usually only available in a standard dose for humans. (100 mg.) It's very expensive, but generic is also available. As most dogs need a different dosage, compounding pharmacies make the generics in custom doses to fit the person or animal (Dirtbike had 150 mg. capsules from Pet Health Pharmacy in AZ, at a cost of about $80 for a 2 month's supply - I was very happy with it.)
While we've listed the ones we "trust" in the newsletter, compounding pharmacies are NOT regulated by the FDA. (But neither are companies who manufacture vitamins and supplements, so take that for what it's worth.)
There are many questions (see "Sporanox, Itraconazole, ending the controversy" by Gunner) regarding whether it's as effective, or whether the quality is the same. The law states that generics must be identical in every way except for the look and the inert ingredients.
Whether it works as well (I believe it does) is a matter of opinion. Knowing how to use it (many of us didn't at first), and what to expect from it are a different story.
Some vets didn't really expect the animal to survive and were making it up as they went along. They didn't tell us about the initial fungal die-off, or what to expect from treatment, either.
What we've found is that many vets don't even know; they just give you a scrip and you're on your own for at least 6 months of treatment. THAT is most likely the reason people have trouble.
None of the vets told us that Itra needs fat and stomach acid to even get into the bloodstream, so it's wasted on a dog with an empty stomach. Hence the margarine, the bologna, peanutbutter dosing. It also makes them anorexic, so it's sometimes necessary to force-feed them, esp. just some fat with their dose.
The oral suspension doesn't need food, but only a very few have used it.
So, the best thing to do is download or print off a copy of our Blastomycosis Newsletter. (It's printed iin 2 topics here.)
It should answer many questions, and help you know what things you may expect. It was our goal to put everything we've learned into one format.
When I first came here in April '07, very few dogs were making it.
Now we know a lot more, and with everyone's help and input, many more dogs are having a good outcome.
Good luck, and let us know what's going on.
We're all very nosy and must know how you and Harley are doing at all times.
