I googled, and one site referenced this site, where I found this.

Treatments that have had success:
MAKE SURE YOU CONSULT WITH YOUR VETERINARIAN BEFORE ATTEMPTING TO MEDICATE ANY ANIMAL
Bathing/soaking- Nolvasan or a genetic of it:. Nolvasan soaks or spray on the affected area (not the eyes) and at least one inch out from the areas you see affected for at least 20 - 30minutes in the AM. What I have done is set them in a rubberrmaid or sterlite tub ans misted the areas. For around the eyes use a q-tip to apply the Nolvasan and keep it out of the eyes. Rinse, dry and then put on a thin layer of the lamisil. Repeat the thin layer of lamisil at night again. If the skin/scales get too sore, you can cut back to every other day for the soaks and clear water rinses.. The Nolvasan is very vital to the treatment, without it you are not reaching the active fungus or you are just appling the Topicals to dead tissue. You may see skin/scales slough off, the Nolvasan is not causing this, it is already there as dead skin and scales, the Nolvasan is only revealing it. Contact me if you have any questions about this and I do have photos of it also, this may happen and is normal if the fungus has got deep into the tissue.
Topical (external) Medication: Miconazole 2%; Tioconazole ( this is found in Monistat); Lamisil, or any product with terbinafine hydrochloride 1% in it; this from the data we have collected is the most effective in turning the fungus black and killing it externally; You can also use Zylafen; Gentamicin Sulfate and Gentamicin Sulfate Ophthalmic solution 0.3% to treat the wounds with.
Probiotics: We found a good product called Acidophiliz+, that is said to be Veterinarian recommended and we also note that it contains the two main ingredients that we have had good success with and the bearded dragons took well. It is made by Pet Authority and we located it in a pet store chain, but you can order it online if you click on the name of it above. Give the reptile some Acidolphiliz+ daily to try and restore the gut fauna with good bacteria. Use Up to 1/2 a dropper of Acidolphiliz+ (but at least .10 cc).
Possible other sources of replacement of "Good Bacteria" : Acidophilus, Nutra-Bac, Essential Probiotics, Bifidus Balance, Jarro-Dophilus, Nutri-Bac and Acidophilus Blend Digestive Suppory by Rexell found in Walmarts.
Oral (internal) Medications: These MUST be Medically Supervised by a veterinarian. These can be harsh meds on their systems and this needs to be discussed in detail with your Vet and you aware of possible side affects We can not stress enough watching
hydration, these meds are especially harsh on kidneys and livers when they already have internal problems with them from the fungus: Fluconazole; Itraconazole; Terbinafine (only one type used at a time). Oral antifungal are a last ditch effort AFTER all else has fails.
I suggest you follow the other treatment routine information exactly first to see if it can be controlled or cleared it first without the harsh medications and the problems they add. We have spent years working with these routines now and hundreds of dragons to get this one that is the most successful with least side affects. Many times, for some reason, people do not follow it or leave out one of the factors and then have problems still or lose their dragons. I suggest you only go to oral antifungal medications as a final resource to save them. There are some being tested with Nystatin right now that seems to be tolerated betters than the iothers listed above, so I will keep this updated on that or discuss it with your veterinarian and see what they suggest.
Bearded dragons that have contracted the external fungus from another dragon, rather than being producers (dragons which have developed the infection internally possibly after treatment with antibiotics), may not need to be treated internally with the oral medications. Often the soaks and topical anitfungals will clear them or other added items that will be listed below.
Other Options besides Oral Antifungal Medications: Both the Echinacea and the Grapefruit Seed Extract are showing success in really hard to treat animals that the nolvasan and topical antifungal are not clearing. Also in ones that react poorly to the internal antifungal medications They come in a liquid form and you can add a drop or two of each to some food that you know they eat all of. This has worked when even the oral meds were failing or taking their toll on dragons and they needed to be taken off them.
Use a non particle substrate while treating, shelf liner, paper towel or carpet is best and change it, wipe down or clean it daily
Time Duration: Keep up all treatment for at least 2 weeks past the time you see the last traces of any active fungus. If it returns, restart the same routine and continue it longer past the time you see it clear, I recommend a month.
Please discuss with your veterinarian about trying this routine before you try the harsher oral antifungal and if it fails then you can try them later, also stop all fruits. Fruits have sugar, sugar feeds molds/yeast, you need to delete the sugars from their diets while treating them for yellow fungus. Give fresh rich greens, pellets if your can not do insects or fed them insect, they need some animals protein to help fight this and keep their immune system strong[/p].

Good luck you could maybe discuss those other treatments
She successfully treated a tegu with yellow fungus, so she does have a personal experience dealing with it, just like the other doc. And she told me, "It's a very LONNNNG process." Yeah, I know. 
I have her Ceftazadime injections for the bacterial infection. She gets one shot every 3 days, 7 doses total. The IC will be given one week on, 3 weeks off. I was given a big tube of Bene-Bac gel for the probiotic. She will get that everyday (she's already been getting that 2x a week anyway) And so it begins.... 8)
