Parasitic infections are something that I have become all to familiar with in the past year and have learned to diagnose and treat now on my own.
More than likely your vet will treat with fenbenzadole (I may have misspelled that )which is panacur and given antibiotic if the parasitic load has caused a respitory infection.
A good follow up is with a liquid base of Flagyl which will take care of abebic infections in the gut. THese medications require a follow up dose approximately 7-10 days later.
When all is said and done and the snake is free of parasites, I've recently been using a product called NutriBac probiotic to restore the good bacteria in the snakes digestive tracks.
I know there is some question as to whether this is necessary but I've had some very positive results with this product in a very short amount of time. From what I've seen I'm a believer.
I'd say if you address the problem now you have a very good chance that the problem can be corrected.
Lastly and very important, when you take your snake in to the vet bring the most recent stool sample you can collect. They will need that to determine what parasite you may be dealing with and the best course of action to take.
