Sorry you misread my post, but at no time did I recommend Tylan. And I did make reference to talking with the vet before moving forward. However I will disagree with you on something. Tylan is an over the counter drug. You do not need a qualified vet to prescribe it. Thousands of farmers give this product to their chickens and pigs regularly to treat RI's. Second the reason I suggested a PM to me was because I don't want to give out my telephone number publicly, not to push Tylan on the OP where nobody can contradict me. The fact is that the old "don't do anything every without a vet...EVER" is played out. It is like telling teenagers not to have sex at all. They are going to, just the same people are going to try things with their snakes without paying a vet, because maybe they can't afford it. Information on all options is important. And like I said thousands of farmers pump Tylan into their livestock, so it really comes down to risk, cost, and personal value of the animal....which is never the same from one person to the next. My vet said that after the Tazicef didn't work her next shot in the dark without a culture would have been Tylan. Now I noticed an immediate improvement in the snake by shot two of the Tylan and in my opinion (not proven) their is limited risk vs. reward at trying it. If I ever recieve another snake with a RI, I most definitely would try Tylan before bringing to my vet. And I can do that because it is my snake and it is an over the counter drug.
