I juuust went through this for the first time. It was a fun learning experience, haha.

I took her to the vet after 5 days of no improvement (had increased ambient temperature and was doing the Vicks and Eucalyptus sauna, which I learned is a very touch treatment, lots of people don't like it, some recommend it such as the vet I took her to and a friend of mine who also has snakes.). The vet gave me Baytril and about 13 needles to inject her with 0.1mL everyday for 5 days and then every other day for about a week. I discontinued the Vicks and Eucalyptus saunas as I was no longer sure about them after all the controversy over it and went on a cycle of using a humidifier in the same small room she was in.
I never got the fast improvements I've read about, it took her about three weeks till she started to shed that I noticed a difference. She never got bad enough that mucus was bubbling out of her mouth constantly, but it was smeared over her face and her nostrils were pretty plugged and dry. I gave her a bath to aid in her shed and it also cleared out her nostrils and the mucus hasn't build up again! She refused to eat, so I'm thinking she isn't back up to snuff but her nose is still clear and the wheezing has stopped. I'm not moving her out of the smaller, warmer room yet, will probably do so after she eats a few times.

I never got a blood culture done when I took her to the vet, which I guess is a no-no. The vet gave me the baytril based off his 35 years of experience with reptiles, and luckily he was right. It was just a bacterial infection, but RI's can be viral, in which case I believe Baytril won't help in curing the infection. It's better to get the culture done so the vet is definitely certain of what to prescribe. I was comfortable in giving her needles, some people do a tube feeding of medication that can be a lot more stressful. I've also heard of a spray form of Baytril that works faster than injections and they just inhale it as you spray their nose. The spray form and injection form can not be given at the same time, it's one or the other.

So after almost a month, my baby is getting back on track and this snake momma is happy and way less stressed now that I'm not pondering with unknowns! Hopefully this helps a bit, I've never had experience with the F10 mix. I kept her water bowl in her cage the whole time, she was in her hide most of the time anyways and the lamp was always above her and temps were never below 80 on the cool side. I was told to keep temps up to 100 max on the warm side.
