Since I'm not seeing the issue real close up, it would be better to verify the issue first with your vet, so you're not using something ineffective for the issue at hand.
But IF it's what I think (fungal) what I used (from my vet) in the past was miconazole nitrate 1% ("Conofite" spray) which is actually sold for dogs & cats.![]()
Same ingredient is used in some antifungal products (topical use only!) for humans, but it's 2% instead of 1%, so maybe a bit too strong for pet use. It's used daily & it does take a while to clear up.
Might check & see if Chewy or Petco carry that product (Conofite 1% spray)?![]()
I cannot verify that ANY OTHER anti-fungal meds are safe for snake use, I would NOT use them, & that would be a question for your vet also.
Remember that topical meds are absorbed thru the skin, so use the LEAST amount that is effective. ONLY treat scales that are obviously affected.
I just looked at Chewy: you'd want either of the first 2 listed (lotion or spray, generic Miconazole nitrate 1%)
