Can you use Nizoral shampoo for rain rot?

[IhaveTooMany]

As title says.
Reading so many conflicting remedies for rain rot. Horse came to me with this and wanting to clear it up for her.
I have nizoral at home and read it could be used but not confirmed anywhere

If you do a search for it on here you’d find people recommend it. I’ve used it for mud fever

Yes.
